One of my favorite backstory to a zords ever

If I were to do a special of "Ponï Zuden sentai Kyoryuger" involving the future team how would you guys think I should do it. I have the characters I just need a story.

This is still in the idea phase so the possibility of me just dropping this idea is still out there so if you got something good please share it. And it can take please in the Pony would or the EQG would.
