Despite his age as a teen he has shown to have great strength and speed as well as a skilled fighter.

​Personality
Nisemono is an embodiment of the stereotypical megalomaniac: bloodthirsty, insane, selfish, vengeful and relentless.

He hates anyone who challenges, impedes, or otherwise wrongs him, holding grudges long after the fact - in some cases, this can even become an almost pathological hatred against them.

After Nisemono had assumed the identity of the Shredder, his megalomania became even stronger, to the point of calling himself the "one true Shredder".
