20XX Remix Cast
 

X is an elite Maverick hunter in 21XX. He is sent into the past by Dr. Cain to investigate the emergence of Reploid viruses. Incredibly brave and powerful, he is the leader of his own brigade of Maverick Hunters.

 
Zero is also an elite Maverick hunter and X's best friend. After X travels to the past, he remains in 21XX to handle things while X is gone. After traveling to the past, X and Tempo discover that it was actually Zero who caused the great Cataclysm.
 
A high-ranking Maverick Hunter in 21XX, Solo also volunteered for the mission to the past. It seems that he has located the source of the virus and destroyed it. He is very powerful but prefers to work alone.
 
Nega Solo is the result of Solo's direct infusion with the original Maverick Virus core. Essentially he is the virus. He is able to easily conquer all machinery in the future within hours and challenges X to a final showdown.
 
The mysterious android "Tempo" was originally created as a very early version of a humanoid robot by Dr. Light and Dr. Wily. He was underdeveloped, and although he was able to easily handle minion robots, he was no match for Dr. Wily's Cut Man.
 
Tempo, after recieving an upgrade from Dr. Cain in the original version of 21XX, became substantially more powerful. He was equipped with a cutting-edge motion accelerator and a new model of energy saber. However, he still lacked experience and was caught in the crossfire during the battle with Zero. He has since been upgraded yet again, but his power has yet to be tested.
 
Dr. Benjamin Light, an indirect descendent of Tempo and X's creator, has chosen to repair and build common robots, rather than revolutionize the science like his ancestor. He upgrades and repairs the original reploid crew, and is wise enough to not have their weapons confiscated.
