"Hey girly player! In your girly gear, with your girly weapons and your girly friends! I am Kologarn and I am going to pump *claps* you up!"
Yes hailing from the great state of California, Kologarn is the 6th boss in Ulduar and he has the muscles to prove it. He is assumed to be a titan himself but I think he's more of the first prototype of the giants. I say this because I think Algalon is the closest thing to a true titan we've seen.
As for the fight, it's not too bad, mainly just a follow what your raid leader says kind of fight. Just watch the adds, kill the arm when it's hurting someone, and AOE adds.
