Dr. Mundo Skin Idea
Pre-Injection Mundo. He appears as a lab-nerd in a white lab coat etc instead of his monstrous form. He turns into the Dr. Mundo we all know and love only during his ult timer, think Jekyll and Hyde. So Mundo die-hards get mundo during his ult, otherwise the skin is a human in a lab coat etc...
Voice - His new spoken phrases can mention how Noxus has recruited him away from the "idiots" or "fascists" of Zaun since Zaun. He can also be muttering about the ingredients he uses or mumbling about neural pathways etc...
Q - Hurl a beaker or syringe containing a slowing concoction, instead of cleaver (glass break or dart-stick sound effect on hit) W- Throws down or pours out a flammable or gaseous beaker for the damage aura instead of the fire ring. (glass breaking or glug-glug sound effect) E- Whatever animation for the buff you like, change or not. R- Slams a syringe into himself - normal Mundo briefly returns!
The skin could be called Lab Tech Mundo or Med School Mundo or Pre-Injection Mundo etc....
Please do this, I love Mundo and his speaking voice and phrases just dont match how really evil his lore is!
