A game of cat and supermouse (private)
 

(Aleight I think I'll start.)

Catwoman was in the middle of robbing the metropolis museum of a very large green gem.

(it's kryptonite)

Catwoman only found the reason to rob the museum's kryptonite for like most of her criminal record would is that its a statue of a cat that and any enemy of Superman would pay big bucks on the blackmarket for the kryptonite mineral even if its small. About the only thing Catwoman at the moment finds strange is the lack of security around the place as her work in a museum thief she has been in this town has one of the lowest security set up as shes taking her time she spys her pray a ancient kryptonite statue of a persian cat in the Egypt exhibit

(wait i forgot. who's playing who?)

but unbeknownst to her, supergirl was flying near the museum while on patrol. and she soon notices some strang behavior.

(For me it was Catwoman you got supergirl but we could change if you want)

Catwoman figured once she replaced the statue with a fake remake made to match then without a waste bolted for the exit safely unknown to her even with her extremely unnaturally good hearing and eyesight that all her precautions to keep from being caught was put to risk with being seen by the super hero sidekick/adopted cousin of Superman is near namely Supergirl who has a limited protection against kryptonite.

(no i'm fine with it)

Supergirl noticed soemthing with her superhearing and decided to use her x-ray vision to see what was going on inside the museum. she saw catwoman in there so she rushed in there.

With a sense of smell about as strong as a cats Catwoman picks up the sent of someone coming in with what seems to Catwomans experience flying speed and not of Superman she knows his smell this smell is similer though about like there of the same race or close to it so without wasting time she bolts the opposite direction being carefull not to trigger any alarms but she does trigger one when she came close to dropping her prize

Supergirl soon arrived in the place and spotted her. there you are! she quickly flew straight at her.

Catwoman smirked using her head as she held the kryptonite statue infront of her knowing Supergirl isn't immune but strong against kryptonite compared to superman in weakness field.''look girly do you really want to never go to a muesen in your home town because of this, For you'll be found out!? Besides that I won't let anyone have it''Catwoman is trying to get away with it by trying to get Supergirl tempted enough to let her walk away with the kryptonite

(Sorry I never noted the gem aspect in your first post till now because I was pissed at the server so lets just keep going that its a statue as Catwoman in the batman cartoon was always after cat like items )

(fine, fine fine. Do what you will)

Supergirl suddenly started to waken. Ohh.. She fell to her knee's. I feel so weak..

(it was sort of hard to understand that, so I just went with something)

(Okay sorry not the best at phrasing things)

''lets make a deal I return the statue if you win aliitle game kitten''Catwoman said as she walks backwards towards the exit door
