Werewolf

The Werewolf is a Hardmode enemy that spawns only during a full moon, during which they are as common as Zombies. Werewolves can open doors, and can inflict the Bleeding debuff.

At close range, Werewolves attack the player by leaping or lunging at them, closing distances quickly to catch unwary players off-guard.

The player can transform into a Werewolf by wearing the Moon Charm at night, which has a 1 in 60 chance of dropping.

Trivia

 * In common lore, the main weakness of werewolves is silver (i.e. silver bullets), but silver items in Terraria offer no particular benefit in dealing with them. Ironically, they also drop silver coins.
