Re: How did Rita end up with the Dragon Coin?
 

The Dragon Coin was hidden separately. Probably with the Dragonzord. Rita found them after Zordon found his coins. She didn't want Zordon to get too much of an advantage.

I believe they both found the coins and had a fight,...Zordon got five and Rita one.

I think Lord Zedd gave her the coin. Which was part of why he was so mad at her in Mutiny. She lost the Dragon Coin. And it was also why he went after Tommy so hard.

I always thought she created it using the power of the Dragonzord and the Wizard of Deception.

Maybe Ninjor created two sets of Dino Coins - ones that come with Ranger suits with sheilds alike that of the Green Ranger and the regular, sheild-less ones. The sheild-less powers were much more stable and for some reason, inaccessible to Rita, which was not the case with the sheild-based version of the powers. Because none of the powers were meant for evil use, Rita's versions of the Dino powers quickly ran out because her evil magic was causing power issues. Since she only experiemnted with the 5 main sheild-based versions of the Dino powers, the Dragon coin from her set remained intact. The other version of the Dragon coin was lost during a battle and was never found, destroyed or was never even made.

Since Ninjor did create all of the power coins, this explaines how are the Dragonzord and the other 5 Dinozords completely compatible for Megazord combinations.

And since Tommy is now in control of the Green Ranger Powers and since there is no more Rita's evil magic, the Dragon coin had returned to full power and its full potential.

I really like that idea. It would have been cool to see two separate Ranger teams in action. Even if it was just a flashback.

Another take on that would be that Rita defeated a team of Dragon Rangers and the Green coin was all that was left. Rita took it for her own use later on. The powers were created by Ninjor took, so GreenRanger was compatible with the five coins on Earth.
