|First Appearance||Meltdown Syndrome|
Leadsuit is Duke Nukem's weak and bumbling sidekick. In Meltdown Syndrome, he reveals that he works for Duke Nukem because when Nukem takes over the world, he'll get to be second in command. Like the other eco-villain sidekicks, Leadsuit tends to take plenty of verbal and physical abuse from his boss; Nukem commonly calls him "Leadhead" and threatens to harm him. He always wears a radiation suit around Nukem, despite other humans being able to come near him without such suits.
In Isle of Solar Energy, Leadsuit can be seen without his suit for the first time, when he is posing as Dr. Apollo's assistant. He has grey hair, a weak frail body and glasses. In The Energy Vampire, Leadsuit gets out of his suit again (albeit awkwardly) and gives himself a back-hump injury. He has brown hair this time.
In Meltdown Syndrome, he was shoved into a dark broom closet by the Planeteers (he didn't even put up a fight or resist). He then said he was scared of the dark, to which Wheeler replied that he'd be more scared of his boss if he were smart.
He is voiced by Frank Welker.
