Harry Potter prep gauntlet

Harry Potter gets 2 weeks of prep; his opponents get zero. How far does he go? Typical weaponry. Potter has prior knowledge, but his opponents do not.

A) Average Predator

B) T-1000

C) Batman

D) Master Chief

D) Spider-Man

E) Darth Vader

F) Colossus

G) Agent Smith

H) Aquaman

I) Hancock

J) Enterprise-D with full shields, weaponry

With prep he can get the invisibility cloak and just Avada Kedavra anyone while hiding. What about morals?

@rbt: The question remains whether Avada Kedavra would work on those in the list. Everyone is in character, including Harry Potter, but victory is most certainly desired.

This. Assuming Harry is morals off.

Although the Avada Kedavra spell wouldn't work on the T-1000 and probably not on Agent Smith either.

@johnnyz256: It'll work on everybody living. Except T1000 and Smith.

There are other ways of defeating T1000. Not sure about Smith.

I dont see him winning much to be honest morals on and a cloak does not equal win.
