Since this thread I have watched the entire supernatural series in hopes of seeing the epicness that is someone crazy stronger than goku. I found "gods" and these "archangels" and "higher beings" losing to boys raised as humans. I also haven't seen half of what is depicted in that database for lucifer and michael and if I have it was in no way the same as depicted because it was not very impressive. Goku should lol stomp here.
The boy was a Damien type character. Son of the devil style. Arguable on par with the likes of Michael and Lucifer.
If you watched the show, then you'd know the only way to kill an angel is to have the angel-stake or be the level of power as Michael and Lucifer. Loki/Gabriel pretended to be dead many times but kept coming back until...well you know what happened to him.
