One-Arm

Luke Skywalker's wampa was a wampa who attacked Luke Skywalker during his visits on Hoth. On his first visit, shortly before the Battle of Hoth, he was attacked by it while scouting the area. It knocked him unconsience and his tauntaun and brought them back to its lair. When Luke woke up, he was dangling from the ceiling. The wampa was eating his mount. When the creature noticed him, Luke was able to use the Force to get hold of his lightsaber and escape. Luke escaped with scars and bruses, while the wampa had lost its arm.

Many years later, in 12 ABY, when Skywalker came back to Hoth with Callista Ming, the same wampa recognized Luke and attacked. The wampa was slain by Luke in the battle.
