Mega Man Zero/Characters

Resistance members
Note that most Resistance members are named after birds, and the name of their leader is "Sky". It's symbolic: these Reploids are free in Ciel's Resistance outside Neo Arcadia, in the same way birds are free in the sky outside a cage.

It's hard to see, but small floor numbers are written on the background behind the elevator.

The Resistance Base get more populated as the game progresses.
