Willy

""What took you d****bags so long?""

- ~ Willy to Angelino (film)

Willy is one of the two tritagonists (along with Luna) in Mutafukaz, being a somewhat irritating but long-standing friend of Angelino and Vinz. Despite often complaining about his selfish and unlikable behaviour, the duo tolerates him, likely because the three have known each other since childhood.

Willy is also shown to have connections within the Russian mafia, although the nature of his relationship with them is not entirely clear.

Personality
Willy is a highly selfish, dishonest and cowardly person. His interactions with Angelino and Vinz show that he's not above lying to his close friends and manipulating them for his own gain. Whenever he feels threatened, Willy opts to immediately run away, hide or surrender, even when this puts Angelino and Vinz's lives in danger.

He is also repeatedly shown to be loud, whiny and very insensitive. He displays no concern when visitingAngelino and Vinz's apartment, agitating Lino's headache with his shouting. Later, when Angelino opens up about being abandoned by his mother, Willy can't resist cracking a joke at his expense.

Trivia

 * Willy's surname is a reference to pipistrelle bats. The name of the genus is itself derived from the Italian word for "bat", pipistrello.
 * Willy was initially called "Kurkoï". RUN changed the name in 1999, basing it on a paranoid colleague who spoke to him about his conspiracy theories.
