"Even if I'm defeated, peace won't come. Goblins will rise against humans... what happened today won't prevent that revolution! "
Gundahar is a goblin chief who leads the Goblins. He is one responsible for the recent attacks on the human settlements with new advance technology. He has a strong hatred toward humanity over the past political relations between their two races.
Gundahar is the leader of the Goblins. Not much of his past is known but his war efforts against humanity goes back a long way and his hatred for them is shared mutually with his fellow clansmen. A long history of conflict exist between Goblins and Humans: As far back before the "Crystal Wars" according to Gundahar, Goblins had their civilization of cities before humanity had driven them into the wastelands where they now currently reside. Doctor Vargas had argued back once that it was the Goblins who attacked them first. How long this conflict between the two races had gone on haven't been clarified.
About twenty years ago, the goblins apparently found and rescued Charlotte after she supposedly fell to her death from Dr. Vargas' expedition. Charlotte was raised back to health and soon began helping Gundahar with developing better weapons and armours in fighting against his rival tribes' enemies. After dealing with his enemies among the goblin tribes, Gundahar soon turned Charlotte's works against the humans without her knowledge. As other tribes raids human settlements for sunstones, relics and other valuables, Gundahar trades advance weapons with them to use against their oppressors.
He and Charlotte have a deep bond since she helped them build their armies in their time of need. Gundahar, saved for Charlotte, would like to see the extermination of humanity to order to help the Goblins' reclaim their lost prosperity in their world, rather than make peace with the humans. He had tried explaining to Knack his reasons for war against humanity, both by offering him to join the Goblins or stating that Knack was just a tool to humans. After Knack destroyed the weapons in his factory, Gundahar salvaged whatever remains and fled to rebuild his armies. He vowed that he would return.
