Jake Thompson-Park, also known as Plain Jake is an ordinary teenager from a world where the Osborn experiment never took place.
Physical appearance
He looks exactly like Prime Jake at the beginning of the series: his favorite yellow hoodie, blue jeans, and black and white sneakers. However, he lacks that electric spark in his eyes and his posture is a little less sure-footed. He doesn't have a costume, but he always wears a blue wristband as a symbol of courage.
Personality
Plain Jake is a bit more withdrawn and unsure of his musical talent (J-Trixx is just a dream in his diary). He is extremely intelligent, but he uses his mind to fix junk in his father's garage, not to build hi-tech gadgets. However, his sense of justice is just as strong. When the multiverse is in danger, he is the only one who does not rely on powers, which makes him immune to energy-draining attacks (such as the one from Voltage).
Abilities
Pure Parkour: Without augmented reflexes, he trained himself. He is incredibly agile and can navigate New York using only his environment.
Genius in Improvisation: Can transform mundane objects (a fire extinguisher, a high-voltage cable, a car battery) into tactical weapons.
Empathic Strategy: Understands people better than its strong variants, being the one who often manages to "reach" the soul of enemies.
Trivia
In his universe, he has a very normal and nice relationship with Sally, who is not a ninja, but just a high school classmate who is passionate about reading.
In this universe, his mother is a lawyer named Park Hyo-rin, instead of a Galra undercover operative of the Blade of Marmora.
