So, who were they cameos of? Only one I can think of is Klarth. T.T Yeah, I'm pathetic for not recognizing their hats ; ;

There's a KOS-MOS one that uses a parody of X-Buster.

There were four Tales hats for the Gentlemen, I believe. Klarth, Ras, Hilda, and Chloe.

That KOS-MOS one is a jerk. Insane Evasion and Defense.
