Sneak Peek 'Krypto' on the cover of DC Comics' "Batman Superman" #11, available May 21, 2014, lending some credibility to rumors that 'Superdog' could cameo alongside 'Kal-El, 'Batman', 'Wonder Woman' and 'Lex Luthor' in director Zack Snyder's "Man Of Steel" sequel, "Batman v Superman: Dawn Of Justice".
'The Legion of Super-Pets' currently appear in the "DC Nation Superman 75th Anniversary" short that was screened @ New York Comic Con 2013 and included in the "Man of Steel" DVD release.
Although animal members of "The Legion Of Super-Pets" had appeared in various comic books throughout the years, the super-animals made their official team debut in DC's "Adventure Comics" #293 (February 1962).
The team roster included 'Comet' the 'Super-Horse', 'Streaky' the 'Super-Cat', 'Krypto' the 'Super-Dog', 'Beppo' the 'Super-Monkey' from 'Krypton' and shape-changer 'Proty II'.
Significant appearances include issue #322 (July 1964) when 'Proty II' is initiated onto the team and issue #343 (April 1966), with the 'Super-Pets' helping the 'Legion of Super-Heroes' battle the 'Luck Lords'.
Issue #364 (January 1968) was titled, "The Revolt of the Super-Pets!"
The team rarely appeared after the Silver Age except for 'Krypto' who become a supporting character in various "Superman" comic book titles.
Other versions of the 'Super-Pets' appeared in "DC Super Friends" #14 and on the cover of Marvel Comics' "Not Brand Echh" #7.
DC Super Friends included 'Ace the Bat-Hound'.
Also in Super Friends was the 'Aquaman' octopus 'Topo' and 'Jumpa' the 'Wonder Woman' kangaroo. The group was led by 'Ch'p', a squirrel-like 'Green Lantern', that became the 'inspiration' for Marvel's 'Rocket Racoon' from "Guardians Of The Galaxy".
