Too bad I got here so late. I think good names would be:
banshee
spectre
phantom
Since it's light and kinda has a high pitch electric motor scream to it, but these are taken. Good suggestions guys.
Thinking about cats, here's some that aren't taken and I would like to suggest:
Panthera (a genus of big cats. I like this, since it's a series of vehicles)
Panther
Cougar
Leopard
Caracal
Ocelot
Serval
Wildcat
You guys covered most of the big cat names, missed a few though
Other cool animal names:
Ferret
Wolverine
Grizzly
Mythical creatures:
Minotaur
Manticore
Griffin
Wendigo
Lycan
Centaur
Leviathan
Hydra
Sphinx
Chimera
Basilisk
Anubis
Cerberus
Harpy
Good luck to all!!
