* ActorAllusion:
--> '''Iron Man to War Machine''': Stop talking like [[Creator/LeVarBurton you're]] on Reading Rainbow!
* CastingGag: Creator/AdamWest as the Franchise/{{Batman}} {{expy}} Nighthawk, Creator/SusanEisenberg [[WesternAnimation/JusticeLeague as the]] Franchise/WonderWoman expy Power Princess, and [[TheVampireDiaries Nina Dobrev]] as ComicBook/WerewolfByNight's girlfriend, [[spoiler:who gets turned into a vampire]].
** [[Series/HerculesTheLegendaryJourneys Kevin Sorbo]] as Ka-Zar.
* ChannelHop: Reruns went from Creator/CartoonNetwork to Creator/TheHub due to Hasbro's involvement with the Super Hero Squad toyline (though Cartoon Network was also getting rid of Marvel-related content anyway, [[Creator/{{Disney}} for obvious reasons]]).
* ScrewedByTheNetwork: When Season 2 started on Cartoon Network, it only aired on Saturday mornings at 6:30 AM. Disney's purchase of Marvel was likely a factor in this.
* TalkingToHimself: Lampshaded.
--> '''M.O.D.O.K''': [referring to Iron Man] I tried to tell him, but it's like I'm talking to myself.
* WhatCouldHaveBeen: Franchise/SpiderMan was slated to appear in the series during conception, possibly in Falcon's spot, but Creator/{{Sony}} refused due to their ownership of the TV rights to the character at the time. Even after Sony returned the TV rights to Marvel following Disney's acquisition of said company, he still wasn't able to appear at all in the series. The closest we got was in the ''WesternAnimation/UltimateSpiderMan'' episode "Flight of the Iron Spider", which shows a SHS-Spidey in one of Spidey's own {{Imagine Spot}}s as Tony Stark is talking about an invention that can send people into different dimensions [[spoiler:which also serves as a ChekhovsGun as that's how he gets rid of the Living Laser - sending him exactly into ''SHSS'' to be beaten up by Thor]].
** This is somewhat rectified by him (and some other Spider-Heroes) appearing in [[VideoGame/SuperHeroSquadOnline the online game]], which for all intents and purposes is the same universe as the cartoon.
* WrittenByCastMember: Creator/TomKenny co-wrote "Missing: Impossible!"
