Professor Starr

Professor Starr is a character from Phineas and Ferb and is a reoccurring antagonist in Knights of the Multiverse Season 1. He's a member of the League of Scientific Renegades well known for his rivalry with Dr. Symphony and is the creator of Lime, Cherry and Bloodberry.

Personality
Starr is a rather egotistical scientist, believing that he knows what's best and he doesn't need to listen to his supposed superiors. He's also the type that doesn't really care about the well-being of his Droids, only really showing any concern for them whenever they display some sort of great improvement in their power. He's the type to simply sit back and watch as his experiment unfolds.

Skills & Equipment

 * Skills in Robotics
 * Energy Manipulation

Lime, Cherry, & Bloodberry
Like most of his contemporaries in the organization, Starr cares nothing for his Droids, only seeing them as a test bed to see his theory on which of their body types are the most powerful. This is best exemplified by his response to Lime deserting him and Bloodberry being destroyed: all it proved to him that the child-type Droid is too easy to manipulate, and the adult-type Droid proved to be too eccentric.

Crystal Knights
Unlike his associates in the organization, Starr doesn't really seem to pay the Crystal Knights much mind, since he sees their battles with the organization's Droids as a way for his Droids' powers.
