Wait, what? The Undertaker? In New Japan Pro Wrestling? What the bloody hell am I talking about, right? Well, ladies and gentlemen, this is very much true.

Just before signing with the WWE, Taker had a short run with WCW - under the name of "Punisher" Dice Morgan - as a part of their collaboration agreement with NJPW. He was in the Land of the Rising Sun for three short weeks where he wrestled a few matches before returning stateside to sign with the WWE and embark on his journey to immortality.
