Profile:
Rintrah, the Revenger from R'Vaal, was a magical apprentice to the alien magus Enitharmon the Weaver in another dimension.  After Dr. Strange enlisted the aid of Enitharmon to repair his tattered Cloak of Levitation, Rintrah delivered the renewed Cloak to Strange on Earth.  Rintrah's often-uttered exclamation was: "By the Warp and Woof of the Woven Worlds!"

After sharing some adventures with the good Doctor, Rintrah returned to his home dimension with Enitharmon (in Strange Tales vol. 2, #17 (Aug. 1988)).   Rintrah soon returned to Earth (in Doctor Strange Sorcerer Supreme #5 (July. 1989)), stating that Enitharmon had taught him all he can... or cared to.  Rintrah then became an apprentice of Dr. Strange, and after some challenging times earned both the respect of his new Master as well as Strange's original blue Cloak of Levitation and Amulet of Agamotto.

Rintrah often masked his brutish appearance by donning the visage of old movie stars (like Bogart).  He was known for his humor, loyalty, and directness, and ultimately those qualities resulted in his abrupt (but hopefully not final) demise.
