I did know the Columns games had characters. The picture actually missed some nameless characters out. Such as the protagonist and Surhands minions from Super COlumns and the Pyramid inhabitants from Columns III.
Still nice to know that someone in sega still acknowledge Columns had lore.
Yeah, I think because they are only showing one character from each title.
(exception for Columns III and Columns Crowns)
Still missing Sakura Wars and Ozamu Tezuka Columns, but that's understandable.
