- Actor Allusion:
- While all of the characters call the Red Hulk "Red", Eliza Dushku using that as a nickname should sound familiar.
- In the Lotus-Eater Machine in "It's A Wonderful Smash", A-Bomb mentions that he's actually dating Eliza Dushku.
- Hercules' Boisterous Bruiser personality may bring another superhero played by Townsend Coleman to mind.
- Clancy Brown voices Red Hulk, a red skinned character with a military background, and is a jerk with a heart of gold? Why is that familiar ?
- Hey, It's That Sound!: Annihilus's Cosmic Control Rod makes the same sounds as a lightsaber, the most notable one being its activation sound. The same episode also has the fighters' laser cannons borrowing the same firing sound as the Imperial Walkers.
