Brawlhalla is a game played by the Deprimus members.
The game suffers from signature spam mechanics. It became a meme because everyone can spam sig moves with 0 skill and win. This is why the game is so annoying.
Orion is a legend that has signature moves which can be very easily spammed. Therefore, it's very popular among low-skilled players. Sometimes, premade players both play Orion. This is a combo that's annoying to play against.
Teros is a legend that looks like a bull, and has a lot of attack points. There was a world champion that mained Teros, but has retired. Teros is seen as a very annoying character because he can hit you like 4 times and you're done. His most annoying move is Nsig, which makes him swing his axe up and down, launching enemies 100km away.
Lord Vraxx is a legend in the game. Playing with him requires 0 skill due to his dexterity. UW always laughs when he takes his opponents into the lance and throws them out of the map.
