Tommy Oliver returned to his role as a  Power Ranger. In the years following turbo ( with Forever red in between) Oliver experimented with Anton Mercer to create creatures from dinosaur DNA. Dr. Mercer disappeared and a evil creature named Mesagog showed up. He captured and used  Tommy's experiments for evil. Tommy escaped from Mesogog and didn't see him for years after. Tommy became a high school science teacher.   Tommy had already constructed a secret base and had prepared for the day Mesagog would return. When Mesogog did return, he recruited three of his high school students to become Power Rangers. Tommy  became a role model for these kids. Mesogog captured Tommy in hopes that he could help him open a new power source  he had found. Luckily the DT rangers ( now knowing their mentor's true history as a Power Ranger) were able to save him. Oliver opened the new power source and received the black Dino gem. This gave him the power of invisibility and much more. Using a morpher made by a friend, Oliver was able to morph into the black ranger. Early on Oliver got into a rivalry with Zeltrax. At first Oliver didn't know why Zeltrax was so angry at him. Much later he found out that Zeltrax was his old rival Terrance Smith. Tommy operated the Brachio zord ( a carrier zord that can carry all the other zords). Oliver helped the Rangers  find many Dino eggs, given them additional zords and weaponery. Reefside High's Principal Randal  tried to get close to the doctor. She was really Elsa in disguise and was trying to gain Dr. Oliver's trust in order to defeat him. When Olivier discovered Trent was the White Ranger, the evil Ranger was quick to freeze him in amber. The Rangers were able to free him but now Tommy was stuck in his morphed form.  He was still able to assist the other DT ranger in the fight (till his demorphing problems were solved). Oliver quickly accepted Trent into the team when he became good again. He used his new charge to help unearth the Trassic Shield. Dr. Oliver was forced to finally destory his old friend Smitty in a clamactic battle.  Oliver used  strange goo in an attempt to demorph. The goo made him invisible instead. Later Oliver tried using his dino gem to restore himself to normal. This restored him to normal ( visible and demorpehd) but left him in coma.  In the coma Tommy fought three of his past Ranger forms ( green, white, and zeo). Once Tommy was victorious he awoke form his coma and helped the Rangers against Mesogog's latest monster. He also acchived his Super Dino Mode for the first time. Tommy was now able to resume his duties as  a teacher at Reefside High. Oliver was shocked to see Zeltrax return. He decided that  he'd better search for him before anything bad happened. Tommy often pioleted the Mezadon Megazord when Conner was busy in another megazord. Oliver was shocked to learn that Randall was actually Elsa in disguise. He was also shocked to learn that Mesogog was Mercer's alter ego. What shocked him the most was that Trent knew about Mercer's true idenity the whole time. After listening to Trent and seeing him in battle Oliver was able to forgive the young Ranger. Oliver was shocked when Elsa was revealed to be a innocent civilian bended to Mesogog's will. Oliver introduced the team to the new Dino Assualt Vichule. He led the team on an assualt on Mesagog's Island. The team stopped Mesogog's plan to turn humans into Mutant Dinosuars. Oliver fought Zeltrax in his new ZelZord. After the zord was distoryed Oliver and Kria finished Zeltrax for good. In final battle against Mesogog, Oliver surrenderd all his gems power to defeat the evil creature. Oliver enjoyed the prom and was happy to continue teaching at Reefside for the time being.

Conner was a star soccer player who only cared about playing the game. He is the brother of Eric McKnight (a Ninja Student who flunked out of the Wind Ninja Academy).He was so good he never learned team work or what it really took to be a good leader. Deep down inside he has the potential to be a good leader. He found the tyrannosaurus Dinosaur Gem and was chosen to be the Dino Red Ranger. He was on a trip  to a museum as part of his detention with Oliver. He stumbled on the gems along with the other rangers. The gem gave him the power to stop time. He used the morpher that Dr. Oliver gave him to become the red dino ranger. He quickly bonded with the Tyrannosaurus Dino Zord. At first Conner felt that being a Ranger was getting in the way of his soccer dreams. Conner almost quit  being a Ranger but soon realized being a Ranger was far more important. Since then Conner has become a dedicated member of the team. Sometimes he has a tendency to say bonehead things or to act overly macho. This gets him into numerous playful arguments with the intelligent Ethan. But deep down Conner is an intelligent and caring individual. When the Rangers faced the evil White Ranger Conner was the one that was able to be most successful against him. Conner was the first Ranger to discover his super Dino mode. Conner was very hard on Trent when he went bad. When Trent jioned the team he was still distrust full of the White Ranger. Conner was soon given the Trassic Powers  he used them to become the Trassic Ranger. Along with his new powers came a  new zord, the Mezadon Rover.  Conner was happy when Dr. Oliver was restored to normal. Conenr meant a girl named Trista and admire her dedication to save a tree. When Christa was in captured by Zeltra Conner looked deep with himself to discover his battleizer. He used him to go into his megabattle mode and save Christa from Zeltrax. Conner used his new Trassic and Battlizer powers frequently. He was shocked to learn that Elsa and Principal Randal were one in the same. He was also shocked to learn Mercer was Mesogog and that Trent had lied to them He was most critical of Trent when the Rangers questioned him about his actions. Trent daved Conner in battle. After here Trent's side of the story Conner was willing to forgive Trent. He jioned the Rnagers in the new mobile assualt vichule when they attacked Mesogog's island. Mesogog's island was distoryed along with Mesogog's plan. Conner jioned the team to defeat Zeltrax's Zelzord.

Kira was a very strong and caring person. She was into rock music and played in her own band. She found the yellow Dino gem with a few of her classmates. The gem gave her the power to let out powerful blasts of energy with her voice Dr. Oliver gave her  a morpher that allowed her to become the yellow Dino Ranger. She bonded with the Ptera Dino Zord/ She was friends with the pop diva Kyley . The two had a band together before Kyley got famous. The two lost track of each other after that but were recently able to come to an understanding. Kira began to spend a lot of time with Trent. She definitely showed affection to him and seemed to really like him. Unfortunately Trent became the evil white ranger by a sad twist of fate. Kira was shocked when Trent revealed this to her. She realized Trent was under an evil influence and wanted to help him ( even when her teammates doubted Trent's sincerity). Unfortunately Trent has fully succumbed to the white Dino gem's evil power. Kira was able to access her super Dino mode ( giving her the ability to fly, among other things). Kira was taken over by an evil mind control monster that Oliver and Mercer created and later disabled ( when it got out of control). She helped the monster become operable again. Kira was freed from the monster's control and helped her friends destroy threat. Kira interned at a kids show. At first it was shard for her but that it got better. Kira was happy when Trent became good again and jioned the team. She was given the opertunity to do a music video by a producer but decides to do it on her own because the producer was trying to changer her. Kira was reluctant to make firends with Cassidy when Ethan asked her to. She used her job as an intern to help get Cassidy a job at a TV Station. Cassidy thanked here for the opertunity. Kira gave was able to temporally giver he powers up to help Conner become the Trassic Ranger. She was happy to see Dr. Oliver restored to normal. She was shocked to leanr Esla and Randal's true identiy. She didn;t like that Trent had lied to the Ranger bust seemed to undertstand his piont of view.

Ethan only really cared about video games and computers. He really is a genius when it comes to that kind of stuff Once he found the blue gem and became the Blue Dino Ranger he finally had to focus on the real world. The blue gem gave Ethan the power to use video game like strength. Oliver's morpher allowed him to morph into a Ranger. Ethan bonded with the Tricera Dino zord. Ethan is an excellent foil to the jock ways of Conner. The two often have arguments full of witty dialogue Ethan introduced his new Ranger friends to the cyber cafe and its owner Hayley ( who later became a powerful ally). Ethan's love of video games got him in big trouble when one of Mesagog's monsters trapped him in one. Luckily he was able to escape. When the white ranger showed up Ethan scrambled to help his friend fight the evil ranger. When he found out his good friend, Trent was the evil Ranger he quickly felt Trent betrayed him. Ethan found more power by finding his super Dino mode. Ethan was tormented by a Bully but used his brain to help the soccer playing Bully improve his game. This made the Bully respect him. Ethan accepted Trent into the team when he became good. Ethan was able to help Conner become the Trassic Ranger. Ethan made firends with Cassidy and tried to date her. The relationship didn't work out when the two realized they had nothing in common. They decided to stay friends.   Ethan was happy when Dr.Oliver was restored to normal . Ethan  was confident when the annual video game contest came around.  He was troubled to see Devin beat him in the finals.  Ethan was distressed when Randal took a prized card in his card game collection. He was shocked to learn Randal was Elsa. He helped the team defeat the monster Elsa created from the card. Ethan found out Mercer was Mesogog's alter ego and was mad Trent lied to him. He was able to forgive Trent after hearing his side of things. Ethan helped the Rangers distory Mesogog's powerful weapon. This caused the villian's island to explode. He helped his friends defeat the Zelzord. In a final battle with Mesogog Ethan surrendered all of his power to defeat the evil villian.

Trent was a new kid who meant the Rangers when he started a job at Haley's Cyber Cafe. He was also in Dr. Oliver's paleontology class. He became quick friends with the Rangers, particularly Kira.  Trent is the adopted son of Oliver's estranged colleague Dr. Anton Mercer. Trent's parents died while working for Dr. Mercer. The Doctor took Trent in as his own. Trent loved his dad but often got into arguments with him regarding Trent's ability to draw . Mercer thought that was beneath his son who was supposed to take over his business Mercer felt it was beneath Trent to be a waiter at the cyber cafe so he tried to buy the place for Trent to run. Trent helped the Rangers foil his dad's bid to buy the place, so Hayley could keep her restaurant. Trent began to see some really weird things around his father's office. He found an invisi-portal  which really freaked him out. Mercer was very vague about everything when Trent approached him. Trent found a portal to Mesagog's lair and found the white Dino gem. The gem slowly began to take him over, turning him into the evil White Ranger. The White Ranger became a powerful adversary to the Rangers. Mesagog tried to convince him to join with him. But the evil Ranger preferred to work on his own. The white ranger temporarily trapped Dr. Oliver in amber ( the Rangers were able to free him). Trent revealed his predicament to Kira who tried to help him. Trent tried to run far away from the rangers so he wouldn't hurt anyone when the Dino gem fully took him over. A meteor changed Trent's fortunes and made the White power good. But once the meteor's effects were over the White power not only was evil but fully overtook Trent as well. The now evil Trent gained the power of  camouflage Trent has the power of the White Dragozord and has stolen many of the rangers zords. He can use the Megazord to form with the Dragozord (to form his own Megazord). Trent made  a temporary deal with Mesagog to trick the rangers into thinking he was free of the spell. He used this plan to get to the Rangers' zords. Trent found out that his father was in fact Mesagog. When he tried to conspire with Zeltrax to overthrow Mesagog in exchange for Oliver's defeat Mesagog caught him in the act (Zeltrax told Mesagog about his plan). Trent professed his loyalty to his father and jioned his armies. He beat Zeltrax in a battle to settle who was second in command. That didn't last long as Mesagog found out that Trent messed up his lab. At the same time Trent found out that his father Anton didn/t want what Mesagog (his unwilling alter ego) wanted. When Mesogog had Trent captured a freak accident returned Trent to his normal self.  Trent jioned up wth the other rangers. Zeltrax was able to clone an evil double of him however. Trent faces a little distrust from his former teammates but tried to do his best to show he was good again. He went back to work for Hayley and helped retrieve the Trassic Sheild.  Trent was happy to see Dr. Oliver restored to normal. Trent continued to worry about his father and hoped he would find away to free himself of Mesagog. Trent realizied his powers were acting stange.  Trent was forced to battle his evil clone since the morphing grid could only support one ranger. Trent was victorious and was able to help his friends defeat one of Mesogog's monsters that day. Trent continued to worry about his dad and was tempted to tell the Rangers of his Secret.  Trent met an comic book artist he admired. When Mesgog used the artist's talent against the Ranger Trent was able to draw a happy ending. He also recieved his father's acceptance to be an artist. Trent risked his life in an attempt to retrieve Ethan's card from Elsa. He failed do so before she turned it into a monster.  This caused the Rangers to question what Trent was hiding. After the monster was defeated  the Rangers discovered Mercer's problem. They were mad Trent lied to him the whole time. Trent explained that Mercer was the only father he had and he was only trying to protect him. Trent saved Conner in battle and proved his loyalty to the team. When Trent discovered his father was not split from Mesogog he devised a plan to pretend to turn the gems into Mesogog in order to save his father and allow the Rangers entrance to the villian's Island( they needed to destroy his new weapon). The plan backfired a bit but the mission was accomplished. Trent retieved the Dino Gems from his dad , escaping the Island before its disturction. Trent helped his friends defeat Zelzord and surrendeed all his power to defeat Mesogog. Trent planned to attend Art School in the fall.
