This papercraft is Thrall (birthname Go'el), son of Durotan, the Warchief of the restored orcish Horde and ruler of the red land of Durotar in Kalimdor, based on the MMORPG game World of Warcraft, the paper model is created by Sumerio Anunnaki.
Thrall's parents killed by Gul'dan's assassins shortly after his birth, he was found and raised by Aedelas Blackmoore who gave Thrall his name. Raised as a slave and gladiator, he later joined Orgrim Doomhammer in freeing the orcs imprisoned after the Second War, being named Warchief after Doomhammer's death. After leading the Horde away from the Alliance-claimed Eastern Kingdoms, he rescued and made allies of the Darkspear Trolls and Bloodhoof Tauren. Thrall led the new Horde against their former demonic masters in the Battle of Mount Hyjal. He subsequently led diplomatic efforts at peace between the Horde and Alliance after the end of the Third War.
After the fall of the Lich King and the increasing elemental unrest heralding the Shattering, Thrall stepped down as leader of the Horde, appointed Garrosh Hellscream as Warchief, and joined with the Earthen Ring to combat the rampaging elements, eventually aiding the Aspects in Deathwing's downfall.
With his victory over the corrupted aspect behind him, Thrall had been forced to deal with the chaos his replacement has sewn in his wake. The Pandaria Campaign clearly demonstrated Garrosh's unforeseeable madness and pride, leading to dissention within the Horde itself. Thrall stepped back in to defend the Horde and its allies from their increasingly ruthless dictator. Together with Vol'jin and the other disenfranchised leaders of the Horde, Thrall overthrew his ill-fated successor in the Siege of Orgrimmar. After Garrosh's capture, Thrall personally chose Vol'jin to hold the Horde together and pledged his allegiance to him, along with the remaining leaders of the faction.
During the events of Warlords of Draenor Thrall is a key member of the Horde expedition to the orcish homeworld of Draenor, 35 years in the past. Knowing that Garrosh is responsible for the events in alternate Draenor, Thrall intends to pursue him and bring him down once and for all. [Source: WoWPedia]
