LOL do you want us to put bios in here, or just in there? And do you want a traditional alien invasion name or something more creative? As to age ranges, it might be fun not to limit that, a crusty old military man/woman might be a fun mix if there's a lot of younger kids, or a really young child or somesuch.

Traditional:
The Arrival
The Invasion
Not in Peace

Creative:
Mana and Mayhem
Rechanneled
UFAAM(United Forces against alien mana)

off to work now, I'll think about my character bio there and get back ta ya.
