Spike the Devilman was a somewhat interesting antagonist in the original Dragon Ball anime. The strongest of the living fighters for Fortune Teller Baba.

Spike has a very interesting power, which is a beam that uses negative energy against people. Which theoretically would make him able to kill anybody with an evil heart. Which poses the question if he could actually have done it to King Piccolo, Raditz, Napa and Vegeta, Frieza or Majin Buu?

But when Goku was hit with it, nothing happens because he’s a good boy.

And Spike is absolutely flabbergasted and is soon outmatched.
