Kyle Hoover’s twin brother and Dwayne Hoover’s stepbrother. Lyle is a carbon copy of Kyle, and even Dwayne was not able to tell them apart until 1954 when Lyle’s nose was broken in a fight over a woman at the Roller Derby. Now, Lyle is the twin with the broken nose, and he also does most of the talking between the two. Lyle is the one who tells Dwayne about the industrial waste taking over the Sacred Miracle Cave, and he also tells his stepbrother about their efforts to combat the pollution by riddling it with shotgun shells. When Lyle and Kyle open fire on the toxic waste collecting in the cave, they reflect society’s futile tendency to treat only the symptoms of environmental pollution rather than going directly after the cause.
