He would be solely a singles wrestler, until 1989, when he started getting in tag team matches with Wanz, Dave Taylor, and Steve Wright, among others, as his partners.
While in NJPW, he wrestled with the likes of Hiroshi Hase, Osamu Kido, Shinya Hashimoto, and Keiji Mutoh.
In 1996, Schumann returned to NJPW, to participate in the Best of the Super Juniors tournament, which was won by Black Tiger II.
In February 1998, he wrestled in the United States, to challenge Dan Severn for the NWA World Heavyweight Championship.
As CWA shut down in December 1999, Schumann was free to run his NWA territory full-time in Germany and Austria.
He wrestled his retirement match on October 18, 2002, teaming with Günther Wagner, defeating Aykut Artan and Barish Günay.
In June 2011, Schumann made a one-night return to the ring against fellow former CWA alumnus Karsten Kretschmer, in which he lost via disqualification.
