6. Bat-Cow
(Batman, DC Comics)
Grant Morrison, you are just the best. Originally, this spot was supposed to go to Ace the Bat-Hound, but I didn't feel the comics version of the character had enough to him to generate an interesting entry. And then I remembered Bat-Cow, and I realized who really deserved the spot.
Introduced in the first issue of the new 52 reboot of Batman Incorporated, Bat-Cow was just a typical cow living in a slaughterhouse and marked for death, until Batman and Robin burst in to investigate. Damien Wayne, aka Robin V suggested that they keep the cow. And they did, christening it Bat-Cow.
Unfortunately, a later mission revealed the cow to be irradiated. Eventually the problem was solved, and Bat-Cow remained a part of the bat family through Damien's death. Batman gave him a cape and let him roam on a Wayne Enterprises dairy farm.
After a crossover with Infinity Man and the Forever People, Bat-Cow retreated into relative obscurity. I mean, he popped up in the third Lego Batman game, but then, so did I think literally every dc character. Heck, even"¦ um"¦ hang on. I was trying to finish that joke by naming an even more obscure DC character, but Bat-Cow is THE most obscure DC character. You win this round, reality.
