Daylyt and Dizaster had a one-round battle during the Road to Total Slaughter event.

Megaton saying "MEGATON, BITCH!!!" as his intro is meant to mirror Dizaster saying "I'M IN [X city here]!!!" in all his intros.

Megaton says Big Zee is "nothing but a fake character". Daylyt was still known for being a troll and a character when this movie was made.

Megaton punching Zee is an obvious nod to Dizaster punching Math Hoffa during their battle.

Daylyt's character being the one to get punched is a reference to the fact that Daylyt and Dizaster (supposedly) got into a fistfight after the incident with Math Hoffa.

Daylyt's character being at an event that shut down over a fight is a reference to one of Hoffa's own incidents where he punched out Serius Jones, shutting down an event that Daylyt was supposed to battle at. The biggest difference is that Daylyt was the one to get punched out instead of being a mere witness.
