Your Avatar Is Your Magical Girl Outfit.

[Something-kun]

ninja

[Chiru Masquerade]

This will work perfectly 3nodding

[Infinitian]

Pretty alright on the practicality scale, not too bad; I think it looks stylish but that's a personal opinion; I think it would be cool if I could control skeletons, perhaps? Not, like, zombies, just straight up skeletons

[Its Contagious]

Smack people with my giant whatever this is.
I'm snazzy as hell though.

[husky haya]

...I don't have any weapons. ;_;
I impale witches with my horns?

[Sora Kitty]

Very pink, but it would actually work out pretty good! xd
I'm guessing I'd be able to fly, and cast some sort of magical girl spells. Maybe something flower related, given the hat.

[Miss Mizuno]

Oh haha my outfit is perfect, I'm very pink and rosy and cute whee

I think my powers are powers of nature and romance, kind of like a mixture of Sailor Jupiter and Sailor Venus, I suppose.
I can summon a rose staff that does magic and I have lovely gymnastic skills.

[Silvia Crow]

So apparently I turn into an undead centaur necromancer/horseman of death when I get all "magical girl'ed".

I'm ok with this.

*Summons legions of the dead to fight the witches*

[Joslyn Alia Nine]

I can't fight in flip-flops stare

[Mayor Gravity]

Alright then.

[Chance Time]

Let's see, I would be agile and quick, but I wouldn't be able to fight, seeing as I don't have a weapon! razz

[Winged Timberwolf]

Aw yeah, robot girl. :B

[Cheralla Sakura]

Fighting witches with the ultimate weapon: pie.

I have a feeling my powers would tend to revolve around pranks and things.

[Chaos_Bunny]

Oh yeah, ninja witch hunter!

[lunefall]

........ I whack people with lollipops. Okay.
My powers are sweets related. xD
I think this is still kinda practical? xD
