Summary
Disclaimer! I don't own any of the Monsters Vs. Aliens content! All (c) goes to Dreamworks Animation Studios. But all original characters -- Dr. Collins, Molly, William, Dr. Wilson etc... belong to me.
Molly Richardson has always been a character all her own, but her entire life was thrown in another direction when she was bitten by a monster of mysterious origins that turned her into a living nightmare, literally: a teenage werewolf. About 6 months, after an attempted runaway to Las Vegas to find refuge gone horribly wrong, she finds herself in quite a predicament. Miles away from home, in a mysterious government facility and surrounded by five ghoulish monsters and an abrasive military type who welcome her to a whole new life. You know, your average Tuesday afternoon.

Summary
After the SGC is acquired by Area 51.1, a simple mission to escort their former commander, General O'Neill, to his retirement, goes horribly awry...
And this is probably the nicest war-torn land of Ancient superweapons that they've ever encountered.
People are friendly, former religious zealots are peaceful and loving; even the visibly powerful, nigh-magical royalty is surprisingly humble and helpful.
The only problem is... SG-1 and their new commander, the heroine of an alien invasion they were all absent for, are now in a world that they thought was fictitious.
In an instant, their reality is shattered, and replaced with one where magical princesses have the power to not only traverse the universe; but this planet's former nemesis is prepared to help move their entire planet into our neighborhood of the Milky Way...
Revealing Aliens and Monsters to the Earth is one thing, but actual magic, and its wielders, is a whole new level. Even for the Stargate team. -
