Characters who'll always — or never — get into a fight when they meet

This is going to yet again demonstrate my dorkiness, but I immediately thought:

---

Wesley Crusher and Xander Harris****

would hate each other, and their meeting would rapidly devolve into a slapfest.

Sort-of happened, in the 90s.

Brave & Bold Annual.

Co-stared Ralph Dibny & a Sam Spade-type detective.

Unless this happened multiple times, I believe you are thinking of Detective Comics, to celebrate some big milestone (big round number anniversary or issue #) of that title, with a plot celebrating when there were more detectives than just Batman in D.C… Late '80s or early '90s.

Did you mean Sauron, or Saruman? Saruman seems a better rival for Elminster. For Sauron, I think you’d have to kick it up a notch to Fizban.

I meant the evil wizard dude that sent the Ring Wraiths after Frodo & Friends. I say Elminster takes him.

Correct.
2nd Robin also appeared.
Moriarty descendant was the villain.

Holmes had been/still is living in a monastery in Tibet, lifespan extended by a distillation of royal bee jelly.
