Partners in Training (also called Partners in Justice) are a duo or trio of good guys who work together bringing justice. Many duos/trios are sidekicks to the Big Good and are sometimes bumbling. They almost always seem to get along and like each other but sometimes they do have problems with each other. Trios are also acceptable, such as Yao, Ling, and Chien Po, or the Powerpuff Girls.

Note: Add only duos or trios to this category. Individual heroes and teams of more than three heroes do not count. Mutant Toys are the exception.

These heroes can be pure good if (in duos and trios' cases) all 2 or 3 of the members meet the criteria to qualify for the category.
