She went throught severe redesigns to fix this mistake. But she still doesn't look like a Sonic OC.

Also, Eva has a tiny bit of inspiration from Sonic himself. Which is her inability to swim. But it's not because i thought foxes couldn't swim, she was neglected when she was younger and her dad didn't let her learn how to swim.

Even if her dad stopped treating her poorly, she still refuses to ask to teach her how to swim.

Last time she tried to, she spotted a hostile entity coming towards them then she hit a rock and passed out when she was nearly able to swim.

So yeah, kinda went a bit off-topic :P
