Starline's no joke. He's Robotnik's right hand man, and he knows it. Starline is also a fellow scientist, but where Eggman shines in technology, Starline flourishes in chemistry and biological innovation. He won't step out of line with Eggman, but he can't deny he wants his own spotlight someday -- his own statues and posters. Try as he might, he too has an ego, and that may very well get in his own way.

Voice Desc:

Taking some heavy inspiration from characters like Kilgrave (Jessica Jones), Herbert West (Re-Animator), with some dabbles of Poison Ivy and Mr. Freeze (DC Comics) and a dash of Wayne Salinzki (Honey, I Shrunk The Kids), He's definitely a scientist hell-bent on making his mark, so he carries himself quite high, and crumbles when he fails.

(even though his accent is listed as british, i'm open to non-british takes as well.)
