"Hunger Pains" is a comic featured within Star Wars Tales 20 that tells the story of One-Arm and his offspring. In a departure from accepted Star Wars Legends continuity, One-Arm is depicted as a male character.
Set in 3 ABY, preceding the renowned Battle of Hoth, the narrative begins with a wampa's offspring expressing their starvation. He then clarifies that the arrival of humans has caused a scarcity of Tauntauns, the wampas' favored prey, owing to their domestication. Driven by the need to feed his young, the wampa embarks on a futile quest for Tauntauns, only to encounter Luke Skywalker, riding one.
Driven by intense hunger, the wampa devours the Tauntaun entirely after suspending Skywalker upside down. He then resolves to offer Skywalker to his children. However, Skywalker employs his lightsaber to sever the wampa's right arm and flee, thus cementing the wampa's identity as One-Arm. Ultimately, he presents his severed limb to his offspring, withholding the information that it isn't Tauntaun meat and that it is actually his own arm.
