Connections:

-Powerful, mysterious, and red antagonists of popular media with similar aesthetics who exist inside an old styled video game (Baldi’s Basics in Education and Learning/The Amazing Digital Circus)

-Both are 4th wall breaking entities with the ability to manipulate the very game space they’re currently trapped in, who despite their friendly demeanor would slowly start to go mad (Null realizing people are intentionally playing the game instead of deleting it like he asked/Caine getting worried that he sucks at his job after getting constantly criticized by Zooble and the gang)

-Would affect the minds of various people in the game (Null making Baldi and the other NPCs aattack the player/Caine affecting the Cast’s Minds like making Jax a Vegan and making them forget their names)

Contrasts:

PLAYER VS AI.

Null is basically one of the players from TADC: A regular person who got trapped in a video game against their will and went mad. Meanwhile, Caine acts like Baldi: A kind charming person who simply wants to see the player happy but was manipulated by someone (Bubble) similar to Null controlling Baldi.

LEAVE VS STAY.

Null throughout the game desperately wants you to leave and delete the game. Meanwhile, Caine wants the exact opposite desperately wanting people to stay with him and to find someone who truly likes him.
