OK K.O.! is an American animated series that airs on Cartoon Network. It is about a boy named K.O. who wants to be a hero, and he's friends with a ninja girl who works at the front counter and her alien co-worker, and they fight robots together. The robots (and their creator) are all hellbent on destroying the plaza (where the series takes place), they dislike defeat and disappointing their creator (who is also their father).

I don't think my description was too good, so here's a Wikipedia article on it.
