The Corps, for those who don't know:
Guy Gardener (temporarily)
Von Daggle: Durlan highly experienced GL, known for using his shapeshifting to do dirty tactics. He will, say, turn into a small organism and attack someone from the inside.
R'amey Holl: The butterfly-like lantern there, relatively rookie though not a mook even before her change. Thanks to exposure to the same hyper-evolving comet that gave Captain Comet his powers, she's now semi an energy being (still hurtable physically) with very sharp and dangerous wings, teleportation/creation of wormholes (which she can use to do stuff like put someone half through, then turn it off to cut them in half), and minor telepathy.
I think so.
The main question on who wins is the Annihilators lineup- the addition of weaker people like Wolvie and Capt mean more Alphas, meaning the Lanterns win.
If it's just the core Annihilators, though, then the lanterns might have a bit more power, but the Annihilators have better teamwork (not the Alpha's strong suit) and the edge in some of the individual matches, and they probably win in a very close fight.
