Do you mean individual appearances or large group shots?

There is no way we get every Ranger ever. We'll be lucky to see Atleast one guy from Mighty Morphin and that will be Tommy. If for nothing else , because he is willing and the face of MMPR.

The only thing is though, would he be MMPR Green Or White? Also how would they explain him still having his powers? The Green Ranger Powers were theoretically left with tom in the distant past, and the white ranger powers are gone for good. If anything, he could become Zeo Ranger 5 Red because those powers were never "destroyed" they were simply discarded in favor of the turbo powers.

If they bring back past rangers, i would love to see a new forever red/ once a ranger but with less crap XD

Your missing the Black Dino Rangers as well, but those did get burned away...I don't know in my opinion just for Tommy, I feel like as if he should be the only ranger to...Ranger change at least in the Legends War Movie? Pretty much like Gokai change, but just for Tommy since he has a legacy for being 4 different ranger 5 if you want to count Turbo.

Remember that time Tommy returned for the SPD/Dino Thunder crossover?
Or the OTHER SPD/Dino Thunder crossover?
Or that time he was picked for the OO episode Once A Ranger?

Tommy was only mentioned in "Once a Ranger".

I now they already said that Rangers won't return to be substitute teachers. But I still hold out hope JDF comes back as one. Or somehow.

This is gonna sound totally lame to folks here and I know that, but I know very little about Rangers, etc. I am extremely interested in them though. Throughout the years I have purchased them in the stores when I saw something that I liked, but I can't honestly say I've ever sat through and watched an episode. I've run across alot of cool stuff in Japan, and I think it sort of provoked a stronger desire to get a little more involved with the PR series as a whole. So here I am.

Learned about the series from seeing the toys in the store. ((Purchased a few of the Rangers. Black and Pink.)) I honestly believe I am going to sit back and watch the series.

I have looked at alot of it on Wiki, etc, and am failing to 'really' understand what's going on. But I am excited to figure it out over time. So yeah, looks cool to me.

Thuy Trang died years ago. So definitely not going to see every Ranger.

That was Adam not Tommy.
