Baldi

Baldi is the main antagonist of Baldi's Basics in Education and Learning, and by extension, the videos Calamituff makes about Baldi's Basics. In Calamituff lore, he is a crack abusing god.

BALDI'S FUCKING SATURDAY EVENING
Baldi chases Laura around his crack shack in an attempt to capture her, with help from his cohorts. He plays many tricks, and almost gets her, but Waluigi saves her before it's too late, reducing Baldi to ash. He survives and recovers.

Crunkid's Summer Vacation
The volcano's eruption summons Baldi and empowers him, allowing him to cause devastation to the island. He murders Death and War, then summons The Raccoon to his side. Waluigi appears again to stop Baldi, and after being spanked by Happy Frog, Baldi is thrown into the volcano and defeated again.

Infiltration
While not appearing in person, at the end of Infiltration, ??? is heard singing Happy Birthday to Baldi, reviving him again.

BALDI'S BASTARDISED BIRTHDAY BALLISTICS
Baldi finds Laura and trips acid, going after her again. Laura runs into the old crack shack, and relives the first Baldi video. Eventually Laura reaches the final exit, but is stopped by all of Baldi's friends and given a giant cake. After she blows out the candles, she finds a device that teleports her to Baldi. Baldi then catches Laura, leaving her fate unknown.
