Inu-chan!
I think inuyasha would make for a good crossover rp. It would be simple to make, and there are many way's that the shows would fit together.
The shikkon shards could start showing up (For non inuyasha fans, these are fragments of a chrystal that can make the darkest wish of any creature come true. In ancient Japan, a girl from a deamon exterminating village gets in a huge fight with some deamons, and at the end of the fight, she is loosing, and her soul shoots out of her body in the form of the shikkon no tamma. The Shikkon no tamma is given to a priestess who is able to protect it. A half deamon half human named inu-yasha tries to steal it, and some how falls in love with the priestess, Kikyo. Kikyo is also at the time taking care of a bandit who has burns all over his body, named onigumo*spelling?* He falls for her too, and lets deamons kill him, stealing there bodys and becoming a deamon himself. He shapeshifts into Kikyo, attacking inuyasha. Inuyasha is to angry to figure out what had happened, and goes into the village to steal the Shikkon no Tamma. He was going to use it to turn human and live his life with Kikyo, but now he wanted to be full deamon. Kikyo is then attacked by a fake inuyasha, and then goes off to kill inuyasha. She attacks Inuyasha while he is leaving the village, pinning him to a tree with a cursed arrow. She dies, and Inuyasha remains trapped with the spell of the arrow for 50 years. Kikyo reincarnates into a 15 year old girl named Kagome. While looking for her brother's pet cat, Kagome is attacked by a centapeed deamon in a well at the back of her home. She wakes up in Ancient Japan, ends up freeing inuyasha, and finds out that the shikkon no tamma is sealed within her body. It comes out when fighting the centepeed deamon, and later the jewel ends up braking into many diferent chards. Kagome has to work with inuyasha to find the shards, and he is bound to her by a spell in a cursed necklace. Now, Kagome can controle him with the word "SIT!". Anyways, if an evil creature gets a hold of a shard, it gets a WHOLE LOT STRONGER. They also have to deal with Nuraku, the deamon that was once Onigumo.*Spelling?* Anyways, long story, but I think it would work for a crosseover.)
For those of you who watch Inuyasha, think of these points.
What would happen if some realy evily badguys off of buffy ended up with Shikkon shards?
What would happen if Youkai started showing up as well.
And how would Kagome feel if she had to go to America?
Hm, Inuyasha,, how would he react?
And last, but not least, think of all the wonderfull made-up charactes that could end up involved.
*big, sparkly eyes.* 0-0 'yeah!'
