Alatreon is an elder dragon from Capcom's Monster Hunter series, a black dragon known for shifting between fire, ice, dragon and lightning attacks. It became especially well known after its return as a high-difficulty hunt in Monster Hunter World: Iceborne, where its entrance and roar became a memorable part of the fight. Clips of the battle spread through gameplay videos and soundboards, and creators still use the roar today because it instantly signals an elite, endgame-level threat without needing any dialogue or explanation.
