King Kong
Godzilla
The Blob
and a herd of xenomorph's
pretty much world killlers

I like your outside the box thinking, but no Predator?

Not strictly horror, but the T-1008 and ED-209 would be a pretty formidable double-team – as long as there were no stairs, of course, that would be disastrous for one of them!

I thought it was supposed to be a team of people from horror films that help kill off the evil creatures? i woud love to see a film where the military get help from 'The Blob' to defend the planet from something evil! holy crap that would be a great film!

That was just me who ran with that idea.

As for King Kong and Godzilla, they'd be no use as they'd just fight each other. ;)

Dem i will be honest, since Secondary school i have dreamed of seeing a horror all-star film where the best of the worst horror maniacs take on a small town and turn it into a living hell. That would be a super awesome film if it was made well.
