Jihørd
He awoke slowly, chained heavily to the antifreeze wall in his chamber, as he regained consciousness he felt his rage build in his chest. He knew where he was, he knew why he was thee, and he knew he was a prisoner. He had always been one of their more... Aggressive specimens, and was extremely surprised to see his normal security onslaught of robots were slewn in prices across the floor. As his rage built, he began to roar, bellow and scream with anger, straining against his chains until they began to snap.
"EXLRA! WEB! GRIHOD!"
he roared, calling for the few names in his head.
The thing about a frost Giant's scream is that it didn't belong in midgard, and every cell in this cursed realm was programmed to understand that he shouldn't be there, and that he, above all else, should be feared.
"GET ME OUT OF THIS DAMNED CELL!"
He roared, his voice echoing throughout the pyramid, many of the older specimens would recognize his roar, as it was heard every few decades, when he woke. The security of this realm wasn't meant to contain his species, and rarely did it. The only way the robots were capable of keeping him asleep was by superheating his cell, and they were unable to keep the furnaces running non-stop, so every time they were turned off for cooling, he awoke, as well as his rage.
