Legends of Tomorrow is created in order to continue the stories from the Heroes Join Forces crossover event with recurring characters from Arrow and The Flash serving as the starring cast. The series later continued multiple stories from cancelled or completed series, such as Mari McCabe from Vixen and John Constantine from Constantine. The latter also served as a regular character from the fourth to sixth season after recurring in the third season. However, Constantine departed the series in the sixth season while Matt Ryan appeared as an alternate character in the seventh season. Aside from the Arrowverse, Legends of Tomorrow also has loose ties to the DC Extended Universe, with Bodhi Sabongui, who portrayed a young Behrad Tomaz, reprising the character's alternate counterpart named Amon Tomaz in Black Adam.
