Kill Dr. Doom

The following characters are sent to kill Dr. Doom in his castle at Latveria under varying circumstances. They all get a month of prep and can bring whatever gear they have used before.
Bullseye
Punisher
Taskmaster
Wolverine
Sabretooth
Omega Red

Scenario 1- Doom doesnt know anyone is coming, each works alone.
Scenario 2- They work as a team, again Doom doesnt know they are coming.
Scenario 3- They work as a team, Doom has 1 day of prep but cant leave.

For scenario 1, does anyone score a kill, or who comes closest.

Wolverine's used a teleportation device before.

He teleports behind Doom and decapitates him right after Doom gets back from banging Morgan Le Fay.

Doom destroys all of them...

However, since that's not an answer...

Bullseye
Taskmaster
Wolverine
Sabertooth
And Omega Red can all do it.
