Speedwagon is one of the main characters in the Milk in the Coca Cola Glass series. He lives with Jonathan Joestar and their pets, Danny and Diego. He was part of the beginning of the series when he and Jonathan went to the 7/11 to buy doughnuts. Speedwagon's "stand" is the Ogre Street Shits which are just Kempo Master and Tattoo spawned out of nowhere.

Speedwagon is the "real" Speedwagon, as he has multiple clones: FTM Lesbian Speedwagon, Crusty Eyepatch Old Speedwagon, Speedtaur, Rare Albino Speedwagon, Mermaid Speedwagon, MTF Speedwagon, and Screamwagon.

Personality
Speedwagon's personality is basically the same as he is in JJBA but slightly more impeccable because the RP makes no sense to begin with. He yells and screams a lot, and also swears, and he hates the crusty people or the ones that spam fetishes. He is slightly obsessed with Jonathan, and follows him everywhere. Speedwagon often threatens to kill anyone crusty or being annoying with a hat.
