He didn't save them from destruction, though, or I'd have given it to you. It's sorta the point of his action, the Guardians' rules wouldn't let him just build nice new homes for everybody.

That makes sense. Well, I assume you meant me as "closest", so here goes.

Maybe this will ring a bell: what do the Riddler, Plastic Man, and Lex Luthor have in common?

Looking for something specific here.

They're all really smart...

I don't know if Iggy meant you, I was the one who said Stewart did a rebuild. I'm waiting for Iggy to say who he meant got the thread.

I meant cucr

OK then.

As for the answer, it's quite obvious. Since they all have one particular thing in common. They're all comicbook characters in the DC universe.
Since CuCr didn't ask for anything exact, that answer works.
And all three previously appeared in comics by other companies before they began mergthe universes to form the DC universe.
Oh, and all three have been on both sides of the law, so they all have criminal records.

And none of them have ever been in your kitchen, either.

I did say that I was looking for something specific (and there's a clue to it in my wording of the original question).

All three had been the bell of the ball in their respective times ?

All three tried out for roles on "Saved By The Bell", tho only to get close to Elizabeth Berkley ?

All three have been firemen?

All three, during their respective times in high school, use to pull the fire alarm bell to get out of class early?

All three have used the Liberty Bell in a caper of some sort or another?

Step up to the mike and make another guess....

They've all had cancer..?

I'm starting to feel like Edmund Blackadder. "You lot wouldn't recognize a subtle clue if it painted itself purple and danced naked on top of a harpsichord singing 'Subtle clues are here again'!"

All have had a public change of heart - Riddler went from supervillain to crime-solving detective; Plas went from petty crook to shape-changing sleuth; Lex went from supervillain to US President.

*sigh* This was a really bad idea for a trivia question. The answer I was looking for was that all three characters have been portrayed by voice actor Michael Bell: The Riddler on Challenge of the Superfriends, Plastic Man on his own Saturday-morning show, and Lex Luthor in the late-1980s Superman cartoon.

For no really good reason I'll let Wyld have it.
