Grizzly joins the Thunderbolts team.

He has information about the whereabouts of the Agents of Atlas, who Norm sees as competition in his quest for world domination.
From there, these issues are basically one long, kinda entertaining fight between the Thunderbolts and the Agents of Atlas.

Members of both teams get critically injured by Scourge, aka Nuke.

On the AoA side, Nuke–under the influence of Venus’ hallucination-inducing siren song, cuts Uranian open and nearly kills him.
The fight then ends in a draw, and Nuke does his second piece of damage. As the T-Bolts leave the site of the fight, their boss Norman Osborn contacts them by hologram. Scourge (aka Nuke), whose mind is still addled from the effects of Venus’ siren song…

…Now sees Osborn as his enemy and shoots at the hologram.

The bullet passes through the hologram and kills Headsman.
These issues are just okay. The muddied art doesn’t do the thin story any favors.
