Satoru Sayama
On June 28, 1988, Morimura made his professional wrestling debut in Stampede Wrestling against Hart's son, Ross, under the name Tiger Mask (not the same as Satoru Sayama), at a show in Kamloops, British Columbia, Canada. After a couple of matches, he evolved into Black Tomcat. In August 1988, Black Tomcat was one of many wrestlers cut from Stampede, and joined the North Western Wrestling Federation and later won the promotion's Junior Heavyweight Championship, his first title, after defeating Steve Gillespie.
