Kevin Johnson is a physical giant. He is strong and physically fit, making him no one to be trifled with. It is said that he can withstand the impact of a concrete block without injury or pain.

Kevin is quiet, and there are rumors that he seems to be plotting something in his head. Many League members are weary of him and suspicious of his quick advancement to DAD's personal bodyguard.

Kevin Johnson was born and raised in Kansas City Missouri. He knew from an early age that he wanted to protect people. Upon graduating from high school, he immediately join the police academy. He graduated in 1992 with a double major in Criminal Justice and Law Enforcement. He quickly joined the ranks of Kansas City's finest.

In 1993, Kevin was involved in an investigation into a major crime ring in the city, which involved attacks upon one of RAD Technologies' remote labs. This is where Kevin first met DAD, who was following a rumor that his wife (Jessika Kieger) was at the lab site. Kevin's work in the police force became an intrical part in DAD's search for his lost wife. This work provided the foundation for a friendship and loyalty would last for years to come.

However, the results of the "Radtech" investigation ended badly for the Kansas City Police force. Kevin left the police force and joined the League of Unusual Guys. Kevin's past experience in the police force has served the League well. Since Kevin's induction into the LUG, the league has seen an increase in its success rate.

In LUG, Kevin started out as a field agent, and quickly became DAD's personal bodyguard. Despite several members' suspicions of Kevin, DAD seems to trust him without question. Fellow members have speculated that more went on in the criminal ring investigation and the months following than the official report showed.

When Kevin became DAD's personal bodyguard, he chose to undergo a unique procedure. This procedure increased Kevin's strength and endurance. Officially, little is known about what the procedure is, where it was done, or what other effects there are. It is rumored that Kevin has to go through additional "treatment" on a regular basis to maintain his condition.
