Take a superhero, any superhero and kill 'em good. Kill 'em REAL good. The death should be appropriate to the hero’s powers and abilities:
Superman: Since he’s vulnerable to magic and kryptonite, I’d cast a spell on him and make him climb into a kryptonite-lined lead coffin. I’d then take the coffin and launch it into a black hole. Supes ain’t gonna come back.
Batman: Prepared or not (:D), Bruce can’t withstand a Patriot missile in the chest. Don’t wait up, Alfred.
Wonder Woman: As everyone knows, Amazons are rendered helpless when tied with their own lasso. Therefore, the trick is to tie her down and then exploit her much-publicized peanut allergy. Once she is well secured, her body should be slowly and carefully coated with peanut oil. Of course, any unnecessary articles of her clothing should be removed beforehand, in order to maximize the available surface area. No matter how she struggles and strains at her bonds, every available square centimeter of exposed flesh should be massaged with shimmering, glistening oil…
Oh yeah, She-Hulk, Black Canary and Starfire are also allergic to peanuts.
In an issue of What If . . . the Punisher killed Spider-Man by luring him into a building and then blowing it up. That’d work on most heroes, all you need is a good excuse to get them into that building then . . . KABOOOOOOOOOOOOOOOOOOOOOM!!!
Once again, you’re making the mistake that all evil geniuses make.
YOU AREN’T AROUND TO ACTUALLY WITNESS THE DEATH!
Faster than you can say “It’s a trick!” the black hole will spit the coffin into another quadrant, where it will fly close to a yellow sun. The outer lead layer will melt away, the inner Kryptonite layer will burn up and Superman will be re-energized by the yellow sun. He will then make his way back to earth and kick your ass.
My suggestion – turn Lois Lane evil. It’s the dame. There’s always a dame.
There is only one lasso of truth. One. Diana is the sole possessor of said lasso.
You might be thinking(I use the term loosely, spunk boy) of the Golden Age version where she would lose her powers if a man welded her bracelets together. Post-Crisis that is no longer a plot device that can be used.
I doubt you’d be devious or fast enough to get the lasso, thus leaving Wonder Woman free of your roller derby Charlie’s Angels fantasy.
I can’t possibly compete with no one expects the Spanish Inquisition, but I’ll try.
Sneak up behind Green Lantern with a can of yellow spray paint in each hand, coat him with it (I know, I know, not yellow anymore–I haven’t read a comic in 30 years…so sue me). Then gag and tie him behind a paper target. Hand a quiver full of yellow-tipped arrows to Green Arrow and say “Can you hit that, dude?”
When he finds out what he’s done, Green Arrow will give up archery, and that’s as good as dead.
If you want to mix some peanut oil in there somewhere, feel free.
Spiderman: Mix Ortho “Roach, Ant, Spider spray” with some Raid “Home and Garden Multi Bug Spray,” add in some peanut oil just in case, then put it all into a Ace Home and Garden Sprayer. Disguise the sprayer as a camera and say “Hey Spidey, I’m just a cub reporter trying to make a name for myself. Could you pose for a picture?” That should do it.
Silver Surfer: Using some silver spray paint, coat a ULI Inflatable Surfboard. When it’s dry, show it to him. He’ll be so depressed he’ll just waste away.
