You have to go to macro sea from access glacier and enter a tube to get to the center of access glacier and fight ophanimon (you think you're going to fight grimmon)
You can digivolve it from GeoGreymon I believe (or was that Black Tyrannomon?) normally, but you need to have 100% scan data to get it in any form I believe ("gotSkullGreymon").
A3:
Digimon matchmake two dark digimon and it should be apearing a kaizer digiegg thats skullgreymon
A4:
Start by training a Betamon and after a while it will digivlove into Blackagumon, but choose the top part to digivlove it into dark tryannomon and then skullgremon -Answer by:zero56
A5:
Match make a level 40 dragon and level 40 dark digimon
When you fight digimon you automatically get scan data then when you get 100% you go back to your home room and go to the digilab where you go to the first option and choose the digimon and then you have it.
Q:How do you defeat the mega level digimon that are found after you defeat the gaia origin challenge most of my digimon are in the 50s-80s yet they still beat me with ease?
A1:
You use yore attacks over and over again you also need a clumon to keep reviving your digimon and 6 lv. 76 digimon or above.
A2:
Wrong you need to use your most powerfull attaks to defeat them you migth need many digirevivers
A3:
Also use attacks that hit multiple times like lillymon's flower cannon
A4:
You need to degenerate them to ultimate and retrain to full power and then digivolve them to mega then train some more this will make you the most powerful trainer possible like me.
In dawn it forces you to get him but in dusk you can only get him by trade through wi-fi OR digimon matching through wireless connections. Apollomon and Dianamon they make a baby egg. if you want chonromon get holy exp first it will hatch as a sunmon for lunamon do the same thing just give it dark exp first. hope it helps
