Marbo finally talks. His first words are "I AM THE LAW". He then goes on to fight Calgar in a boxing match, only to lose on points. He beats him in a rematch, but is defeated by Vulkan. After training with the Ultramarines, he fights Vulkan and reclaims the title. Calgar fights Abaddon and is killed. Marbo goes to the Eye of Terror to fight him, wins both the match, and the approval of the watching daemons, and gives a passionate speech about how they learned to love him, so maybe everyone can learn to love each other, and the wars can stop. The daemons agree, and pour out of the Eye preaching how Humans aren't that bad. The Inquisition finds out and tries to kill Marbo, only for him to defect and join a Tau colony as a snake catcher. When a group of Daemon Doctors try to help the local Tau rebels, they are captured and the rebels slaughtered. Marbo leads a small unit of troops made up of Shrike, Harker, Stracken, Lukas the Trickster and Telion to reclaim the Doctors. He makes friends with Telion who tells him to call him School Boy, as he schools all the young scouts. They manage to reclaim the Daemon Doctors, and flee, only to be captured by the Tau forces. Marbo and Telion sneak up behind the capturing troops and use a Heavy Bolter to cause ridiculous amounts of damage to the troops, who are massacred. When speaking to one of the Doctors, Marbo learns that the Imperium has changed, and goes back, with a green bag over one shoulder.
He is captured by the Inquisition who freeze him for his crimes. 20 years later, after releasing Ragnar Blackmane from cryo imprisonment, Blackmane goes on a rampage and destroys the various planets of the now peaceful Imperium. The Imperium is forced to release Marbo, on the suggestion of the Living Saint, who refers to his old nickname of "Demolition Charge Man". He is used to kill Blackmane, yet simultaneously making the Imperium a better place for everyone. He falls in love with the Saint, and the two of them live happily ever after.
Now to see the expendables and fit more into the chronicle of Sly Marbo...
