Jim (also known as Evil Tim) is the main antagonist and anti-hero of Time Travel Adventures.

Extinction
Jim debuts in the 1st ending of the Extinction map. He reveal that he is Tim from an another dimension. He tries to take the gem from Tim, but fails to do so as he is approached by a T-Rex who helps us in the 1st ending of Extinction.

Mummy Mystery
Jim reappears in Mummy Mystery where he tries to take the gem in the map. He makes Manny out of one of the gems (The cyan/light blue one. He dropped the green gem in Extinction) to try to kill the player (or players) which then lead to a boss fight with Manny.

Wild West
Jim appears again in Wild West but seems unable to do anything as he is all bloody. He gives back the gem (most likely the dark blue one) then tells us he was wrong about us. When he tries to say who did it all he is presumed dead as it cuts to a black screen saying, "Finale coming August 2nd!" and Jim said 'don't trust'

Medieval Madness
Jim is briefly mentioned in Medieval Madness, as it was revealed he is Tim's brother.
