Krang is known for being a brilliant general and scientist, having designed countless weapons, including his well known android body. He is a cold, cunning, manipulative and somewhat a sadist, as he claims that he enjoys watching "people and animals suffer". Despite his frail appearance, many other villains fear Krang, including Shredder, who denies this, Bebop, Rocksteady, and Baxter.

Even as a brain-like alien entity that typically occupies and operates within a mechanized suit or mobile Android body to interact and fight on a physical level.

He was finishing working in the last updates for his Krangdroid armada, he turned the android vessel as a prisoner was brought.

"Oh good, it seems that there are competent mongrels in this wretched planet..." He sneered from within the open cavity of his mechanical suit.

"I heard from Baxter, you understand Utrom technology...let us see..if that is so.." Krang glared intensively at the prisoner.
