* Dexter's dad. When he gets serious, he gets so goddamn '''EPIC.'''
** Special mention goes to the career day episode. To sum it up, Dexter's school is having a career day and all the other kids are talking about how cool their parents' jobs are. Dexter has no idea what his dad does, so he tells everyone that his dad is a government scientist, which the other kids think is cool. Dexter creates a fake dad in his lab, but when he actually brings this dad to school, Dexter's classmates don't like him. Dexter's real dad (whom Dexter didn't tell about the career day, but he knew about it from a memo in the mail) sees that Dexter's getting a very poor reception. Dad finally reveals what his job is: a professional motorcycle stuntman.
* Dexter's mom's {{badass}} {{catfight}} in "A Mom Cartoon".
* Dexter's entrance into "Ego Trip"... awesome.
** Badass Future Dexter. Period.
* When Dexter learns that pirates kidnapped his sister (they believed she was a mermaid due to her swimsuit), he goes straight to the pirate ship and reveals his GiantMecha, which he had intended to keep secret, and then starts to literally swab the deck with them.
** Dee Dee calling sea anatomies to turn Wet Willie into dust.
** The entire sea battle, really. Features giant crab-like mechs, cannon-loaded ships, dolphins, whales, [[StuffBlowingUp explosions,]] etc.
* Anytime that Dexter's BadassFamily unites. If "[[CrowningMusicOfAwesome Go, Dexter Family, Go!]]" starts playing, prepare for awesomeness to ensue.
** In the episode, "Go, Dexter Family, Go!", when Dexter and his family are abducted by aliens, Dexter screams, "Mom! Help!" [[MamaBear Her brain switches to Mom mode and she breaks free of her chains.]]
* Monkey impressing a pro-wrestling alien named [[Wrestling/RandySavage Rasslor]] by never giving up, even after Rasslor had destroyed the rest of the Justice Friends and refused to fight Monkey, thinking he was too weak. Also doubles as a CrowningMomentOfHeartwarming.
-->'''Rasslor''': Incredible. I could crush your body, I could smash your bones, but I could NEVER break your spirit.
* The entirety of "Last But Not Beast", while it certainly is a spoof of the anime genre and {{Kaiju}} films. It was still ''really'' cool watching Dexter and his ''entire'' family being totally kick-ass awesome!
** Watch Earth's forces kick ass was awesome as well. Everyone from Agent Honeydew's air force to the Justice League to the Commander himself in a little TV that ''fires missiles'' to Monkey. Even that little foreign exchange boy got a moment of awesome.
** The [[GiantRobot Giant Robot's]] [[RuleOfCool didn't hurt either...]]
* Two words:
-->'''Dexter''': '''''MATERNAL COMBAT!!'''''
* The FinalBoss fight between ''four'' different incarnations of Dexter and Mandark at the end of [[TheMovie ''Ego Trip'']]: the main timeline ones, the wimpy employee Dexter vs. his EvilOverlord boss Mandark, the [[CrowningMomentOfFunny old man]] BigGood Dexter vs. [[CrowningMomentOfFunny Mandark's disembodied brain]] and the ActionHero future Dexter vs. the overweight BigBad Mandark.
* Pretty much the entirety of "Yonni The Yanitor", but this exchange near the end is a noteworthy one; just as Yonni thinks he has won, Dexter turns it on his head:
-->'''Yonni:''' So, Mr. Smarty Pants, what do you have to say now?\\
'''Dexter:''' [[HoistByHisOwnPetard Clean up this mess!]]
