User blog comment:Steel Scarlet Spider/Identity Crisis - Zoom/@comment-3481504-20151204012103

Seeing as Constantine is now apart of the Arrowverse, maybe Zoom is actually a demon with the Speed-Force, and they'll need Constantine and Cisco's help to take him down. Just a thought, however, I think it's more likely that Zoom is E-2 Henry and captured E-1 Henry and took his place.
