Chapter Summaries

He-El began infusing himself with Barry’s Speed Force and Reverse-Flash’s Negative Speed Force to create his own Speed Force, relying on the Inner Universe within his body. At maximum power, the energy consumed him until he began dispersing into visible molecules, leaving Grodd horrified.
