There is one tameable creature with this look.
|Boss||Royal Amphitheater, Throne of Thunder (Raid)|
|Retains its original name after taming.|
You may have trouble ending the fight once Horridon is tamed. One option is to feign death, create a group, then leave the group and wait for the 1 minute timer to boot you out of the instance. You may also be locked out of Horridon's arena for a while (30 or more minutes) until the dungeon soft resets.
