Once more with metered rhyme, comes Etrigan the Slayer, just in time! The latest clip from "Justice League Dark," which hails from IGN, puts the spotlight on another member of the team. Like his trademark saying suggests, Etrigan is a centuries-old demon, but his power is bonded to a man named Jason Blood.

In the clip, Constantine uses a spell to force Blood to repeat the saying that releases Etrigan. Blood then transforms into the demon in a blaze of fire storm and becomes a hulking monster with yellow skin, fin-like ears and a sword that can slay other demons.

The sight is enough to intimidate the three demons sent to kill them. "Easy now, brother! We're on the same side, right?" one of the demons chokes out. "Let's use our words," agrees the second. However, Etrigan and the third demon aren't interested in talking things out, and they clash in a battle that makes some of them lose their heads.

A little decapitation can't slow a good demon down, though, and they make it abundantly clear that Constantine will pay for his actions -- but that doesn't seem to phase Constantine in the least as he continues to shove money into a glowing treasure chest.

The clip originally debuted at last year’s New York Comic Con. “There’s a lot of magic, there’s a lot action — it’s superhero stuff with a lot of magic spells,” producer James Tucker explained at the time. “Basically, I asked myself what I would do if I made a ‘Harry Potter’ movie, and that’s basically this film,” added director Jay Oliva.
