Deuteragonist

A deuteragonist is the second-main character of a story, after the protagonist. The deuteragonist is normally the secondary protagonist of the story.

The deuteragonists of the 3D Universe have a lot in common. They normally start out not getting along well with the protagonist, for example Sweet who blames Carl for their brother and mother's death. They normally come around though seeing they have really redeemed themselves or that both of them have same goals. Most of deuteragonists also accompany the protagonist in the final mission (Ken, Sweet, Salvatore, etc.).

The deuteragonists of the HD Universe have known the protagonist for a long time and have worked with them before. They are normally introduced in the beginning as a close friend or relative to the protagonist.
