#1 Kamala's character being strong enough to build stars
As mentioned, Kamala's character was among one of the most intimidating in pro wrestling history. Billed as The Ugandan Giant, Kamala spent a good portion in the WWE being managed by Kim Chee, who acted as more of a handler. This element alone made Kamala look even more intimidating, which helped his role of making babyfaces look good.
Other than Hulk Hogan and The Undertaker, Kamala also helped propel names such as The Ultimate Warrior, Bam Bam Bigelow, and Shawn Michaels. Although WWE did not use him very strongly following his feud with The Undertaker, he already did a great job of helping build stars, while also looking like a big name himself.
Kamala had a short WCW stint that did not help him overall, but Lawler once again showed his dedication to him by feuding and teaming with him once again in 2002 and 2003 in various promotions, including Memphis Wrestling.
In 2001, Kamala made a WWE return after eight years to compete in the WrestleMania 17 Gimmick Battle Royal. In 2005, WWE made an in-ring appearance on SmackDown in a no-contest match against Randy Orton. In 2006, Umaga handily defeated Kamala on the June 26 episode of Raw. These were the final in-ring appearance of Kamala for WWE.
