About the Flash #20 Cover A Mike Del Mundo

A NEW FLASH EVENT BEGINS: BAD MOON RISING The moon has become a battleground in the war to end all wars. On one side: Wally West. And Wally West. And Wally West. Using his newfound powerset gained after the Justice League's battle with Darkseid, he's split himself hundreds of times, into an army of TEMPS, as Wally keeps going while spreading himself thinner and thinner. On the other side: Eclipso, reborn in a terrifying new form. After razing Skartaris, he's built a new army, and taken control of the Moon, in his quest to replace Darkseid as the ultimate expression of existential evil. But, Eclipso isn't the only one attempting the fill the void left by Darkseid's death, as the Temp Wally on the Watchtower with the Justice League is fast learning... It's a rumble over all sides of the Moon, as the ALL IN era of the Fastest Man Alive enters its first event: Bad Moon Rising!
