Bella of the Icicles
Flex: "She has black hair. That's all she's had for physical description so far"
Samarkana: "I got this"
And that's how we learned Bella is mischievous, digs chains, probably drives monster trucks and other vehicles you can put chains and other implements on, and loves to run over anyone that gets her too angry. There's a fair chance she has a boyfriend with similar interests, potentially including crushing each other in their spare time.
The blue highlights are mostly because of the team of The Icicles. She's been known to favor deep reds and purples on occasion.
Note - the lipstick smear is a mistake on my part. She knows how to apply it
