OK, here goes...
I don't know Gareth, but I'm familiar with the others... except for 'Zemora'. Who's that? An alternative spelling of 'Zemus', perhaps?

Anyway, Cinna has his unusual charms but is fairly useless, so he'd be out of it quickly - perhaps after eliminating Edward. Zemus is tough, and nearly impervious to Magic, but that smooth criminal Mog would Dance him into submission. Or else use a pointy stick to put holes in him. Either way, Mog's cocky charisma and unique combat strengths would win the day. He'd porbably take care of Gareth pretty quickly, too.
