Skin Concept: Dragon Trainer Rumble
We already have two dragon trainers, both of which are yordles. Lulu has a hatchling, Trist has a young/child, why not give rumble a teen/adult dragon to ride. Flame spitter would just be ... well, basically the same, since dragons breathe fire. Maybe he hold the harpoon gun himself for that one. Scrap shield be made of shed scales, or just a heat orb, and his ultimate be magma balls, kind of like trist's explosive shot. Ontop of that, his passive could make the dragon's hands catch fire as it goes to smack the enemy.
This skin, if made, would probably become the next ultimate skin, despite me not really wanting to dish out 20 bucks for a skin. The model and animations would have to have a huge update for this to work. https://40.media.tumblr.com/885b29070fe32f7e62aaed695cb8553a/tumblr_nxxfov3zgh1r7fj2go1_500.jpg Good rendering of concept, wish i knew who the artist was though, They deserve all the credit. I will remove the image if the artist wishes.
