Rainbow spirals were superimposed over the eyes of Constantine’s fellow superheroes as he hypnotized them into mindless obedience. Barry swore he had heard those words before, but there was no time to think. “Azerath Metrion Zinthos!” Constantine screamed. He was able to solve the problem through magic, but it was complex and draining, and the dark side saw its chance and took over. It was a big team-up that he was involved in, and Ray, Oliver, and Barry were all assigned to his group. He was able to keep it at bay when he realized what was happening, but a particularly intense mission threw his concentration. But what Constantine never realized was that for every dark side magic spell or incantation that he did, the part of his conscious that wanted him to give into the dark side grew stronger. He used his powers for good, but sometimes it required a sacrifice or something that most others would scoff at.
Dealing in dark magic meant that Constantine always skirted the line between right and wrong.
