We know that there's many, many, many, MANY Zords there, each of whom can fuel a Ranger - 100 of them, going by Gaoranger. No origin for the Wildzords is given, but they seem similar to the animal Zords created by Ninjor, which were shown to be almost alive. The two set up the floating island to be isolated and to act as a base of operations to save the world if evil won. They never called them in because, by the time things got bad enough to need an army, Zordon was captured and Ninjor was in self-induced exile, and so there was nobody left to pick them up. The scattering of the zords was All Part of the Plan because it would make for improved guerrilla tactics. Presumably, there was some "call the Zords home" button/sigil/spell in the Animarium, but it had been lost to the ages by the time Master Org attacked. They never created the 100-Ranger army because of instructions left by Zordon before his sealing, which over 7,000 years had decayed into legend - instructions to lie low and never call more than five, six max, at a time, presumably to avoid creating too big a morphing grid blip, unless all hope was lost and things were so bad it didn't matter anymore.
- The Wildzords are the descendants of Animus, a LIVING GOD who also happens to be a Megazord. When Animus snaps his fingers, the Wildzords vanish and Shayla goes comatose. Animaria seems to have been an experiment conducted by Animus that got disrupted by the emergence of the Orgs. Now, as seen above, a LOT of fans think the Order of the Claw was set up by Zordon for this reason...
- The Animus problem can be reconciled two ways...
Alternatively...
The loss of Animus is what spurned Ninjor to found the Ninja Academies, so they could provide more assistance to the next person looking to them for aid.
Following Mondo and the rest of the Royal House of Gadgetry's deaths at the end of "Countdown to Destruction", Venjix/Shadowborg decided to attack and destroy both the Power Rangers and the Beetleborgs in revenge for his and Mondo's deaths. Returning to Earth, he soon learned that the kids had returned the Beetle Bonders to Flabber after Zordon's energy wave destroyed the Crustaceans (who had either formed an alliance with the UAE via Astronema or had taken advantage of the invasion of Earth to launch an attack of their own on Charterville). Stealing the Beetle Bonders from under Flabber's nose, Venjix then proceeded to give them to several Cogs that had proven themselves worthy of enduring the Training from Hell he placed on them to test their worthiness of receiving the powers (much like the Mutant Rangers in Season One of MMPR) all for the explicit purpose of conquering the Earth with the aid of the images of those who had thwarted him once before. Upon learning that Lord Zedd had left Serpentera on the Moon, Venjix decided that "the most powerful and evil of all Zords" would be the perfect weapon to use against the Rangers as punishment for Mondo's death and set out with his new army to retrieve it, only to get beaten and destroyed by ten Red Rangers, subsequently being left on the Moon for several years before Alphabet Soup would come along and have one of its scientists convert his remains into a computer virus...
- For extra heartwarming, we'd see Alder reunite with Cole's parents, who had also forgiven him and apologized for not realizing his pain, in the afterlife. Alder would have also accepted Cole's parents together.
There were plans to make it a Shared Universe with Power Rangers that never materialized, but there was a crossover comic with Turbo and the second season implying that the first took place during Zeo. It'd make sense the Machine Empire would be aware of Earth's other heroes and create something to fight them. Thus why Venjix looks like Shadowborg and his allies look like the Beeteborgs: they were made to be Psycho Rangers to them, but were never deployed after the Empire was beaten.
There are two versions of the Gao Knight, the film one and the toy version. Both of them have different zords, with the only common zords being Gao Kong and the Shark. the film version uses the Tiger, Eagle, Elephant, and classic Black Bison, whereas the toy version omits the elephant and replaces the Eagle and the Tiger with a disk (the one the Konga Zord uses when it has the Rhino zord legs) and the soul bird as the waist and left arm respectively.
So which is the correct composition? My guess, neither.
The average Megazord has five zords and the Elephant needs to be a basic part of a Megazord instead of just an upgrade. Also, I like to think the Purple Bison is canon, so that more Megazords can be used at once.
I know they have the same voice actor and thus sound the same, but he had a personality similar to Goldar as well. When Monitor Org was defeated, it was the end of Goldar for good. Or so they thought.
It's hard to say if Zen-Aku would have turned good if he is Duke Org mask hadn't been put on by Merrick-or anyone else on the side of good. Because he and Merrick had shared mental space for the however long it had been since Merrick had put on the mask, some of Merrick's inherent goodness had likely bled over into Zen-Aku's mind; enough so that Zen-Aku started doubting his loyalty to Master Org and enough so to turn him to Wild Force's side.
The Machine Empire could've predicted their destruction by the forces of good, so they created the generals seen in "Forever Red", but didn't activated them yet. The generals were only activated after the Z-Wave was created, thus explaining how they survived it, as they haven't done anything evil in their stasis.
