Monstroso was a 13 foot tall supervillain who served as the attorney for The Council of 13. He had many affiliations and was targeted by both the O.S.I. and S.P.H.I.N.X.
Monstroso was distinguishable by his massive size, his expensive suits, his goatee, and his GCI ring. When engaged in Guild business he would don a red devil hood with horns. He was notorious for his penchant to double-cross and for offering his cigars to his clients.
Monstroso had a personal army of henchmen, The Associates, who wore red hoods with an embroidered 'M' on the front. Some of his Associates were former Monarch henchmen who joined up after The Monarch went to prison.
Monstroso tried to double-cross The Monarch by seizing both his archenemy Rusty Venture's property as well as his own, all through legal means.[1] He was prevented by Henchman 21 and Brock Samson, who physically confronted Monstroso and violently forced him to tear up his agreement with The Monarch.
After his ordeal with Henchman 21 and Brock Samson, Monstroso was dying of heart failure and made a deal with The Investors to prevent his death via a surgery.[2] The Investors kidnapped Billy Quizboy to operate Monstroso's surgery by replacing his failing heart with King Gorilla's, who was released from prison via another deal. Monstroso returned Billy's favor by providing him with legitimate credentials that officially recognized him as a doctor, as well as an evening with three prostitutes dressed as vampires. After the surgery, Monstroso was captured by S.P.H.I.N.X. However, Monstroso escaped with the help of his lover, Molotov Cocktease.[3]
In the episode O.S.I. Love You, he along with Molotov were recaptured by O.S.I. and brought to the O.S.I. Hover-Quarters. Monstroso was interrogated by Brock and freely told him everything he knew about the Guild, as he claimed to be "as good as dead" anyway since the Guild would be coming for him. When Molotov escaped and caused O.S.I. personnel to be distracted, Monstroso's fears came true. The Investors appeared before him and killed him by phasing him out of the Hover-Quarters, dropping him to his death. Brock was the last person who saw Monstroso, but he did not see The Investors. The O.S.I. listed Monstroso as officially "Missing".
Monstroso runs Mammoth Corp., a "legitimately traded business" that covers his illicit activities.[1] There are numerous diplomas and certificates decorating the walls of his Mammoth Corp. office, including:
Ecole du Mal de Paris - Post Graduate Diploma in Hate Management
Guild Dragons of Industry - Titan in First Standing
The Stockholm Institute of Human Dominance
Trivia
Monstroso shares a number of similarities with Marvel Comics villain The Kingpin, including his monstrous size and being a businessman running a criminal empire. He also shares some traits with Anton LaVey, founder of the Church of Satan, including his facial hair, devil hood, and general devil motif.
Monstroso is very similar to the Marvel Comics supervillain Imus Champion, a nine-foot tall criminal mastermind with an MBA, superhuman strength, and vast wealth from his various business ventures. Despite his massive stature, he was laid low by a supposedly incurable health condition and used his considerable resources to find an alternative cure.
A photo of Monstroso at a party was printed in the tell-all biography The Flight of The Monarch. According to Dr. Girlfriend there were "like, five of us" sitting on his huge lap.[4]
