So I believe his Attack potency should be changed to the follow.
Attack Potency: At least Island level (Its previous evolution, Tankdramon can destroy everything within a radius of 30km), likely Planet level (Comparable to other Mega level Digimon such as BanchoLeomon, ShineGreymon and MirageGaogamon)
(This also scales to his Striking Strength)
Now for his speed.
Speed: Massively Hypersonic+ (equal of shinegreymon) w/ Sub-Relativistic+ reflexes (Digi chosens were able to this much)
His MHS+ feat is legit, but the Sub-Rel+ feat is from a completely different universe so it should be removed.
Edit: You can argue that ShineGreymon kept pace wth Magnamon and WarGreymon so maybe the SubRel+ feat would scale anyway?
And his Durability
Durability:Country level (equal to ShineGreymon), likely Small Planet level via power-scaling
I believe it should just be changed to the follow.
Durability:Planet level (Comparable to the likes of BanchoLeomon, ShineGreymon and MirageGaogamon)
Like a lot of Digimon, Darkdramon has some lore feats which would get its own divider.
Attack Potency:Planet level (Consistently shown to be BanchoLeomon's equal), Universe level with Gigastick Lance (Stated to rival the power of Gallantmons "Gram" according to his databook entry [source]), possibly Universe level (To DNA Digivolve with Kentaurosmon, his power must be somewhat close to his)
Speed: At least Massively Hypersonic+, likely FTL (Should be around as swift as Kentaurosmon)
Durability: At least Planet level, possibly Universe level (On par with BanchoLeomon, who has been implied to have survived battles with the Royal Knights and Three Great Angels [source])
Well, it doesn't really scale to anyone, since its mostly scaling him to others but still. Thoughts? Anything wrong with the post? Feel free to tell me.
