Who would be your segundo in a Wizard Duel?

Severus Snape, no doubt about it!

Dumbledore, I don't think anyone would want to beat me if they had to fight Dumbledore afterwords.

Hermione. :D

Mine would have to be Harry, the Boy who defeated the Dark Lord.

Bellatrix

My fiance Joe. Of course, and he would be perfect 4 the job.

Siruis black or N.tonks

I think Hermione or Sirius!

Severus Snape.

Dumbledore! Definitely. Nobody's quite as great as he is.

Yeah, I'd go with Severus too. Hopefully his presence there would unnerve my opponent (specially if they'd been his student previously)

If I've to pick, I would pick Luna Lovegood. segundo of your duel is the one who takes your place when you are in no condition of duelling. She is a good dueller. But madami than that, a segundo should be good in healing. Then Luna is an obvious choice. She's very good at healing (using "Episkey" and all). So,, LUNA...

Sirius

Regulus Arcturus Black =)

I'm a girl. An antifeminist one. I can't picture myself dueling. I'd prefer others to duel for me. That was a joke. Others dueling for me, I mean, not me being a girl or an antifeminist. That's not a joke, you can see it on my profile. That I'm a girl. Not that I'm an antifeminist. You can't see that, but that's not a joke either. Dead serious stuff.
So be it, I'm dueling someone. My segundo would be Albus Dumbledore. If I'm to die in a wizarding duel, into which I'd never get in the first place, it's the least that someone sends my opponent after me. You know. To finish the duel, to have a snack. Philadelphia Cheese Cream. Dumbledore kicked lots of ass. He'd make sure I get my opponent got his cheese. I'd gratefully thank him. Is there such as Philadelphia prambuwesas Jam?

Severus, of course ! If he is with me, it means he's not against me. He's formidable an adversary.

Sirius Black

Either Harry Potter or Dumbledore. Maybe Sirius Black.

Hermoine shes amazing wit spells ad knos her way out

Eather Bellatrix or Hermione...
Totaly different ends of the spectrum here I know!

Umbridge. Then if I die, I have the consolation that she'll probably die to.

Voldemort. No doubt. Greatest dark wizard of all time, who, in Dumbledore's words, knows madami about magic than any other wizard (of the 20th century)? Being that tripped out on the Dark Arts must make you damn good at offensive magic. Whoever was duelling me would no doubt die, probably painfully. Unless they were Harry Potter, but that's because he's Harry Potter and not because of superior duelling talent.
