- Eldritch Abomination: The monster definitely counts, being a huge pink blob with multiple eyes and tentacles and a red-lipped mouth full of fangs.
- Stable Time Loop: The episode ends with the implication that Dee-Dee may not be able to warn Dexter against opening the portal even if she did go back in time to do it.
Magmanamus contains examples of:
- Anti-Villain: Magmanamus doesn't want to hurt anyone. All he wants is to get some sleep.
- Berserk Button: Don't disturb Magamanamus' sleep.

Marternal Combat contains examples of:
- Men Can't Keep House: It's proven in this episode that Dexter is incapable of taking care of the house.
- Mundane Object Amazement: "Could this strange phenomenon be the substance Mom calls dust?"
- Pun-Based Title: The title is a pun on Mortal Kombat

- Shout-Out: There is one to Rock Sock Em Robots during the fight between the two robots when one of the robots uppercuts the other and makes it's neck extend. Dee Dee does the same to Dexter at the end of the episode.
