Data Pair is something I definitely ship :D There's one story in my doujinshi collection where Bunta munches on Jackal's head and Sanada's hand and then Niou pretends to be Jackal, but Bunta rejects him and goes with the real Jackal. (There's also a story where Kaidou really is a talking snake and it ends with him swallowing Tezuka whole XD.)

Ooooh I like delinquent/tough guy and big softie type pairings like that.
