The avatar above is fighting you, do you survive?

[One-Eye the wildcat]

A, you have no avatar
B, your form/size/strength is unclear and unspecified.
C, although you have no avatar, you somehow manage to defeat a wildcat, one of the largest and most powerful species in the Redwall universe.
D, what the bloody hell is a 'taiwha'?

[shisteer of nothing much]

None of those are against the rules. The only rule is that you can't choose the avatar, it has to be the one above you.
Besides, I never said I defeated you. You were the one to admit defeat.
I have no idea what a 'taiwha' is but a the word 'Taniwha' means monster in Maori. In legend, they're generally described as large, water dwelling, reptiles but that isn't necessarily a given.
Since you said I could defeat you; *burns One-Eye to a crisp with fire breath* I survive.

[Sebias of Redwall]

*Wins* 

[The Skarzs]

Perhaps.

[Sebias of Redwall]

Hmm... I'd need a pick...

[shisteer of nothing much]

I win, no question about it.

[Jarky Thistlebrush]

*Squashes the invisible nothingness*

[shisteer of nothing much]

*wriggles out from under Jarky and then separates her from her head* I win.

[The Grey Coincidence]

Can I beat Jarky? Yes.

[One-Eye the wildcat]

too easy!

[shisteer of nothing much]

Can I best One-Eye? Hmmm... Yep. *burns One-Eye's head off* I win.

[One-Eye the wildcat]

You don't have fire, you don't even have a body XD. I can't kill you, but you can't kill me either.

[shisteer of nothing much]

I have fire and a body, you just aren't using your imagination. (possibly because I burnt it)

[One-Eye the wildcat]

*Reforms and cuts up Teer*

[shisteer of nothing much]

*raises eyebrow as One-Eye uselessly hacks at foot with a small knife* And how do you plan to do that? I'm a gianormous Taniwha, for goodness sake. Even if you had something sharp enough to get through my scales, I would destroy you before you had time to use it. *lifts up foot and stomps on One-Eye* I win.
