Awesome Music: The title theme, fittingly sung in an Army Chorus harmony style, is so awesome it could give anyone a case of Patriotic Fervor for weeks on end as it repeatedly cycles through their head.
"The Inside Scoop" & "Nephew of Neugog": Dr. Hieronymous Neugog was a wannabe Mad Scientist before a freak accident transformed him into a brain-eating monstrosity. Neugog sucks out the minds of many unfortunate people who get in his way, even people Neugog admits have no valuable knowledge to him whatsoever, and at the end of his first episode plans to attack a convention filled with hundreds of brilliant minds for him to snack upon. Even when a rival brain-eater forces Neugog to team up with the heroes, Neugog betrays them at his earliest convenience and attempts to take all the minds his rival has devoured for himself.
"The Champ": Po the Obliterator is a posturing brute out to prove himself as the best fighter in the universe. Po travels to a world and threatens to destroy it unless its best fighter challenges him to a duel. After invariably defeating his opponent through cheating if need be, Po takes his fallen foe as a frozen trophy, kept in containers lining his ship for him to mock as he so pleases. Arriving on Earth and forcing the Big Guy into combat, Po flies into a rage when Rusty saves the Big Guy armor from Po's captivity, prompting Po to rampage on Robopolis and threaten to destroy the whole planet. Even when beaten down by Big Guy and showed mercy, Po feigns remorse only to try to wipe out Earth anyway "just for laughs" out of spite at being defeated.
Fridge Logic: How do computer graphics suck to the extent shown in Little Boy Robot Lost and Bicameral Mind, when they have fully functioning, Turing Test passing AI?
Nightmare Fuel: Neugog, full stop. A giant green arachnid-like being with a human shaped head, exposed brain, two mouths full of sharp teeth(the lower of which expels a tentacle sucker that sucks on the brains of the people he attacks, leaving them near catatonic and unable to even speak properly). His abilities to telepathically control humans makes him a threat too, as he controls Lt.Hunter while he's inside the Big Guy suit, forcing him to practically serve Dr.Slate to him on a silver platter, though Rusty rescues her without realizing what's happening.
In "Birthday Bash", Rusty takes an alien device from the labs to give as a birthday present. However, the device binds things together against all laws of physics , which we see from two scientists fused together. Lt.Hunter's sister is fused into a wall of her house, left an inanimate statue, unable to move. At the end of the episode, the two aliens attempting to retrieve the tech are practically melted together.
, fittingly sung in an Army Chorus harmony style, is so awesome it could give anyone a case of Patriotic Fervor for weeks on end as it repeatedly cycles through their head.
