Baby II

The Japanese term for the 1st and 2nd stage of Digimon evolution is 幼年期 (Younenki), which means "Baby Phase". The 2nd such phase is also known as In-Training or Level II.

They are slightly stronger and more developed than newborn Digimon, and usually grow limbs of some sort to become more mobile than their blob-like previous forms. Most of them are of the Data type and attack using bubbles or some other mildly offensive technique.

They evolve somewhat swiftly into the Child stage. Some Younenki II Digimon sometimes only have one form to evolve into - which usually happens when they're created to be the Baby of a Digimon created for the anime. Mostly, they have branching evolutions that can range from two to six options with most Children branching out into Virus, Data, and Vaccine forms.

Some Digimon skip this stage, and Younenki I as well, and will hatch directly into the Child stage from the DigiTama.

Younenki II Digimon, like Younenki I, don't appear in the TCG cards, aside from minor illustrations on Option Cards. The single exception to this is Culumon, who has several cards of his own, although they're intended to be played as evolution-inducing option cards rather than be used in battle.
