I've been thinking, that if ever they're was the possibility Stacey gets a power-up, I reckon it'll be TopGaler inspired, just to complete the trio of deceased 6th ranger mechas, plus it would go with his character on how he was an evil ranger for most of the run.

Minipla Super Vroon!

I feel like it'd also be Basco-themed, since he can already summon evil rangers.

If they were smart they would have Stacey summon "Evil Mecha" instead of reusing "Good Sentai Mecha"! Have him summon Giga Volt (Liveman), Dora Talos (Zyuranger), BraKing (Carranger), Nova (Timeranger), Jakiryuu Grand (Boukenger), and/or Hades Machine Golem (Magiranger)!

Can I take a quick second to say how much I appreciate the effort put into these, by the way? They're just meant to be little promos for the new toys, but it's like someone realized that's already what the show is, and decided to make every one a surprisingly fleshed-out little mini Zenkaiger episode. It's genuinely a nice treat whenever one of these comes out.

Hmm, I wonder. So, we know that the final thing that will be released in Q4 of Zenkaiger is the Zenryoku Zenkai Cannon. It is reported to have a spaceship or some other craft mode, a Cannon Mode, a Robot Mode, I think, and, of course, the Combined mode. So, hmm. Here is some speculation on my part. It will sound like I'm describing the Mecha or I'm a Leaker, but this is pure speculation.

So, I think that the Spaceship mode might take inspiration from the Variblune, the Varidorin, and/or Sky Ace, considering that Zenkaiser is based upon both Akarenger/Akaranger and Big One.

Meanwhile, its cannon mode would be based upon a gun similar to the Geartlinger/ Geardalinger/Geartozinger which can plug into the Geartlinger, sort of like Lupinranger vs Patranger's Lupin Magnum.

In the separate Robot Mode, if it has one, I think it might resemble DaiDenzin/ Denzi Fighter from Denshi Sentai Denziman, the First Mecha that transformed into a Robo, and/or the Taiyo Gattai Sun Vulcan Robo from Taiyo Sentai Sun Vulcan, the first Robo that is a combination of multiple Mecha, Cosmo Vulcan and Bull Vulcan.

In the combined "ZenkaiOh" mode, the Left from the ZenkaiOh mode side of the helmet would have a bird head, like part of the Variblune/Varidorin, sticking up to mirror the Dragon Caesar Part on the Right Side of ZenkaiOh Superxxxxx.

In its Mecha Form, it would serve as a ship for the Kikainoid Zenkaigers (Juran, Gaon, Magine, and Vroon) and combines their powers. When combined into the ZenkaiOh-styled form, it would give the Zenkaigers the traditional Cockpit design of multiple Sentai Members sitting in a single cockpit.

Now, there could be something a bit special about this Cannon. Possibly, it could allow for the Cluster Combination. You know, the used-to-be signature final combination of all the Mecha. The Revolver Tenrai Senpuujin, the Ultimate Daibouken, the SaiDaiGekiRinTohja, the Engine-O G12, the Kyoryu SamuraiHaOh, the ToQ Rainbow, the HaOh Shurikenjin. That.

Note: What I just described is total speculation. It may be true, it may be false. Who knows? I don't.

I would also like to see Balzion, Killer Oh, Wolkaizer, Megazord Epsilon and Smog Jouki!

Well it happened in Magiranger, so yeah I guess it's possible for the Zenkaigers to share a cockpit while also being the mecha they're piloting.

You say that like clusterfudge mecha are going out of fashion or something. As recently as 2018, there was the awesome Good Cool Kaizer VSX which was so clustery that it was CGI exclusive!

What’s a good appropriate PR title for Zenkaiger?

Anything since “Mighty Morphin Alien Rangers”.

Power Rangers Revolution? Since gears revolve and if the plot is similar, they could be leading a revolution against the world-conquering bad guys.

Revolution seems appropriate I guess. Or…

“Mighty Morphin Mecha Rangers”? Due to the Rangers being machines?
