Is her Real name amara or alison?

I think it was established that it wasn't in fact a lie.

do you know what book(s) that happened in?

nope, sorry

X-Treme X-Men 46

as far as i know her name is amara.

Wow... I'm not one for bumping old threads, but this was never really answered.

She was introduced as Amara.  Amy is a casual & shortened form of Amara.  Cannonball did go through a short pase of calling her Mara, but she told him to stop since it was too informal (I believe she said it was the way a lover would address her).

However, after the Hellions were killed by Trevor Fitzroy, Cannonball, Warpath & Firestar ventured into the Amazonian jungles to reach Nova Roma.  They wanted to tell Amara & Empath about the fate of their former Hellion team-mates.  There they found everyone was in a slight daze.  Empath had been controling everyone. 

It turned out that Nova Roma was a fake.  When Selene left the city her spells began to crumble and the people there began to remember their old lives.  They had been kidnapped and given new Roman identities.  Empath had grown to love Nova Roma and wanted it to stay as it was, so he'd been using his own powers to keep it the way that it was. 

So Amara was never really Amara.  She was Alison Crestmere, who had been kidnapped from her family in England when she was a baby. 

That was in New Warriors #31.  However, despite claiming that she was going to find her original family, she never did... and people still kept calling her Amara, since that was how they'd known her for years.  But I think in comics they might have retconned it since.  She was Alison Crestmere in the X-Men: Legends game.  Either way, everyone still knows her as Amara :)

OH WOW.... I had no idea Nova Roma was fake.... wow, thanks Kitty!

@Eyelash30: Marvel have ignored-retconned that back out of continuity, preferring to keep her as Amara instead of Alison.

The X-Men: Evolution cartoon, ComicVine's database and the Marvel databases (though unofficial) use the name Amara Aquilla as the real name and Alison Crestmere as the alias.

When Claremont was writing X-Treme X-Men it was revealed that the Nova Roma was in fact real, and the fact that they were all brainwashed was the lie.

Yeah, it was a petty "I don't like other writers playing with my characters!" storyline ;) So he retconned it back & now everyone just conveniently ignores that little 'hiccup' in her history.

The worst part for me was in the issue where Amara said that Nova Roma was real she also said they aren't completely backwards, they even have the internet.....huh wha?

Ha ha! Yeah, the best way to integrate an ancient civilisation into the 21st Century is pipe the internet through the dense & protected Amazonian rainforest ;)
