Worlds Collide: The Lightning and the Spark

A freak Spacebridge malfunction tears Bumblebee away from EarthSpark's Malto family and strands him on a parallel Earth. In Central City, Team Flash is finally breathing easy after defeating their greatest speedster threats: Reverse-Flash, Zoom, and Savitar. However, their peace is disrupted when a massive energy surge tracks a mysterious, unregistered yellow muscle car moving at impossible speeds. With no Cybertronians on this Earth, Team Flash assumes Bumblebee is a hostile rogue metahuman or a highly advanced piece of rogue military tech. Stranded and alone, Bumblebee must convince Earth-1's greatest heroes that he is a living, sentient ally before S.T.A.R. Labs locks him away for good.
