Baku

Baku is the titular character of the Baku series. He stars in every episode and is always seen wearing a grey rain jacket with a green hoodie and an Aku Aku mask from the Crash Bandicoot video game series.

Personality
Baku is a very no-nonsense dude who can't stand other people's blathering. However he often complicates things for himself. Due to his lack of knowledge, unique taste, his unwillingness to let up, and his short temper. Leading to confusing and frustrating arguments for him and for whoever he's arguing with.

Baku also likes to flex his BREAD by frequently buying new iPhones and Y E E Z Y S. Although some of his dough may have come from him not paying the bills or tax fraud.

"Yung Cash Register" AKA "Lil' Broomstick"
When Baku first meets "Yung Cash Register" AKA "Lil' Broomstick" in S2:E3 he was annoyed by "Yung Cash Register" AKA "Lil' Broomstick's" time wasting rap shit. And argues with him over the phone. Despite Baku's clear frustration and unfriendliness toward "Yung Cash Register" AKA "Lil' Broomstick", "Yung Cash Register" AKA "Lil' Broomstick" still treated him like a friend.

Over the course of the anime "Yung Cash Register" AKA "Lil' Broomstick" started to coincidentally appear more often around Baku. As this happens Baku starts to grow less annoyed by "Yung Cash Register" AKA "Lil' Broomstick's" presence and starts treating him more like a friend. And eventually even goes with "Yung Cash Register" AKA "Lil' Broomstick's" to Egg Foo Young without egg in S4:E7.

YEET
Sometimes when Baku has had enough of other people's MF dumbass shit. He will YEET at his foes. Which sends them into the 3rd dimension. As explained by Obito in S5:E2 the characters of the baku anime all live in a 2d dimension. And when baku uses YEET he pushes people backwards into the 3rd dimension. Effectively trapping them in a void they cannot escape. Unless they can teleport themselves back into the 2nd dimension like Obito and Swagkage.

Kanye West
Kanye West is shown so far to be baku's last resort. With this move he summons his persona: Kanye West to attack his enemies. So far, Kanye West was able fuck up at least two robot armored police-men, both with a single attack.

Behind the scenes
In the video "how i make these shits," Sethical, the creator of the anime, states that Baku doesn't actually have any hands.
