I believe that it was a Watcher that might have cursed him or something. You know, Vel'Koz might not be a Watcher, but the Watchers could be the same species as Vel'Koz. Maybe Vel'Koz just likes going on solo missions or doesn't like the cold Freljord. It's also possible that Gnar and other ancient yordles were naturally more feral, big and beast-like. Only time will tell.

I wonder if there's a chance that it would be Ezreal (like in the Aatrox teaser) that will explore the ancient caves of the Freljord to find Gnar frozen in ice, and a few days later, Gnar has disappeared, leaving behind him his broken cage of ice.

I also wonder if he'd talk funny and derpy like a caveman "Watchers be kill family, Gnar kill, Gnar no like Watchers.". :P
