This bring a tiny bit of conflict in Episode 21, where Joey and Psy are led to believe that Lina's brother Will kidnapped Holly. On one hand, Joey admits that he would hurt anyone who hurts Holly, but Joey doesn't want to indirectly hurt Lina either.
Disguised in Drag: Invoked when he (or rather, his older sister insists that) he needs to sneak into a hospital to talk to one of the patients. Interestingly enough, he didn't have to alter his appearance much; he just needed to put on a dress. Which leads us to...
Dude Looks Like a Lady: He greatly admires his father and strives to be like him. Alas, genetics being the fickle bitch that it is, he favors his mother instead. Greatly favors. As in, looks exactly like her.
Wrong Genre Savvy: The justification for his evading the government's attempts at capturing him and Heroman was that it was clear that the media was being manipulated into making them look like the bad guys, and the fear that he'd wind up as an experiment alongside Heroman. Agent Hughes scolds him for the latter, saying that it was a silly assumption.

The titular character and Joey's Robot Buddy who comes to life after getting hit by lightning.
Handicapped Badass: Being unable to walk properly does not seem to impede him from riding a skateboard, assisting the professor in his plans, and even kicking ass right alongside Joey with a sweetass guitar.
All Guys Want Cheerleaders: A rare inversion: it's our cheerleader who really wants the average, "nerdy/loser" hero, much to her brother's chagrin — Lina is more to take the initiative on her feelings, while Joey's a bit more subtle and reserved about it.
Magic Skirt: Very brief panty shot during her introduction in the manga, but played straight in the anime where we never get a single panty shot. She gets several more in volume two of the manga, later on along with most of the rest of the cheerleading squad.
Tag Along Kid: Insists on following Joey and friends into the city during the Center City invasion arc, despite being the only one to not join in the fight against the leader of the Skrugg. This fact allows her to avoid becoming The Load, however.
The science teacher at Joey's school whose successful contact with aliens led to the Skrugg attack on Central City.
The Atoner: Mild case. He feels it's his responsibility to help Joey fight the Skrugg. After all, he told them where Earth was in the first place. This being a light-hearted kids' show, he doesn't spend much time angsting over it.
Break the Haughty: Dear Lord. Not only does he pretty much lose everything he's ever had in a moment of jealous spite, but all the power he's gained hasn't prevented the Skrugg from doing one damned thing.
Hidden Depths: Yes, he bullies Joey for seemingly no reason, And That's Terrible. But at the same time, he truly does bear sincere love for his sister, and really only wants to protect her and be her hero. He is also revealed to have a strong sense of the responsibility when he stepped down as Captain of the football team, not considering himself worthy after he indirectly caused Psy's disability.
Refused by the Call: He likes to insist that he's the hero. In the manga he attempts to prove himself both by assaulting the Skrugg three separate times and fails each time before learning his lesson. In the anime he fails only once and winds up getting kidnapped and brainwashed by the Skrugg as a result.
Dangerously Genre Savvy: In a series filled with Dangerously Genre Savvy antagonists, he takes the cake, starting with little things like failing to ignore the big nasty robot chewing through his forces, and going all the way up to faking an obvious weak spot in his Eldritch Abomination form in order to lure Heroman into a trap.
Disc One Final Boss: Subverted - he got taken out within the first nine episodes, and then returned in style for the series climax.
