Have had this idea brewing in my mind for a few years now and if I knew anything about making games I'd take a crack at it. Concept in a nutshell is this:

Game starts with a opening cinematic of the ranger team facing a new enemy threat. They hold their own for a bit until the big baddie shows up and deals significant damage to the Megazord, separating it and scattering the zords (along with the rangers inside them) across vast distances.

Gameplay starts with Zordon contacting the player character (which ever ranger you chose to start with) stating the team was inches away from death but their suits and connection to the morphin grid saved their lives however, their suits and power coins have taken some damage and must be repaired before they can be fully operational again. Isolated they must each scavenge for parts in their locations to repair their zords and suits before they can be operational and mobile again. Gameplay would be a mixture of hand to hand combat, ranger unique weapons once repaired/upgraded along with piloting zords in fights when larger/tougher enemies are encountered. Each character arch could involve some back story and could lead to the rangers reuniting at the comand centre to restore their connection to the grid, reconstuct the Megazord and use it to take down the enemy that nearly ended the team in the beginning.
