Season 4 will feature a lot more of some characters, including Constantine, and somebody who made an impression as a villain.
The first trailer from San Diego Comic-Con proves that they’ll need all hands on deck to fix time again.
The Legends of Legends of Tomorrow ended Season 3 on both a huge victory with the defeat of Mallus and the discovery of a huge mistake when Constantine turned up with a decapitated dragon’s head to tell them that they basically broke time again.
It was bad news for the shifting Legends (and the people of all time and space in the Arrow-verse), but awesome news for fans who loved these characters’ shenanigans.
