So we know Chronomon > Yggdrasil for a fact. However, Digimon World DS SGDL >>> Chronomon in DS. However, ChaosGrimmon manipulatied a Dimension equal in size to the Digital World Effortlessly. ExoGrimmon is >>>>>than that. It says he should be in the same league on the file, but in truth ExoGrimmon should be >>Chronomon. Also, I should note that destroying everything in the digital world includes the Memorial Stelia and Dark Area which exists outside of the multiverse (As if Lucemon would accept that shit). As shown in Cyber Sleuth, Ygg can even effect
Dimensional Entities and reformat them. And Chronomon is strong enough to destroy Yggdrasil for good. And then we have the fact that GAIA Origin Alphamon, like all of the other members did not even see ExoGrimmon, Chronomon nor the SGDL as sufficient threat for them to even remotely get involved.
In Cyber Sleuth, we know Sayo and Takumi are comparable. As such we know the Cyber Sleuth Demon Lords to be above the likes of the Digimon World: DS ones seeing as Protag-Kun from DS killed all seven and then off screen, Sayo killed all seven, stronger versions. And as confirmed by Mirei, killing the SGDL in one world, grants them strength in every other. This means the CS Demon Lords got TWO large boosts in power. Not to mention all the times the Demon Lords have died in the Anime or Manga. Now, this is a good way to gauge how strong Post-Game/Endgame Takumi is and how strong Mother Eater is. It should be noted that Takumi chronologically does these fights right before Mother Eater, and Mother Eater at this point is considered to be the largest threat outside of Re
igitze stuff. Or is it?
I should note that the Alphamon in Cyber Sleuth is the same one from, Re
igitize and Saga-X, as such he carries his feats from there as well over to Cyber Sleuth. In Re
igitize, they made it pretty clear that in truth, Alphamon is leagues above even the X-Antibody Royal Knights. The X-Antibody Knights are so much more powerful than the base Royal Knights, that the base Knights cannot hope to compare. And on the way to face Yggdrasil, Alphamon and Taiga's WarGreymon easily dispatched multiple clones of the X-Antibody Knights who were a good deal stronger than the originals. And then still had enough power to face a Powered-Up Yggdrasil with WarGreymon. And I should note this is an Alphamon who had already given his Digicore away. So he may or may not have been weaker than his prime.
Back to Cyber Sleuth, Takumi has a mission in which he fights clones of all the Royal Knights, including Alphamon. (Note that Takumi likely has a team of 11 Digimon) and after he defeats them, Kyoko (Alphamon) reminds Takumi that the clone of the Alphamon he fought in nothing compared to the real deal. And then there is the fact that Alphamon helped fight Mother Eater and tanked Yggdrasil's Multiversal reset like it's nothing. I should note that Yggdrasil resetted both the Human AND Digimon Multiverses. Both of which are infinite.
>Gasps for air
I think that's all. And I believe I got everything right.
