Blackbriar Thorn is a  and one of the most powerful magicians in the world.
Blackbriar Thorn's skin is brown and appears to be made of some form of plant. He has a white beard and fierce red eyes.
His entire attire evokes nature: he wears twig sandals, a long dark green skirt resembling foliage, and a ragged brown open vest.
Blackbriar Thorn and the other sorcerers guarded the pentagram in the adult dimension. When the Justice League arrived, he trapped Batman in a giant tree, but it did not hold him for long. He then joined the other wizards who tried to break Zatara's force field. He was taken out by Doctor Fate after the worlds were merged back together.
