Marchosias

Marchosias is the sinner form of Adam, the first angel. 

After his "death," Adam ended up falling from grace and found himself transformed into a feral dragon-themed sinner. He was made part of the Ars Goetia due to his original status as "the first angel" and is named a Prince of Hell. As a result, he takes on the name of Marchosias.

As a Prince of Hell, Marchosias is at odds with Charlie. This fact pleases him because he wants nothing more than revenge on Lucifer's daughter-- she was the reason he fell. 

But ironically, Marchosias finds that he enjoys being in Hell. It is absurd and chaotic... but he enjoys the power and control that comes with being a Prince. Compared to Heaven, he has so much more free will and is able to indulge in anything he wants. He forces many sinners into deals with him; relishing in the control he gets over their lives and souls.
Compared to the overlords of the Pride Ring, Marchosias is immensely powerful in his abilities. As a result of his status, he is able to manipulate the "lesser" races of the Pride Ring and ultimately, he lays out the puzzle pieces for creating a grand war between the current overlords. 

• Has the ability to control gravity-- this power allows him to attract and repel matter via gravitation forces... increase and decrease gravity... create black holes and wormholes... and ultimately, create a gravitational field that slow downs and distorts time.

• Marchosias is unable to fly naturally due to many of his original angelic flight feathers being burned away. He makes up for this by making his body weightless using his powers and then gliding.
