[ARSENAL/ATTACK] Evil Crushing Hundred Beast Sword.
When the five main Gaoranger combined their individual weapons, they could form the Evil Crushing Hundred Beast Sword (破邪百獣剣; Haja hyakujuuken). It first appeared in episode 1.
Before Gao Red unleashed the Hundred Beast Sword, he said “Evil spirit begone” (邪鬼退散; Jaki taisan). The kanji “斬” (meaning “cut” or “slash”) appeared on-screen prior to the enemy’s defeat.
