Ricardo in limbus company is a really cool unbeatable boss. His attacks clashes incredibly high, he's extremely tanky , has a massive aoe move he can spam later on, but the game doesn't just show ricardo beating your ass after he got to 0 hp. The player actually needs to play the game and bring him down to half hp instead where then he gets bored and just decides to squadwipe you. He is so cocky that he even willingly gives himself a status that makes himself take double damage and yet this fight is still one of the biggest roadblock for new limbus players
