The Angel of Death Project is a experimental site by reeferlungss, It usually takes to an alternative universe where Angel is an actual Angel of Death, who brings death/murder in Jesoos' name.
Angel is a minor recurring character in The Nutshack (2007-2011), He's basically made to be a "stereotypical macho latino character". Angel's usually seen working in DC Customs with his friend Ed and they're mostly seen together.
no.
Because I do believe there must be some lore about him, In The Nutshack, Season 2 Episode 2 (El Bombadero), It is seen shown that Angel is the literal Angel of Death, Hence the title of this site.
In some parts, yes, but when it comes to theories it's not. I don't expect some seriousness though, since this site is centered about a character from a meme show...
