I was going to go with Frost or something but this makes more sense. She’s like both Shadow and Metal Sonic. She’s a genetically altered clone of Blaze made by Eggman Nega. Instead of just giving her fire or ice or some other element her power is “cold fire”. Look up super-cooled plasma. It’s neat stuff and a concept I’m also using in BIOWEAPON Eclipse. Green was the only color that made sense thru process of elimination and it’s the invert of violet. Blue in place of magenta. Violet eyes as that’s the compliment of yellow. She’s a bit chaotic personality wise.
