Gabe, the Homicidal Maniac

Overview
Gabe, the Homicidal Maniac is a Transgabe originally from Bismark, North Dakota. While he originally had the benign life goal to be a rock star, his inability to sing led to him living up to his name and leading his Killer Krew in a war against the Council of Transgrabes and Council of Transgabes, in which his weapon was the children's card game of Duel Monsters.

Massacre of the Transgabes
On October 31st, 2015, Gabe, the Homicidal Maniac led his Killer Krew to The Gnarly Root in Parker, Colorado, where the Council of the Transgrabes was meeting. Angry over them having him fired from his band, The Dark Mammoths, and replaced with Gabe Hults, Gabe, the Homicidal Maniac announced his intentions to kill every last Transgabe present on Earth.

Duel with Grabe the Wise
While sending the members of his Killer Krew after many of the Transgrabes, Grabe the Wise moved to stop Gabe, the Homicidal Maniac, reasoning that his wisdom would allow him to prevail in a card game, failing to realize that card games are based around ancient magic and prophecies, not something as silly as wisdom. Despite using his Hyper Smart Philosopher Stoned Teenager's effect to make it immune to destruction by battle or card effect while being unable to be tributed, Gabe unveiled his trump card, JIHADI Crying Sister, who negated Stoned Teenager's effects and dealt their combined attack in damage to Grabe the Wise. Having lost a card game, Gabe now sealed Grabe into a nearby LEGO piece, seemingly killing him.

Duel with Grabe of the Many Fingers
A good friend of Grabe the Wise, Grabe of the Many Fingers, rushed Gabe, the Homicidal Maniac in a foolish attempt at revenge. Grabe of the Many Fingers was weak, and struggled at the most basic Card Game Concepts, meaning he was easy fodder for Gabe, the Homicidal Maniac. Grabe of the Many Fingers used his Fingering cards, normally very strong, to little effect, trying to summon The Fingering Robot, The Fingerer, but Gabe, the Homicidal Maniac managed to summon JIHADI Airplane to make a direct attack on Grabe of the Many Fingers' Life Points, defeating him, and sealing his soul into a used condom.
