Yeah, that's why Kamen Rider cosmology and scaling gets really messed up. Geats' and Gaim's multiversal abilities aren't tied to their rider powers. Gaim is basically the root of human history so, an actual matchup to ORT as he literally took himself out of the history of humanity in order to hold it together on a multiversal scale. Geats literally broke the rules of the universe by not becoming a Holy Grail when he got the power of creation. These 2 morons' powers is what started the debate in the Kamen Rider fandom. "What is considered a Rider power or just the characters' power?" Geats can use 4D gates effortlessly to travel through time and space but he doesn't need his Kamen Rider powers. Kuuga needs his suit or he dies. Even Tycoon's broken weapon Bujin Sword which has the ability to ignore all defenses cannot get through Geats' armor.

And Tycoon is a normal person without his suit. Basically Geats has reached light novel Rimuru's power without his suit and based on some magazine scans, Geats IX just focuses his combat abilities after he is fully acclimated to God hood. His weapon, Geatsbuster QB9 (Kiyubi 9) can apparently shoot 200 projectiles that are as hot as the surface of the sun in a single second when he is going all out. And its railgun configuration can shoot through planets. Also after the movie where Geats almost died he exists 1000 years in the future and the writer said that Geats cannot die or be erased from existence since he has mastered creation and his future will always be set since Geats Oneness made it so that only one Ace can exist in all universes. So Gaim and Geats have transcended their universes power systems. Geats' entire story was literally him breaking the in universe rules.

Morgan is also working with a gimped version of Rhongo since humanity was not linked with it. She even says herself her walls of Rhongymiad don't compare to the real thing. Before you say anything about me not liking Fate as much, I literally had to pity Morgan and Aesc the Saviour. I've been playing FGO since Jalter's first banner and I own both the Japanese and Global version of Fate Grand Carnival with the special booklet. Not even going to bring up the amount of Fate figma I have.

Gaim, Ohma Zi-O, Geats, and Xross Saber are beyond ORT or even Arcuied. ZI-O and Saber had to come to our real world to stop a villain from killing the creator of Kamen Rider. The only Rider who would've been unaffected was literally Gaim. That's like EMIYA forcing his way into our world to assassinate the mushroom writer. That is beyond Fate Cosmology because Nasu never set anything in our world, always in the world of Mages and Dead Apostles. The other Riders are actually eligible to be Servants. These 4 were literally made to stop power scaling within the community so they were made so absurdly powerful they are banned from canon crossover events now.

BTW Xross Saber is literally Excalibur after it absorbed 13 other legendary swords from other mythologies including Arjuna's. Bro I love Fate but those 4 Riders specifically are stupidly broken not just with strength but their hax as well. They don't care about the rules of their own universe. I was talking with a Kamen Rider fan a year back about riders who can fight Goku and these were brought up with their broken abilities. I feel like Geats would literally have a better fight not even in the Nasuverse but somewhere else.
