From the Pop Culture Addict, a Top 10 List of the Lamest Superheroes of All Times. For example:
#3. The Legion of the Superpets - In the late 1950s and the early 1960s DC just kind of got weird. They kept introducing all these super intelligent animals with the same superpowers as Superman who all wore red capes. The first was Krypto the Superdog who was sent to earth by Superman's father Jor-El in a test rocket before he sent Superman to make sure it worked alright. Superman and Krypto were reunited on earth when Superman was a teenager and they fought crime together. Next was Beppo the Supermonkey. Beppo had pretty much the same story. Jor-El also sent a monkey to make sure the rocket would work. Everybody knows that comics need a chimp, so Beppo provided comic relief by wearing a Superman costume. The next was Streaky the Supercat. Now Streaky wasn't sent from Krypton in a rocket but was infected by white Kryptonite which gave earth animals superpowers. Finally came Comet the Superhorse. Comet was an alien horse that was really a man who had a curse put on him by some scorned goddess (or something like that) and turned human once a year and romanced Supergirl, but the rest of the year was nothing but her pet horse (holy bestiality Batman!). Anyways, these animals eventually joined forces to become the Legion of the Superpets. I swear to god.
