Abducted from their planet millennia ago, the Triceratons are at last
free to return home. They come in peace, but how will the world react
to a Triceraton "invasion" in the heart of New York City? About how
you would expect, especially when the Earth Protection Force gets
involved. As the three-pronged attack begins in earnest, it's up to
the Turtles to stop the conflict before it escalates into all-out
war! Collects issues #76–80.
