What happens if あなた are a half werewolf-half vampire?

Well,if あなた mean someone born from a 狼, オオカミ and a vampire parent, that probably cant happen unless maybe if the vamp is a hybrid like Renesmee ( Stephanie Myers wont officially reveal if she can have babies.) We do know that female vamps cant have babies, and it is implied that female オオカミ cant either, since Leah stopped having her period after she transitioned. Therefore, there can be no crossbreeding.
If あなた are talking about one species being turned によって another, I have a pretty long answer. In the Twilight universe we really cant answer this because we dont know much about their version of werewolves, since it is revealed in Breaking Dawn that Jacob and his フレンズ are not werewolves, they are shapeshifters. This means that they are born this way, and cant turn anyone else into werewolves, so they cant create vampire,werewolve hybrids. It the Twilight universe vampire venom is poisonous to the shapeshifters, so they would most likely die instead of becoming a vampire, so the ヴァンパイア cant create hybrids using them either.

In one of my Twilight ファン fictions, two of the characters were half-vampire/half-werewolf. My guess is that a half-vamp/half-werewolf would be able to shapeshift into a wolf, but his/her diet would (preferably) consist of blood rather than actual food, even though he/she would be able to eat human 食 if they really wanted to. I also think that they would have the same abilities as any normal vampire, such as running at a super human speed. Their body temperatures would probably be in between freezing cold and very warm, so most likely they'd have an average human body temperature. Their skin would also probably be in between tan and pale, if not one of either extremes. Hope this helps answer your question!
: )

Tat would be difficult. I guess you'd be a hybrid; see tyler lockewood.

ha?that's odd.

ha?that's odd.

THE are both vampire and werewolf and have to live with it whether they like it または not

Well then the baby would be both half vampire and half werewolf and it would be considered a Hybrid. Like Tyler Lockwood from the Vampire Diaries または The guy from teh movie the Underworld:)

I would try to find a cure cause i really dont like being a werewolf but a vampire that would be great!

With Stephenie あなた never know. If Jacob and nessie were to have kids they would not be wolf/vampire. Like Billy it would skip a generation and it would be different. The Volutri will not allow it.

well if nessie can't get pregnant then one way a vamp/wolf crossbreed could happen is for a male vampire and one of the human women from the tribe to get together the baby would have vampire blood and werewolf blood in the 本 that 発言しました the boys started turning into wolfs because the ヴァンパイア was in town so the vamp blood in the baby would couls the 狼, オオカミ blood to react... it's hard to tell if the baby would be もっと見る powerful than the ヴァンパイア and wolfs being a クロス of the two または if the two bloods would just kill the baby "vampire venom kills wolfs"

I would say it is possible but the only 2 that can do it is if Bella's daughter and Jacob have a kid because ヴァンパイア cant have kids but Bella's daughter is half human half vampire so she has human traits too so she should be able to have a chilled and seance Bella's daughter can walk in the 日 and eat human 食 and blood it is an unknown mixture but most likely it would be a vampire able to drink blood and a shape-shifter/werewolf able to eat human 食 he または she might have 2 ability's a normal vampire ability like read mines または a shielder like Bella etc. and the ability to turn to 狼, オオカミ form and the chilled will be a vampire all her live like Bella's daughter and when she stops ageing at maturity which is 17 and then she/he will get her/his ability to turn into a 狼, オオカミ and seance he/she is human, vampire, and werewolf/shape-shifter she/he will most likely age normal but may be 2 years faster than a normal person. like every 年 she/he ages 2 times a 年 instead of once a 年 he/she in human form could have brown eyes and black hair seance Jacob and Bella's daughter has brown eyes and black hair and in 狼, オオカミ form he/she will have ether gold, red, または black eyes depends on what he/she eats または drinks and with brown 毛皮 and a body temperature of a normal human and able to go in the hottest temperatures and the coldest temperatures and stronger and faster than a vampire and a werewolf/shape-shifter and the hybrid 5 scenes will be better than a vampire and a werewolf/shape-shifter and maybe have a 6th scene and the 6th scene would be smartness
