For each pairing, chose who you think would win in a fight.
If you'd like, explain how you chose the victor.
1."Batshit" Bellatrix LeStrange vs. Narcissa "Not a Sissy" Malfoy - Bellatrix is bad ass and batshit crazy! She reminds me of Katinkanavata whatever from Zoolander. Shmeared red lipstick with a penchant for blood. I feel like Narcissa would get fussy if her hair came undone.
2. Remus "Moony" Lupin vs. Fenrir "Will Eat Your Children" Greyback - Although Fenrir will pour some ketchup on you before feasting on you, Moony has got the brains. Let's hope wits ftw.
3. Gilderoy "Blonde Ambition" Lockhart vs
Ludo "The Wasp" Bagman - Gilderoy can't even handle pixies, even if they were freshly picked.
4. Severus "Don't Call Me Snivellus" Snape vs "Seriously" Sirius Black - Can't you picture Sirius running straight towards Severus with his wand in the air and then Severus just standing there... Then at the last moment steps aside and Sirius falls. Then Snape would AK him. (after they made sweet love :P j/k)
5. Neville "Stubefy" Longbottom vs Peter "Pathetically Pitiful" Pettigrew
