Confrontation Beast-Fist Akugata (臨獣拳アクガタ Rin Jūken Akugata) is a fictional school of martial arts practiced by the antagonists in the series Juken Sentai Gekiranger. This martial arts school focuses on the principles of natural selection, that only those strong enough can survive the harsh and inhuman training while fully mastering the Akugata's fighting styles. Those that master it obtain their power from the negative feelings of the weak they prey on, making it into Confrontation Ki a form of Qi that is Fierce Ki's polar opposite and brought about by the darkness in one's heart, used by the Akugata's members to perform Ringi. The ultimate form of Confrontation Ki is the Fury Confrontation Ki manifested through infinite rage and a desire to destroy everything.
