So I'm not the best drawer but I figured I would attempt to draw Ratchet holoform and Mika and then a Chibi Bulkeah miko one with his true form in the corner and Soundwave annoyed in the other... so here's my scrappy attempt at drawing. No flames plz I'm noob with drawing Transformers....

Mika and Ratchet

Miko and Bulk

I don't have many colored markers so I did my best....
