Ink-Oct, or "Inky" for short, she's a cephalopod-based super villain.. or super hero? I do not know, but I would think she goes in and out of phases. Also, she should totally have a squid sister.
Sorry about the somewhat generic design, I really wanted to get some super hero/villain stuff out before the date was done.
Octo-Ink's kid sister, she's squid based. She's got no arms, but her hair transitions into those long Squid tentacles and she can use those to, you know, rob a bank or rip your face from your head.... or to save a baby from a runaway carriage!
