Razu
RobotnikRazu appears to be an aggressive young lady who embraces some minor masculine traits.
Don't be fooled, however, as her hostility is a facade: She is actually a very supportive, passionate, and loving girl.
She takes up this deceptive wrathful personality so people won't dare mess with her or her friends.
Still, it's best you don't do anything to her friends, especially her blue-haired companion--otherwise her anger will become very real.
