Stealth Moose
Umbrella Elite
This reminds me of a What If comic featuring the Punisher killing Spider-Man. The plan was surprisingly simple: Punisher made a decoy which looked like Doc Ock that was rigged with an explosive. Spidey goes to investigate, attempts to engage his mortal foe, boom. End of Spidey. Spider sense thinks Ock is a danger because he is, but how he is dangerous is not immediately known.
Doing this to a Jedi would be a bit tricker. For example, put explosives on Mission and send her sprinting at a no-name Jedi.
Another good method is a chemical weapon. There's one which isn't inhaled but goes through your pores and messes you up. That'll do the trick.
