Custer Kurtz

Charles "Custer" Kurtz is the main antagonist of the fanfiction Hellboy vs Demonic Toys. 
==Role and Character ==
Kurtz serves as the main antagonist of Hellboy vs Demonic Toys. He is under alignment and serving for The Demon King, but he is on a mission of his own to find and kill Hellboy, due to past event. 
In the in progress Fanfiction, Custer Kurtz: Origins, it's revealed Kurtz is bullied constantly at school, which lead to his evil life of a serial killer, after he excruciatingly murdered them. 
He gains control of the Demonic Toys after The Kid lends the responsibility to him. When each toy gets killed off one by one;
Jack Attack: Shot by Liz Sherman
Baby Oopsie Daisy: Shot twice by Hellboy
Grizzly Teddy: Face Burned Off
Mr. Static: Melted in Garbage Fire
Kurtz eventually is killed by Hellboy and Liz.
Sequel 
He returns in Hellboy vs Demonic Toys II, which is still in progress.
Kurtz is now even more pissed that he couldn't kill Hellboy and drives him to the point of just simply bullying Hellboy. He is also joined by a demon called Despair, who despite being far better at torturing Hellboy, and taking both to drive him to Emotional Breakout, Kurtz still admires Despair.
==Weapons and Powers==
Kurtz is actually very smart, and was able to develop many weapons, including a near permanent claw on his index finger, which cuts through nearly anything, including steel and metal. 
Originally, Kurtz and Despair could merge into one to become "The Devil" but Despair started being able to just turn into a devil. 
Kurtz used to be able to switch between Human and Demon after his first resurrection in the 1980's. Now, that power is defunct, as he just reincarnated as a demon.
==Personality==
Kurtz is a sadist in both stories. The traits are explained in the infobox.
==Theory==
Kurtz might be depressed. This was never claimed in the fanfiction, but the fact that he is very satisfied in anyone he doesn't like in danger is a huge red flag.
