gandalf runs a gauntlet

Round one harry potter

Round two voldemort

Round three sauramon

Round four doctor strange

Round five Dumbledore

Round six sauron

No prep to surrender or death fights happen in Hogwarts start twenty yards away Gandalf heals after every round

Why is Harry above Dumbledore and Voldemort...

which version of Gandalf?

Return of the king

He probably makes it up to Sauron.

Gandalf beats everyone except for Dr. Strange.

Stops at Dumbledore if he has the elder wand

could lose round 4, if not, stops at round 6

Unfortunately, he's canonically below Sauron.

How so ?

who's sauramon?
