Senkuu is a genius with a vast amount of scientific knowledge. He is able to invent various kinds of tools and gadgets in a short amount of time with ease. As a child, he designed and built a functioning miniature rocket ship. Senkuu also possesses an analytical mind, being able to correctly discern the situation he is in. Even in his pre-teens, he was intelligent and sharp-minded enough to create advanced machines.

Senkuu's physical abilities are very low and he would lose against someone like Kohaku in a brawl, something he himself admits.

In "Village Games Arc" Senku unintentionally won and married Ruri, but divorced immediately afterwards.
