In this 7th Volume, Plutonian picks up where he left off in an insane asylum inside a sun. his companion is in his dreams, and also reality, and they plan an escape. Along the way they run into some other interesting inmates with interesting powers.
Meanwhile, Qubit and Mobius track Tony down to the asylum, setting up a confrontation.
This volume is fantastic for showing us Tony travelling through the levels of the asylum alongside his companion(s), and eventually the one who first pushed him in the direction of an escape reveals his true identity and what he's tried to do for Tony and what Tony has done for him...it is the events that follow that revelation which finally show Plutonian to be IRREDEEMABLE.
The events and showdowns leave us at such a point that perhaps Plutonian isn't as defeated as we once thought...
Meanwhile on Earth, Survivor is the only original Paradigm membee left, having recruited former villains and criminals as a rehabilitation project. However, he seems to be heading even closer to some sort of breakdown himself.
Qubit is with Mobius, as we know, and Kaidan is being held by Mobius as prisoner, guarded by the remains/corpse of Scylla, Survivor's twin, thought dead previously.
Setting things up for a potential collision between various forces, and that's to say nothing of Max Damage (of Incorruptible) Tony's other biggest former enemy, now a hero in the remains of Earth.
As with Incorruptible, these series' should be read from the start both, and try reading both, though I suppose you could read much of one without the other, they are most effective when paired together.
