By unlocking the Greater Power of a previous team's Ranger Keys, the Gokaigers can access special powers, often activated with GokaiOh, based on the previous Super Sentai teams' mecha; or special powers that power up GokaiOh through gaining approvals from a member of the past Super Sentai teams. Most of the powers manifesting as mechas are completely redesigned and don the Gokaigers' symbol. The unlocking of a Greater Power is signaled when the Ranger Keys of the team that has been unlocked start to glow.
