needz moar lloyd. There's a full-blown character 'n moveset hack for 'em after all, KOS-MOS ain't the only fan favorite from Namco. I recall KOS-MOS 'n some other Xeno character makin' a cameo in that crazy JRPG with a bajillion characters too. If Lloyd wasn't in there as well, I wouldn't doubt he'd make it first.
But KOS-MOS is hot, according to Google.
