* Heimerdoodle* - the savant artist version of Heimerdinger, looking similar to Bob Ross with his brunette afro, but maybe wearing a beret, artists coat, holding a palette in one hand and paint brush in the other instead of his usual wrench. Also, his turrets could be different colors of paint tubes that instead of firing bullets or whatever, they fire big globs of paint at enemies. His ult turret could be a giant paint tube that consists of all 3 colors together (red,blue, and green). The rockets he fires could be very sharp paint brushes or chisels. The only thing I'm concerned of that wouldn't fit this concept is his dialogue.
This idea came to me as I boringly watched pbs at home and saw Bob Ross and thought.. the hair..genius.,Heimy.. yes.
Edit: Just found this idea on the forums from a few years ago but instead of paintball gun turrets they thought of easel turrets.. which I don't see as being able to shoot anything.
