8) Beppo the Super-Monkey

Beppo, on the other hand, is both from Krypton and a monkey, because monkeys evolved there exactly as they had evolved on Earth (as revealed in 1959’s Superboy #76). Also as on Earth, Kryptonians used them as test subjects—like, say, if a scientist was building a rocket to shoot his infant son into space before the planet blew up. Beppo was the lucky test subject who survived the first test trip back, and even more luckily secretly stowed away in baby Kal-El’s ship before it blasted off. He escaped unnoticed upon arrival, and gained superpowers just like Superman, thanks to Earth’s yellow sun. Eventually, he rediscovered his travel companion as a child and started secretly messing with little Clark and various stuff on the Kent farm while Clark got all the blame, which is quite funny. However, he revealed his more heroic side as a founding member of the Legion of Super-Pets.
