Vemon and Davis were trying to defeat Wormmon and his partner who were destroying the Digi-World. When they were searching for them Davis came across the Digi-Egg of miracles and that's the story.
If you mean magnamon, go to your digimon pc, select digivolve/degenerate, select armor digivolve, and use the digiegg of miracles of veemon
T.K's partner is Patamon and he could digivolve to Angemon and MagnaAngemon and could also armor digivolve to Pegasusmon, Kari's partner is Gatomon and she can not only digivolve to Angewomon but she can also armor digivolve to Nefertimon, Davis' partner is Veemon who could digivolve to ExVeemon, Paildramon and Imperialdramon and he can also armor digivolve to Flamedramon, Raidramon and Magnamon, Yolei's partner is Hawkmon who could digivolve to Aquilamon and Silphymon and could also armor digivolve to Halsemon and Shurimon, Cody's partner is Armadillomon who could digivolve to Ankylomon and Shakkoumon and he could also digivolve to Digmon and Submarimon and Ken's partner is Wormmon who is capable of digivolving to Stingmon.
If you're playing Digimon World Dawn, then you raise your Veemon's level to 40 and armor digivolve with the digi egg of miracles. If you mean real life.. good luck.
Susanoomon - SuperStarmon + Magnamon - Yatagaramon + Kongoumon (Lv73+, Species EXP88888+, Spirit 460+) Basically u need one of them to be at least level 73 or higher with a TOTAL species exp of 88888 or more and with it's spirit stat at least 460. U can DNA superstarmon and magnamon or u can DNA yatagaramon and kongoumon. I am not 100% sure about how DNA digivolving works cuz I don't do it often myself. I am just starting but I think u can only DNA digivolve digimon that are at most 10 levels apart. So if u r going to DNA Superstarmon and Magnamon and Magnamon is at 73 then superstarmon must be at least level 63 and less than 83. I checked his guide and there is no DNA digimon of mgaogamon + sngreymon. so I guess there is none. I hope this info helps u XD
Veemon/Vmon at level or over and 10000 or more holy expierience (got by defeating holy type digimon) you must have the miracle DE.go to tamer home and digilab PC go into the special digivolve menu and press a on veemon go into armor digivolve and you will get a magnamon
Calumon does not digivolve, he actually makes other digimon digivolve, but he does not.
reptiledramon cant digivolve. it does not digivolve
it does not digivolve because it is a mega
My guess is that it takes a lot of energy for veemon to armor digiviolve into him. Maybe it dissapeared. But I also thought he would because kari said "only a miracle" can help so I thought digiegg of mircles. Also malomyotismon stopped it from happening.
Elecmon is known to digivolve into BlackGarurumon who can digiviolve into ShadowWereGarurummon and then into BlackMetalGarurumon and Elecmon can also digivolve into Leomon who can digivolve into IceLeomon or GrapLeomon and can also slide digivolve into MadLeomon, IceLeomon can digivolve into SaberLeomon or Regulumonm, GrapLeomon can digivolve into SaberLeomon or he could DNA digiviolve with Pandamon in order to become BanchoLeomon. SaberLeomon can additionally digivolve into Dinotigermon.
Digivolve Megadramon or DNA Digivolve MameTyramon and MetalGreymon
It matters about the digimon, if you pass time it might digivolve to another digimon while some of them digivolve to another digimon if you have like 3 or more battles to make it digivolve. for an example: Greymon will digivolve to MetalGreymon with at least 10 battles, or he'll digivolve to MetalGreymon(Virus) if he has 30 Vaccine AP or he'll digivolve to SkullGreymon if you pass time. understand?
