This is her design by her voice provider. She is meant to be latina like her.
PowerFX had released their own design, which was admittedly hideous.
Misha, the voice provider, introduced Ruby with the ugly design at AX. She had no idea that this was what Ruby was going to look like. The contract that Misha and the programmer, Syo, had allegedly signed with their contact to PowerFX, demanded that Ruby's design be chosen by Misha. Their contact, Anders,
allegedly lied about passing on that design.
Because of the #saveruby campaign, where fans harassed PFX's CEO and called him a racist, Ruby's design was changed back.
Also Misha is an entitled bitch.
