@FerrousMaelstrom, Also my apologies if I came off too abrasive. I have some people on ignore because they aren't worth reading on what they say, so I may have misread your post, and for that I apologize.


With Build, sparkling is a mid-tier form. Build is a different kind of series emphasis though than OOOs. Build deals with the industrial war complex, and has a very literal arms race and the cost of fighting in the themes. Hazard form itself speaks to this, as does the gel system, and the aspects of bringing it all under control as we get to Rabbit Rabbit and Tank Tank, until finally reaching genius form. Build also deals in heavy sub tones of the cost of warfare and inventions on the inventor itself, and many other themes that all coalesce into each other to make for a very great show in itself. Each show obviously has their own builds and emphasis and how their individual tiers work. How that's going to translate to Zi-O for each series is half the fun of the show as a 20th series celebration to end an era and begin the next.

With that being said, how strong fan responses are to Hazard forms, we might see something on that later. For heroic standpoints though, Sparkling and Genius make the most sense for immediate likely in connotations of Zi-O and Geiz, besides other add-ons later and side material or other side riders. Some of which may or may not end up being toy only. But they did manage to work Genm into the show. So we could see more still too in the way of side rider stuff. But there is a lot that'll likely be game related only merchandise too because of each show's own inherent hype and fanbases.

Ehhhhh, what made Hazard popular was that it kept Build's diverse toolkit unlike the other upgrades and was shown to be an incredibly dangerous obstacle Sento had to overcome, even after Sento made some upgrades which cancelled out the berserk effect, he was still at risk of going berserk with just Hazard, not to mention Hazard's design is incredible as it doesn't just look cool but shows us it's not quite right and dangerous

Seeing this reminds me how red felt like quite the dominant color for the first decade of Heisei riders. Even the ones where red was not the main color there was at least a pinch of red somewhere on the suits, be it the eyes, markings on the suit, etc.

I think a big issue was the late Hibiki->Kiva era. It seemed like once toy sales slipped they doubled down on red for the main Rider, since they're used to red selling better due to Sentai.

All Hibiki upgrades were red, Kabuto, Den-O and Kiva were red. Even Decade likely only wasn't actually red because he'd be appearing alongside so many red suits, so they changed the tone slightly to make him stand out more.

Even before that red was featured pretty heavily. Kuuga Mighty and Rising Mighty, Agito Burning, Ryuki and Ryuki Survive, Faiz Blaster all featured Red in some major form or fashion. You're probably right though on Red selling better though.

I've read somewhere the Toei higher ups wanted to make Double red for precisely these reasons, and the designers had to appeal to Ichigou and Nigou for a green/black colour scheme. Of course, they also made Accel, so who knows.

Yeah, red is seen as a 'heroic' colour, which is why Sentai reds always get the most focus out of the team

So was the Decadriver always pink or?

I'm guessing it's an updated version; judging by the Heisei Phase 2 forms. Look out for a toy release soon
