Vademon

Vademon
Vademon is an Alien Digimon whose name is derived from "Invader". It is shaped like something that came from the far reaches of the cosmos, but it's rumored that it was born from the seed of a plant. It is unimaginable from its enormously developed head and octopus-like lower body, but it carries a dreadful offensive power.

Digimon Adventure
When Koushiro "Izzy" Izumi and Tentomon fell into his pocket dimension, Vademon convinced Izzy to give up his curiosity (his heart in the Japanese version) but Pabumon helped Izzy get it back. But at the same time, DemiDevimon wanted Vademon to sell him Izzy's crest. A fight ensued and resulted with Kabuterimon Digivolving to MegaKabuterimon and beating Vademon, collapsing his pocket dimension.

Digimon Frontier
A Vademon worked as a fortune teller at the Fortune Teller Village while other Vademon were seen at the Autumn Leaf Fair and the Great Trailmon Race.

Digimon Data Squad
A Vademon was seen in a glass tube in the room where Thomas H. Norstein's sister was in.

Digimon World
Vademon's bottom half is in a UFO due to tentacle rendering difficulties. He joins the restaurant. Vademon is also a playable character. If a certain period of time elapses and your champion hasn't reached required stats to digivolve into a certain other digimon, it shall digivolve into Vademon. Vademon is also the only ultimate in the game which can digivolve from any champion.

Digimon World 2
Vademon digivolves from Guardromon, PlatinumSukamon and Raremon depending on its DP.

Digimon World 3
Vademon can be found in Asuka's West Sector, in Mobius Desert. His red variations can also be found in the same place in Amaterasu Server. As with in Digimon World, Vademon's bottom half is encased in a UFO. He is also available as a Brown Ultimate Card with 24/22.

Digimon Digital Card Battle
Vademon belongs to the Rare card group.

Digimon World Dawn/Dusk
Vademon can obtained by DNA digivolve with RedVegiemon + Nanimon (Lv36+, Machine EXP 3000+, Insect/Plant EXP 4000+).

Digimon World Championship
Many champion-level digimon, such as Starmon or Vegiemon are capable of digivolving into Vademon, which is unfortunate because Vademon is one of the few digimon who are unable to evolve.

Vademon X
Vademon X is an Alien Digimon and a carrier of the X Antibody whose name is derived from "Invader". It is shaped like something that came from the far reaches of the cosmos, but it's rumored that it was born from the seed of a plant. It is unimaginable from its enormously developed head and octopus-like lower body, but it carries a dreadful offensive power. Due to the X-Antibody, it became the "Defective Alien". Unlike the other Vademon which came in order to invade the Earth, it appears in a shape which has an adverse effect on Earth culture. It thinks that it is the stronger evolution, but that is only looks, as it's hard for it to see the truth through its sunglasses. However, it is able to master skills which menace enemy Digimon, and is perhaps a step closer to invading the Earth.
