Dracula (mentioned); The Angry Video Game Nerd Adventures (physically)
Frederic S. "Fred" Fuchs (spelled Fred Fucks in Angry Video Game Nerd Adventures) is a Canadian-American Film producer best known for his producing Bram Stoker's Dracula and The Godfather Part III.
AVGN name pronunciation
In the Dracula episode (episode 57), Fuchs first "appears" when the Nerd is narrating over the credits rolling in the SNES video game Bram Stoker's Dracula.
At the video mark of 9:42, when the Nerd begins to read such credits, he notices and is baffled by the fact that a man who produced the game was named "Fred Fuchs" as one of the only ways to pronounce it is the vulgar term, "Fred Fucks". James Rolfe could barely get through acting out the scene of the Nerd starbound at Fred's surname without bursting out laughing.
In episode 84, starting at 8:27, Fred is mentioned in the episode when the Nerd is talking about the non-responsive controls in the game, he says that maybe it was "Fred Fucks" that designed the controls for the ice skating game.
In episode 99 at the 16:09 mark of this episode, The Nerd is making a negative commenting on a popup window of an 8-bit photo of a programmer's face saying "I wish it was Fred Fucks!"
In episode 107 at the 4:31 mark, the Nerd is commenting about the cinema area in the game Total Recall. He notes that the movie shown there is just the game credits and than he says "I miss Fred Fucks!"
The Town With No Name
When an in-game character is shot and killed, the Nerd makes a comment on the excessive amount of blood, in which The Nerd replies with "For Fred Fuchs sake!"
Mister Fuchs himself (under the name "Fred Fucks", presumably to avoid defamation) appears as the boss in Laughin' Jokin' Numbnuts, the final boss of the entire game and as the main antagonist. He is the very programmer of Game Land and purposely sucked the Nerd and his friends into said Game Land just to show them what it feels like to be in a shitty game.
There, after the Nerd beats all that is behind him, Fred, who was simply an anonymous voice at the time, mocks and is slightly impressed by the Nerd's determination, skill, and will to get as far as he did. When the programmer reveals himself, the two eject into battle, with Fred donning a handless jetpack, flying around the arena.
Fred's attacks include spewing fire balls out of his bare hands, spawning chained maces swing about on his crotch (which he refers to them as his "balls"), and defecating, using his turds like dropped bombs, thanks to his uncontrollable bowels. After the player finally evades all of these attacks and pumps enough Nintendo Zapper lead into Fred, he is "killed" and Game Land falls apart due to the death of its programmer.
His appearance consists of short and spiky brown hair, a beard, jeans, glasses, and a T-shirt with "FF" on it.
