The Hybrid bear is the last villain appearing in Ginga Densetsu Weed. He is presumed to be a mix between a grizzly and a polar bear and he was the largest of the three hybrid bears seen in the manga.

He arrives to avenge his cub, the Hybrid Grizzly bear who was killed by Joe. The Hybrid bear fights Weed and Joe's pack for a long time and kills off Liger, Jack and Guilder. The dogs try to push Hybrid bear off a cliff but he climbs back every time to continue the fight. The bear also kills GB who sacrificed himself to protect Weed.

After GB's deatd, Weed, Jerome and Joe permorm a final attack on Hybrid. Weed uses Zetsu Tenrou Battouga and him, Jerome and the bear fall into the river. Hybrid bear was ither killed by Weed's battouga or drowned in the river, as the last panel featuring him shows his dead body in the stuck on the dam.
