I'm tired of this already, so I'll just show the main points that'll allow OS defeat WGM easily:
- WGM fought against many haxed character, like Piedmon and Myotismon. But- he also was defeated by both of these very easily. Against Piedmon he was transformed into a kaychain and remained useless for the rest of the battle (that was settled by HolyAngemon's BFR). MaloMyotismon was a stupider version of Myotismon that WarGreymon couldn't outright beat even while being assisted by MetalGarurumon, in fact, MaloMyotismon was defeated by PIS. The only Darkmasters he defeated were through the use of the much needed Dramon Killers.
- WarGreymon will not be able to use his Tera Force as the atmosphere of the planet will be plagued by OS' Minus Energy. WGM was never shown to be able to use it for his attacks. Possibly, and I mean POSSIBLY BWGM can use it for his attacks, but even this is stretching it a little bit too much.
- WGM cannot fight without Tai's presence. He has to be there in a way or another, be it from a computer or alongside him. If OS decides to blow up the planet, it'll kill Tai and thus WGM would die too? I'm not sure if the partner Digimon dies if the Digi-Destined does, but he'll lose all of his power due to Tai not being there anymore (he has never, in character, fought without Tai, didn't he?). WGM would definetely protect Tai from OS' attacks, but that would give him one heck of a disadvantage as OS has all of those elemental manipulation attacks I pointed out previously.
- OS still has the Dragon Booster, a techinique that resembles more Ginyu's body change than it does Naturon Shenron's absorption, but still, if WGM lets his guard down (something he is prone to somewhat), OS can kill him from the inside, even if he used his Brave Shield to block, Nuova Shenron was using a Energy Shield to block and it still got him, so I'm assuming that if it touches you, you're pretty much done. I could be wrong.
- There's no direct statement that Eis Shenron is Absolute Zero, but there is statement that his ice can freeze Nuova's first form fire that could burn at 6000┬░ C (Nuova was sun-level heat in his "Golden Form") and that his Ice Ray techinique was close to absolute zero. While SIR could very well be AZ level due to it being stronger than the normal IR, I concede that at best Eis and consequentially OS' Ice is near absolute Zero at best. It might still work as even MaloMyostimon got frozen by it, but was still able to get out of it. If WGM was hit by SIR he'd probably only be incapacitated for a few seconds, which is more than enough honestly.
- OS has shown to be a better close-quarters combatant than WGM, and has a much more versatile moveset than the latter, who was reduced to a single attack now that the atmosphere is plagued with Minus Energy, energy that WGM has shown no capability to use for his attacks.
Override might be a problem, though.
And I do have a problem with MegaKabuterimon's feat, that I'll adress in a future thread in the near future now that I have all the time in the world.
