even when he is at their mercy. He tells everyone who will listen this secret of his super powers. When the series was syndicated in the 1980s and 1990s, the scenes of him taking his energy pill were edited out. In the recent release Underdog: The Ultimate Collection, the word "Energy" was replaced with "Vitamin". Underdog is shown to have incredible superhuman powers. However, the number and scope of his superpowers are inconsistent from episode to episode, being subject not only to the conventions of superhero comics, but also to the conventions of humorous cartoons. In one episode, he easily moved planets, safely butting against them with his rear end. In another episode, his Super Energy Pill, diluted billions of times when added to a city's water system, was capable of giving normal humans who drank the water enough strength to easily bend thick steel bars. Among his many powers shown on the show are: super strength, super speed, supersonic flight, physical invulnerability, X-ray vision, super breath, cosmic vision, atomic breath, atomizing eyes, heat vision, ultrasonic hearing, a supersonic high-pitch hi-fi voice and a great calculating brain.
