In All Fall Down, Count Von Deadly goes out this way, when he loses the ability to control his magic powers.
The entire premise of Bing Bang Benny in The Dandy, drawn by the brilliant Ken Reid, was that it was set in The Wild West and the main character loved using explosives.
In a Deadpool one-shot, he wants to hire a filmmaker to shoot a movie on his life (by the way, unusually for Deadpool, this is a pretty serious story, where the fourth wall remains intact). When he attends the premiere, he's utterly disappointed that the story of his life was essentially turned into this trope.
Deadpool:Aww, c'mon! Was it explosion discount week in Hollywood?
In the Hellboy story Wake the Devil, the vampire Count Giurescu and the cavalry horse he's riding explode into skeletal parts when Hellboy hits them with the post that he's been tied to. Naturally, though, that isn't the end of it.
Hellboy: That's interesting. No matter how hard you hit them, horses don't usually explode... vampires either, for that matter.
This is the job description of the Nextwave squad, and they love it.
Elsa Bloodstone:"They explode! My life has taken on new meaning!"
This is exactly the author's description of the comic, too.
Warren Ellis: "It is people getting kicked, and then exploding. It is a pure comic book, and I will fight anyone who says otherwise. And afterwards, they will explode."
Sin City features a grenade-thrower whose grenades emit massive explosions that are strong enough to send cars flying... despite the fact that grenades don't work that way.
Tex Willer and his pards love blowing up stuff, and are so good at it that if it was a college course they could teach it (their words, not ours). Their crowning achievements are using a dynamite stick to open a doornote in their defence, it was an armoured door and they didn't have the time to just search and find the key and using a few dozens to drain a reservoir and annihilate a gold minenote the latter being an accident: they were trying to just drain the reservoir and thus deprive the mine of the water for their mining-purpose water cannons, but the reservoir was so huge that, once the guys blew open a hole, the water pressure enlarged it and made a flood. Thankfully no victims, as the miners heard it coming and ran away..
This is the main power of at least 2 X-Men characters: Remy "Gambit" LeBeau, and Tabitha "Boom-Boom" Smith. Gambit charges objects (usually normal playing cards) with explosive energy, while Boom-Boom creates hand-held balls of similar power. Gambit is actually one of the most devastatingly powerful examples of this trope in fiction, or at least he would be if he didn't have surgery specifically to weaken his powers. One alternate universe Gambit who didn't have that surgery blew up the Earth.
