His head resembles soft serve ice cream (hence his name). He was the guardian of the "Jet Black Room" of C-Block's "Aitsuhage Tower" (some fans think he was the vice commander). Softon uses "Babiron (Babylon) Shinken" (in the English dub, he fights by channeling the power of "the Goddess Blabs-A-Lot," a not-too-obvious pun: Blabs-A-Lot = Babble on = Babylon).

Perhaps not coincidentally, the shape of his head also resembles the typical manga depiction of poop. In promotional color artwork for the manga, his head is colored brown, whereas in the anime, it is colored pink (which is not a U.S. TV edit). It is later revealed that this isn't his real face but a mask used to control his powers, similar to Gasser's collar. He is the only non-human looking character to not fuse with Bobobo (probably because he is too big to get in any of his openings).

He allies with Bo-BoBo's team after Beauty is kidnapped, but doesn't officially join until the battle with Halekulani. In many episodes, Softon's "poop" jokes are directly copied from the manga, but put in the context of ice cream. Later, against Lambada, Softon reveals he was given the power of the Black Sun by J and combines it with Goddess Blabs-A-Lot. During a battle in the Hair Kingdom against a Babylon assassin, it is finally revealed that he is Beauty's older brother, explaining the connection he consistently has to her. He is also the mascot of an ice cream shop.
