Zavaar

Emily: Oh....thanks.....
Emily blushes as she hurries onto her feet. Her rapier glows a deep blue as some of the water from the river suddenly flies out and surrounds the blade, she slashes it to send a high pressure jet of water at the creature.

(the monster roars, ignoring the water from Emily's blade, and out of its mouth flies three more flying frog monsters, which go straight for Mona)
Ziva: Woah, watch out! *sits cross-legged on the ground* This'll be fun! :3

Emily: What the hell? That was supposed to cut into it!
She collects more water to do the same thing as before, this time actually creating a large gash into it.

Mona cleaves into one of the frogs, its guts squirting all over the place as she slowly slices through it.

(the gash heals quite quickly, and the monster angrily clambers toward Emily)
Ziva: Uh, maybe it's just used to water. It IS a water-based monster. Maybe something like lightning would work better?
Olla: Then USE some! *bashes a frog monster, then grabs onto its mouth, holding it shut, and runs her sword into it*
Ziva: *yawn* Nah, I'm kinda tired.

<.<
It's supposed to be just like when Aang and Katara cut through metal with waterbending, how'd it possibly heal from that?

Emily: This isn't the time to be tired!!

well, due to the nature of it, any water-based attack would just splash onto him. Think of it as the Flash Fire ability from Pokemon, but for water-types.

Ziva: But-but...FINE! *her hands start to glow blue, and she fires off a huge bolt of electricity right at the monster's forehead, stunning it slightly* Well, that's all I can do!

Mona: Good! *runs up to the monster and starts swinging her sword at it*

>.>
Fine, you make a good point....

Emily slashes at one of the frog monsters.
Emily: Please work faster.

(Olla jumps up onto the the second frog monster, and throws her shield at the third one, knocking it to the ground)
(the River Monster crashes his fist into the ground at Mona, but due to her speed, he just crashes behind her)
Olla: Mona, use his arm to climb up onto him!

Mona: Of course! *starts running up the monster's arm* Here I come big boy!

(the Monster sends two of his tongues whipping at Mona)
Olla: Watch out! *runs over, but gets tackled by the frog monster she tried to knock out* Argh! Someone help!

Mona cuts the tongues as they swing into her path.

Mona: Keep your tongues in your mouth!

(the Monster roars, and sends his other hand around at Mona, and snatches her off his arm)
Ziva: Oh, here! *sends a bolt of special-looking energy into one of the dead flying frog monsters, and reanimates it* Okay now, I want you to go up there and distract your big daddy!
(the frog monster obliges, and flies up to the River Monster, and swipes at its face with his tongue)

Mona: And I wonder why I never thought to invest in other weapons.... *wiggles and squirms in the monster's hand*

(being annoyed by its dead spawn, the Monster loosens its grip on Mona a little, to the point where it's just holding its palm flat)

Mona: Yes. *restarts her chainsword and runs back up to its back*

Olla: Argh! *keeps bashing at the frog monster with her shield, as it knocked away her sword* Stop attacking me, you beast!
(the River Monster roars, and starts diving back into the water)
Ziva: Hey, come back!

Mona: No you don't! *stabs her sword into the monster's back and runs down it*

(the monster turns around and lashes at Mona some more)
Olla: Ziva, come on, we need some magic!
Ziva: FINE! *holds her hands close to her stomach, and generates a shiny blue sphere of magic, then thrusts forward, and it turns into a huge ball of lightning, which she launches at the monster*
(the ball hits the monster, and explodes, sending the monster reeling backward, launching itself out of the water, and landing on the bank.)
Olla: Now's our chance!

Mona: Let's go! *runs over to the monster*

Olla: Right! *thrusts her sword into the frog monster's gullet, then takes it out, and wriggles out from under it, joining up with Mona* This thing should be weaker out of water, so let's make our attacks count!

Emily: I'll just stay out of this..... It's been proven that I'm useless here.... *Hides behind a barrel*

Ziva: Don't worry, Emily, you can always find a use as my meatshield! *hides behind Emily* These huge gazongas could bounce any attack off!

(cue cool action sequence where Olla and Mona take down the huge River Monster)
Olla: *hops off of its head, panting* huff...wow..that was something! I'm so sweaty...

Mona: Yeah....Me too. You think they have a bath house here?
