I'd say it's more based on their name, if it's the name of a group ("army") or the name includes a second one ("& Bulma", "& Ghost", etc.) then they get the Category.

Buu is in LR Hercule's art and Super Attack animation, but not in the card's name, so that LR isn't part of the Category for example.

This "Vegeta / Trunks" card is the first one where the names are separated not by "&" but by "/", as if they were two different cards.
