One angry mother...

...you thought I was gonna drop the F-bomb here, didn't you?

But, I'd like to all to meet the ghost of the seas herself.
She is Sushi's sister.
Mearadey's mother.
The woman who could tame a levithan.
Eight feet tall and solid whoopass.
Hasn't spoken scorpanidae for years.
SHE IS TSUBELLA.

Hehehehe. Yeah, I had fun designing her. Her eyes look so odd because she's completely blind, but her hearing is still quite sharp (Her husband is deaf, though). Both her and Sushi (And Mearadey) are from a nomadic tribe that was allmost completely wiped out, but was known for one rather odd quirk. They're born small and weak...but...well...as you can tell from both her and her brother, they grow to be massive beasts of scorpanidae. Her poison is also a crippling one, attacking the nervous system. A small dose will numb your arm for days. A large dose will numb your brain. Premenantly.
After the Marrkarr beast destroyed her family's farm, she assumed Sushi dead due to his massive head injuries, and fled, eventually wandering far enough that she couldn't be found, and eventually joined with a distant, barbaric, nomadic clan that didn't even speak scorpanidae, meeting her husband, and having Mearadey.

Who, sadly enough- SPOILER -suffered traumatic head injuries when she got too close to a boat propeller, and suffers from amnesia.

And god-damn, I love her. Partially because she's totally crazy, and then suddenly all sweet and kind and maternal, and partially because she controlls gorram levithians. And uses the massive eel-beasts to attack stuff. You know...when she's not tearing apart sharks with her bare hands.

...Did I mention I love her? XD
