Adam Park

Adam Park is the Zeo and Turbo Green Ranger.

Mighty Morphin Power Rangers
Adam first met the Rangers during an attempt to save his teacher's baby alongside his friends Rocky DeSantos and Aisha Campbell. The three of them had previously lived in Stone Canyon, California and were visiting Angel Grove for the Final Round of the Team Ninja competition. To the Rangers' surprise, the Stone Canyon trio were not there as spectators, but to compete in the final round of the tournament, and they ultimately won.

Adam's new friendship with Billy, Kimberly and Tommy would lead to his, Aisha's and Rocky's constant entanglement in Lord Zedd's schemes. After winning the tournament, the three Stone Canyon teens were kidnapped by Goldar and chained together inside a cave. A snake whose bite would render them evil permanently was set loose on them by Goldar in order to make them Zedd's dark warriors. Their attempt to escape almost succeeded, but ultimately failed; it was the morphed Kimberly, Billy and Tommy who rescue them. Billy managed to wrestle the snake away so that the teens could be freed; however, despite Kim's destruction of the snake, the injuries it caused to Billy's neck forced him to remove his helmet to prevent suffocation. Though able to breathe again, Billy's identity as a Power Ranger, along with Kim and Tommy's, were revealed to Adam and his friends. The three teens would be taken to the Command Center where the identities of Jason, Zack, and Trini would be revealed to them and they would take an oath not to reveal their identities.

Adam was selected to take Zack's place as the Black Mighty Morphin Power Ranger when he left to attend the World Peace Conference as an ambassador in Switzerland. Rocky and Aisha also took over Jason and Trini's places respectively, and the new Rangers would subsequently move to Angel Grove and transfer over to Angel Grove High with the other Rangers.

Adam's character was more revealed after becoming a Ranger. As a kid, he was often picked on and left out, but he eventually built up confidence in himself while training in martial arts, though he still had problems with girls. During this time, he was targeted by Scorpina, who disguised herself as a girl named Sabrina in order to manipulate the shy teen into alienating his friends before facing an ambush alone, perpetrated by the Scorpion Warrior. Even though Aisha didn't trust Sabrina, she attempted to get along with her for Adam's sake. This led to her being able to interfere when Scorpina lured Adam on a hike to a remote part of the park. Though the encounter left Adam's confidence in himself weakened, he would soon recover when he gained the attention of a girl Aisha had been trying to hook him up with.

When Rito Revolto joined Zedd and Rita and destroyed the Thunderzords, Adam gained new Ninja powers of the Frog, becoming the Black Ninja Ranger. He also gained the ability to pilot the Frog Ninjazord and later the Black Shogunzord. He was also later granted the power of the Metallic Armor.

When Master Vile (Rita Repulsa's father) came to Earth to retrieve the Zeo Crystal, the Rangers managed to retrieve it first. To ensure that Master Vile couldn't get it again, the Rangers split the Zeo Crystal into five sub-crystals and sent them to different points in history.

Vile then turned back time using the Orb of Doom, turning the Rangers back into children (unlike last time, they retained their memories). The Rangers recruited the Aquitian Rangers to fight in their stead. Billy had then created a device which would restore them to their old selves. He used the Ninja Coins as a power source, testing it on himself. This worked, but it allowed Goldar to capture the coins and Zedd and Rita destroyed them.

When Zordon revealed that the Ranger kids had to seek the Zeo Crystal, each kid was sent to a different place and time, where his or her ancestors were. Adam was transported to the past North Korea, near where his grandmother was born, to recover his part of the Zeo Crystal. He met Kai-Ogi, a local sage, and found the Zeo Sub-Crystal behind a waterfall.

Zeo Power Rangers
When Adam's fragment of the Zeo Crystal was reunited with the four other fragments, he reverted to his normal age. However, trouble once again brewed when King Mondo and his Machine Empire drove Rita and Zedd away to begin his own conquest for Earth. With their powers destroyed, Adam and the Rangers used the reformed Zeo Crystal to harness new powers. With the Rectangle Sub-Crystal, Adam became Zeo Ranger IV: Green, and he gained the Zeozord 4.

After Trey of Triforia had revealed his identity as the Gold Ranger, he gave the Rangers the Super Zeo Gems and Super Zeo Zords. Adam received the Green Super Zeo Crystal and Super ZeoZord IV.

Turbo Power Rangers
When the evil Space Pirate Divatox threatens to raise a powerful monster named Maligore to marry her, Adam, along with the other Rangers, accepted new Turbo powers and becomes the Green Turbo Ranger, and gains the Desert Thunder Turbozord.

After graduating from Angel Grove High School, he decided to spend the summer coaching soccer, among other things. There, he met Carlos Vallerte, and encouraged him to use teamwork rather than try to win every game solo.

When it came time for the rangers to choose successors, as Zordon wished to release them from their duties, he chose Carlos Vallerte to take his place as the Green Turbo Ranger.

Space Power Rangers
During a mission, Carlos - Adam's successor and the Black Space Ranger - hurt his teammate, Cassie Chan, during a battle in which a monster traded places with her while he was in mid-attack. Carlos was deeply affected by this and chose to retire as a Ranger. To help him gain his confidence, Adam returned and helped Carlos train both physically and mentally; even going as far as to teach Carlos how to fight by relying on his instincts rather than his vision. Adam told Alpha, who was also helping, that he missed being a Ranger and revealed he had kept his broken Morpher and damaged Mastodon Power Coin, but Alpha warned him not to morph with it as its link to the Morphing Grid was destroyed, rendering it highly unstable. When they were attacked, as Carlos left his Astro Morpher behind, Adam took the risk and morphed into the Black Mighty Morphin' Power Ranger once again.

Seeing Adam take the risk of morphing renewed Carlos' confidence, and he became a stronger Ranger. However, due to an unstable connection to the Morphing Grid, the Black Ranger powers quickly began to fail and left Adam incredibly weak (very nearly killing him). Adam managed to survive and decided not to risk morphing again.

Operation Overdrive Power Rangers
Nearly nine years later, Adam would be called back to action once more. The Sentinel Knight came to ask Adam for help in protecting the jewels of the Corona Aurora, after the Operation Overdrive Power Rangers were disconnected from the Morphing Grid by Rita and Zedd's son Thrax. Adam was more than happy to help, and the Knight restored his Black Ranger powers, albeit permanently this time. Until the Overdrive Power Rangers were able to restore their powers, as the veteran Ranger, Adam led the team of four other veteran Power Rangers (or Retro Rangers) in defending the world from Thrax's evil alliance.

He was the only Ranger called in to replace the Overdrive team that did not have any powers outside being morphed. While fighting Chillers, he simply commented "It may be old school, but it gets the job done", referencing how Kira, Tori, Xander and Bridge had powers useful in regular fights while he used martial arts.

Currently, Adam owns a Martial Arts dojo in Angel Grove and retains the newly reconnected Alpha 6 by his side at the dojo, possibly as an assistant.

Adam uses the Operation Overdrive arsenal three times in battle. In a fight against Flurious, Adam arrives in Angel Grove on the Hovertek Cycle. In the final battle, Adam takes on Thrax solo and uses the Defender Vest for protection (which was overpowered by the villain). He also used the Flash Point Megazord against Vulturus. However, Adam preferred to use his Power Axe.

Power Rangers Ultimate Alliance
Adam was later called upon to the Abyss of Evil to stop the villains from drilling into the surface. He could use his Zeo and Turbo Green Ranger powers. Due to his DNA altering in the terraportal, he could not go through the forcefield surrounding their base without changing into his child form unless he was in his ranger form.

Power Rangers Super Legends 2
Adam appears in the Mighty Morphin arc as the Black Ranger after Katherine and before Billy. Zordon tells him where the Tablet Key is and he makes his way to the building in Angel Grove, but none of the arifacts there is the Tablet Key. He then becomes playable in free play.
