At Botcon2015 I got the four wasps exclusives and they came with bios that said they were basically all just exo-suits and that the little gun guys they came with were the pilots... but these toys don't have cockpits, so I did some quick sketches of them, and gave them all personalities. The wasps are all part of Waspinator's hive (nest?), the large ones being adults and the small one, naturally, being the young.
This guy was called "Mudfighter", but I thought he looked like Beast Wars Buzzsaw, so I called him that.
He thinks he's Waspinator's second in command. He has a heroic personality, despite still being a Predacon.
