Axel tries to figure out what happened to his dad, using everything he can remember to unlock the codes and his dad's files. Dragon appears out of the blue and engages Axel in a fight.

In the end, it is revealed that the government was trying to clone a super-human, and all clones were marked with tattoos on their chests.
