Yeah, I've tried him too
Very cool character, but I think 2 small things should be edited
1. Invisibility - maybe I too used to how MK Reptile's works, but it feels strange on how it doesn't disappears on receiving hit. If you will not make it disappear on hit you could make it like Mad Predator by Sergeus have - not fully transparent. Second option maybe even better then first.
2. Shoulder cannon - it could use meter with overheat feature, like it was in game and some avp mugen chars have.
