[Skinconcept] Battlecast Jinx
Ok, not an artist so no picture to go with this, just a written description.
Jinx, being as crazy as she is and also from zaun, seems one of the first people to actually volunteer for the battlecast conversion if it means more boom. However, in keeping with her anarchic attitudes, the overall design should look 'unfinished' and/or 'battle damaged' like her hair looking like cut cables with sparks coming from the ends.
What made me think about it is her working title 'the walking armory girl' and how you could switch up the animations. Specifically, I'd have fish bones be her right arm pow pow be a left arm. As in, when you press q, one arm changes to the weapon while the other arm holds it (the whole left arm looking like a rocket launcher while the forearm of the left becomes the chain gun, but each changes to look mostly like a normal hand while the other arm is changed). To play up an anime trope and play on the 'flat chest' gag, she could launch the chompers from her chest. Zap could come from the eyes while the super megadeath rocket could fire from her back, with the rocket's warhead actually bearing her robotic face.
Any thoughts?
