The Battle of Destral was the conclusion to the Time Slip story arc. It took place when pretty much everyone invaded Destral and tried to kill Blackout. They failed, mainly because DRJ, in what he now feels was a terrible move, forced everyone to skip to the Bara Magna story arc mid-battle. In the end, Blackout took over the MU, and Ynot was displaced into chronospace. More details can be found in user: -Blackout-'s Epic expanding on fight
