Power Coins (GSA)

The Power Coins are used by the GSA Rangers in the second season of Power Rangers GSA. Their initial purpose was to reawaken the ranger's zords, but ended up being their key to transforming instead of their fingers.

When the GSA's arsenal was infected by Quito, the coins evaporated, leading to it being near impossible to restore these powers.

Similar to Tommy's master morpher, Ashton, Eustus, Charlie, and Kora have Dial Stones which are special Ohman Stones that allow them to access their powers of the past. Since Ashton and Kora have their powers as seen in Legends and Lust and Power Rangers: Sisterhood.
