The Brench-Seijin are a species of humanoid aliens in the Dragon Ball series by Akira Toriyama.
The Brench-Seijin origininate from a planet called Planet Brench, which was renamed Coola No. 98 after Cooler took it over. The very high gravity on their home planet makes all Brench-Seijin physically fast and agile when visiting a planet with lower gravity like Namek or Earth. Cooler's henchman Salza is a Brench-Seijin and the Ginyu Force member Jeice is one of them as well.
