I think it goes
>Original form was Regulusmon without the scarf, or possibly GulusGammon without the cloak (if Regulusmon didn't exist in the original storyline)
>Sorties to fight not-Galactus when he attacks his planet, loses and watches all his loved ones die
>Escapes to Earth but has degenerated to GulusGammamon, and also gone insane with grief
>Attacks everyone around him while yelling about how Might Makes Right, becoming known as the Shikkoku no Haou
>One day someone stronger shows up and beats him down to Gammamon
>Attempts to continue but is so weak now that he gets beaten up by cannon fodder, mindbreaking him and causing him to regress to infancy
>Hokuto befriends him and gives him a scarf, which becomes integrated into his full Gulus line but not his Gammamon line because he needs his full mental faculties to register how meaningful it was to him
