At the city dump, the grown Gangreen Gang were gathering together for a game of poker. Never the biggest fish in the pond that was Townsville's criminal underworld, nowadays, they were still small-time. Though still with no interest in going straight.

It was the welcome home party for leader Ace Copular, having been just released from prison, his first major bid to happen due to being tried as an adult. Which was quite different from his stints in Juvie, where he could easily become one of the head sharks of the joint with his skill at manipulation. But, in prison, he was just one mook out of many serving their time. It felt great to be on the outside again, with his pals again.

His right-hand and best friend Sanford 'Snake' Ingleberry was sitting next to him. A thin snake-like man who often sounded like he was hissing, Snake had been running the gang while Ace was imprisoned and preferred to keep a low profile-especially beneath the notice of the Powerpuffs, fearing yet another beatdown from the superheroines.

Snake had been the one to have picked Ace up from his release from prison. A happy reunion turned sour when Ace complained to Snake about him and the gang not pulling any big scores while he was on the inside. Snake tried to protest, but that only earned him a punch to the nose. Snake rubbed his aching nose, sighing. Same old, same old.

Next to Snake was the mutant known only as Grubber, the most hideous of the bunch. His eyes bursting out of their sockets caused this fiend to be feared on-sight by the law-abiding citizens in Townsville along with his unpredictable violence. Grubber usually spoke only by blowing raspberries (that his fellow gangbangers had learned to understand), but, beneath the savage exterior, lied a cunning criminal mind, able to imitate peoples' voices and change his appearance (though the exertion it causes him means that he can only keep up his façade for only a few minutes).

As usual, Grubber was winning the game, but Ace had a feeling that tonight would be the night his luck would change.

Then there was William 'Big Billy' Williams, the gang's gigantic cyclops. Billy was dimwitted, but with a childlike innocence to him. Unlike his friends, Billy actually liked the Powerpuffs (them having saved his life before), but still follows Ace's orders to the letter. Sometimes his stupidity could groan on the rest of the gang, but they still kept him around due to his great strength.

And finally, there was the midget Arturo de la Guerra. The youngest member, Arturo had been in and out of juvies for years, but now that Ace was out, it was their chance to finally get into the big time.

But their poker game came to a sudden halt when they spotted three beams of light (one red, one blue, and one green) heading straight for them.

Ace groaned. He had just gotten out, and the girls pick now to come after him?!

Within seconds, all five men were picked up and were transported to the park.

Shaken by the trip, the Gangreen Gang looked up and were shocked (and horrified) to discover standing over them, instead of the Powerpuffs, were the Rowdyruffs.

The Gangreens began pleading, exclaiming that they had done nothing to them, had always respected them, but Brick only told them to shut up.

Brick turned around to the three boys (the Gangreens were struck by how much the kids resembled the Rowdyruffs when they were younger) and announced that 'these bums' would be their first training dummies, causing the Gangreens to cringe in fear for the coming beatdown.

Charlie was willing to obey, but Cole spoke up, asking why they should attack these men they did not know (giving Boomer confusion on what to say). Cam repeated the question, but in a more bored tone.

Butch stepped towards them, growling, and gave them the reason why: he was going to give them the thrashing of a lifetime if they didn't. The two boys stepped back fearfully before acquiescing.

The next thing Ace & pals knew, they were being punched rapidly by the three kids until they lost consciousness.

Standing over their five victims, the three boys contemplated what they had just done. Charlie yearned for a fight, but there was no satisfaction in beating up people so helpless (hoping that these Powerpuffs would put up more of a fight), Cole was horrified, terrified by the blood coming from the men, and Cam was ambivalent, not caring about the men, but glad that he had avoided a beating from his 'dad'.

Brick complimented the boys before leaving with them and his brothers.

The Gangreens came to quickly (the beatings the Powerpuffs had given them over the years giving them a high tolerance from pain). They laid there on the grass, groaning in pain.

Ace couldn't believe it. He had just gotten out of the joint and now he had another generation of these monsters to deal with.
