Couple of animals I have been looking at:
Spiders - Black Widow
The Spherical body is very interesting and that red marking inspires me to create a logo for the characters to wear. A logo that shows exactly who each character is and acts like.
I wanted to keep the scorpion in mind because I use it as a reminder that a character doesn't need hands or fingers to get a job done. Those pincers could be interesting for a weapon...?
