Scintilla The Hedgehog: The sister of Spark and she uses white lightning. Also small update from last one.
Negative Mar The Dog: Or Evil Mar.
Nightmare (Hedgehog maybe): Powers are like Scarecrow from the Batman comic book.
Metal F.R.O. Mk XIII: Much better update.

I'll make refs and bios for these characters later. Also all the characters aren't completely finished.
