If you want for the ds ones go talk to the Digimon in the town in digimon world dawn and dusk if for digimon world 2 the only one's I know is for snow agumon and veemon also veedramon for veemon you need greymon and airdramon which is gained from digivolving biyomon...Snowagumon is frigimon and veemon or agumon.....
Duftmon can be obtained two way in Digimon Dusk. One way is through GuardiAngemon's DNA Digivolution and the other is through the DNA Digivolution of GrapLeomon.
You can Combine Digimons (DNA digivolution) by using the computer in your home. There is an option called DNA digivolution.Hope that answers your Question :)
You can do it only with DNA digivolution I think... - Grappleomon + Pandamon (LV64+ , Beast EXP50000+, Attack 420+)
IPDramonPM is obtained via the DNA Digivolution of Omnimon and IPDramonFM with both at level 70. Omnimon is a DNA Digivolution of Wargreymon and Metal Gururumon. IPDramonFM is obtained by leveling a Palidramon until it naturally digivolves into it. Palidramon is the DNA Digivolution of ExVeemon and Stingmon both at level 36. IPDramonPM requires a lot of work but is highly considered to be worth the effort.
Depending on their stats certain Digimon can DNA digivolve to become new ones. There used to be a list somewhere but I don't know where it went... EDIT: I use the list from http://forums.supercheats.com/topic.php?topic=74877 which gives a full list of DNA Digivolutions AND an Armor Digivolution list.
In order for this DNA Digivolution to work one of them must be at least level 35, have a Bird Exp of 7000 or more and a Speed stat of 190 or more. The result is a Silphymon.
You may need some requirements to DNA slide a Digimon but just go to the computer a Tamer Home,then use the Digilab Computer.Select a digimon you want to DNA slide and select its digimon partner.Choose DNA digivolve and you get a fused digimon
I think the most powerful digimon is skullgreymon cause nothing cant touch him he's already dead. Other digmon are undead too. I'd say Chronomon HM (holy mode), a bird-like digimon said to be the "strongest digimon in the digimon world" quote from http://digimon.wikia.com/wiki/Chronomon_HM#Chronomon_Holy_Mode He is a DNA ( Jogress ) digivolution of Susanoomon (SuperStarmon and Magnamon) with Valdurmon (Sinduramon and Silphymon). Also, he is the DNA digivolution of two digivolutions. Valdurmon is the "protector of skies" and Susanoomon is the "strongest destructive god" and posseses all 10 elemental attributes. Valdurmon, Susanoomon, and Chronomon HM are all holy attributes.
In the game Digimon World: Dawn and Dusk, a Chronomon Holy Mode can be obtained through DNA digivolution of a Varodutumon and a Susanoomon. Both Digimon must be at level 83 with 100% friendship.
Omnimon/ Omegamon
ExVeemon and Stingmon are to be DNA digivolved to Paildramon. In Dusk and Dawn you need level 35 ExVeemon with 230 attack. Paildramon then naturally digivolves to Imperialdramon and Imperialdramon fighter mode. Imperialdramon FM can DNA digivolve with Omnimon (DNA digivolved of WarGreymon and MetalGarurumon) to become Imperialdramon Paladin Mode, strongest holy digimon in the game. But ZeedMilleniummon is the best digimon in the game, with highest base attack and great skills
Patamon Of course, Patamon refers to TK's digimon in Rookie form. The forms of TK's digimon includes: Fresh/Baby form: Poyomon In-Training: Tokomon (this is the form first encountered by TK) Rookie: Patamon Champion: Angemon Ultimate: MagnaAngemon Mega: Seraphimon Armor Digivolution: Pegasusmon DNA Digivolution: Shakkoumon
