A bisexual character has romantic attraction, sexual attraction, or sexual behavior toward both males and females. If they have romantic or sexual attraction to people of any sex or gender identity then they are pansexual.
A bisexual does not necessarily equate to equal sexual attraction to both sexes; commonly, people who have a distinct but not exclusive sexual preference for one sex over the other also identify themselves as bisexual. This is rarely the case as displayed on television, and often characters have their bisexual identity erased.
