Major Spoilers ahead!!
Wow, the episode ''The Big Reveal'', it was exactly that i wanted to happen.
So yes, Laserblast is really K.O's father (been on that theory for almost 2 years by the way), also Laserblast is also Professor Venomous, and yeap Carol didn't take it well that she was in love with a handsome hero who was a villain too, we know K.O will never be like him, but he has the powers of a villain, and i really hope he'll be alright.
