Adult

The Japanese term for the 4th stage of Digimon evolution is 成熟期 (Seijukuki), which means "Adult Phase". Also known as Champion or Level IV.

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.
