Much like how we didn't get Zi-O's final form until the final episode too!

If you considered Ohma Zi-O to be final form of Zi-O, what do you considered GrandZi-O as?

GrandZi-O is his final form BTW

oh hey 100 pages finally
iwaeee

Depends on how you look at it, Zi-O's got two Upgrade Routes

Route 1 is the Legend Powers, Decade being the Upgrade Form and Grand being the Super Form

Route 2 is his own powers growing, Zi-O II is the upgrade and Zi-O Trinity is the Super Form.

Both routes merge into Oma Zi-O, so if you wanna get technical. Oma Zi-O is his true final form.

Kind of like how the Oma Zi-O and Geiz Revive timelines merge to create a composite timeline on the Day of Oma? That's an interesting way of looking at it and makes sense considering the original Oma Zi-O didn't even have Trinity. Oma Form in Over Quartzer could be the extra final form after Sougo receives all the powers from his alternate selves.

Maybe we should just do away with the concept of a final form. I understand the need for them to sell merchandise, but man I miss just a classic suit and accessories.

A lot of these power-ups and forms end up being pointless with the many times Riders end up fighting their final fight in their base forms. In Sentai's case the Rangers either finish the fight in their base forms or in civilian form armed with nothing but plot armor and character shields.

To be fair, it's justifiable in some cases, like how in Ex-Aid they used the base forms to remind everyone how much of a horrid fighter Cronus is without his time stop ability, or in Fourze where it's after beating the Sagittarius Zodiarts with all of his forms before using his final form, or how in Build both Evolt and Build were devolving into their weaker forms (though I can't explain why Build turned into RabbitDragon that then turned into RabbitTank, since that's a little inexplicable).

It's debatable when Kamen Rider reached the point of excess with toys (I'd argue somewhere between Wizard and Drive; with W through Fourze managing a very good compromise), but it most certainly is at that point now. Many recent series I could point out a form and a toy that you could very easily have cut and lost little if nothing of significance -- Rabbit/Tank Sparkling; Brave Legacy; Zero-One Shining Assault Hopper... even series with a lot of forms that do manage to have thematic relevance (all of Ghost's upgrades, for instance) it's not hard to imagine that the series would have been even better off with less of them.

It's an issue I've kind of learned to live with, but it does still bug me especially when it becomes predictable what pattern we'll follow and how quickly The Newest Most Powerful Form Evar will fall into irrelevance. I love Build a lot, but Too Many Toys is most certainly an issue with it that I keep grappling with.

I think Ex-Aid has been the worst thus far. From Episode 1 to 27, in every episode there is either a: New Rider, New Form, New Toy or a foreshadowing of a new toy. A quick look through the episode, I'd say 10 out of the 45 episode of Ex-Aid don't introduce or tease anything except for story details.
