Adult

Adult (成熟期 Seijukuki) is the term used which refers to the 4th stage of Digimon evolution, also referred to as level IV. (Dub: Champion).

Almost all Digimon reach this stage of evolution, which is proceeded by the "Child Phase" stage. Continuing on to "Perfect Body" before death from old age is usually a challenge, especially in the earlier virtual pets.

In every medium outside of the anime, Seijukuki Digimon are the most common stage the average Digimon will be encountered at. Their shape and size varies wildly, although the average would problably be about the size of a real-life elephant or dinosaur.
