DC x Sonic the Hedgehog Metal Legion #3

Enter the Metal Legion! Dr. Eggman and the Legion of Doom have won! The Justice League, Sonic the Hedgehog, and his friends have been banished from reality.

Now nothing stands in the way of the villains' sinister plans — except themselves! One betrayal follows another as the bad guys slide into open war — and two worlds end up caught in the crossfire.
