Rak Wraithraiser (라크 레크레이셔, Rahk Rekraisher; or "Rac Wreckraiser") is a C-rank Regular from the Wraithraiser species. His position is Spear Bearer. He is a direct descendant of the Native One.
Rak is originally a giant-size creature, a classic Lizardman, but after he mocked Ranker Han Sung Yu , the Second Floor Test Director, his body was shrunken intentionally by the Ranker. He eventually found out how to get back to his giant-size. He has [[red eyes] and Black Sclera, with a Head Spikes/Horns.
He wears Red Robe/Armor, a Red Cape, (although he has been seen to change into a T-Shirt) and carries a huge red Spear. He is a large, powerful warrior and a very confident and optimistic individual.
