[1] Don Kent is one half of The Fabulous Kangaroos alongside partners Al Costello, Bruno Bekkar or Johnny Heffernan.

After graduating, Kent worked at a Veterans Administration Medical Center in his hometown of Battle Creek while being trained by Leapin’ Larry Chene for a professional wrestling career.

In Arizona, Kent worked a storyline that drew full houses at the Phoenix Madison Square Garden against local face (good guy) Tito Montez.

[2] In 1967, Al Costello reformed the tag team The Fabulous Kangaroos with Ray St. Clair who retired after six months with knee problems.

Kent, who was from Michigan, adopted the Ultra-Australian gimmick (but retained his American accent) and a second version of the Fabulous Kangaroos was formed.

[3] Kent won the NWA Mid-America Heavyweight Championship, the main title of the promotion, in October 1974 by defeating Tony Charles.

On November 1, 1975, Kent defeated Mark Lewin to win the Detroit version of the NWA United States Heavyweight Championship.

[3] On October 16, 1976, Kent regained the title in a bloody brawl against Pampero Firpo and held on to it until January 8, 1977, when he lost it to Gino Hernandez.

[3] Kent developed into a long running enemy of the Sheik, who was the most popular man in the promotion, with the two clashing many times in wild and bloody brawls.

[1] In 1977, having recovered from hip surgery, Al Costello teamed up with Kent as The Fabulous Kangaroos for a tour of Puerto Rico with the World Wrestling Council (WWC).

[3] After their tour in Puerto Rico ended, Don Kent returned to singles wrestling and Costello focused more on managing due to his bad hip.

[3] In 1979, Kent wrestled in Puerto Rico as a singles wrestler, winning the WWC Caribbean Heavyweight Championship from Chief War Cloud on January 6, 1979, and holding it for over 6 months until he lost it to Hurricane Castillo on July 21, 1979.

[3] The final storyline involving the Fabulous Kangaroos saw Al Costello bring in J. J. Dillon to act as his short term replacement as he "took care of business".

When Costello returned from his business trip, Dillon refused to give up the Kangaroos' contracts and was backed up by both Kent and Heffernan (in storyline terms).
