"Take me to the woman's wing, Donna," Gamecock said, throwing his arms around his love-****'s shoulders. She picked him up with one arm, and dashed off into Iron Heights prison. He liked having Wonder Girl pick him up and carry him. He felt... safe. And he could grope her breasts while she carried him. Win-win as far as he was concerned. She dashed off with the speed of Mercury. Iron Heights was a big prison; it and Belle Reeve held almost all superhuman prisoners in the United States, especially after the Slab had been destroyed by Brother Blood.

That didn't mean that the women's section of the prison was expansive though. A number of the more well-known supervillanesses were at Arkham Aslyum; your Harleys Quinn and Poisons Ivy.

Wonder Girl came to a complete stop, and Gamecock nearly felt his lunch come up and out of him. But he took a second to breath, and it kept down. It was hard to dash around at super-speed if you didn't have super-speed, Rupert decided. Oh well, he was going to need Wonder Girl's speed if the Scarlet Speedster of Keystone City decided to investigate whatever alarms they had tripped in Iron Heights.

He was on a timer, he realized. If the Flash came, he wasn't sure if Donna would able to take him in a fight. He only had time to free one prisoner and take her along. There were three prisoners right in front of him, and they all looked like they'd be fun.

Above the first prisoner's cell, a sign read "Plastique - Sans Souci, Bette." He had remembered this one. She wasn't always a supervillain! She had been a member of the Justice League, he was pretty sure. He was also pretty sure that she had been involved with one of the other heroes. Blue Beetle or Captain Atom, he couldn't remember which.

On the second prisoner's cell, there was a sign that read "Giganta - Zuel, Doris." Gamecock vaguely knew of this one. She had been a member of the Legion of Doom, he was pretty sure of that. And she was seen in Ivy Town, Rhode Island before being arrested. If he really plumbed the depths of the superhero tabloid that he read, he was pretty sure that she had dated the Atom. What was it about female supervillains that enticed superheroes so?

The third cell had a sign. "Silver Swan - Kapatelis, Vanessa". Rupert thought he was a fanboy. He knew that there was more than one Hawk and Dove. He had clipped photos of Wonder Woman out of the newspaper. He was pretty sure he had never heard of this one. But she seemed younger than the other two. Closer to his and Donna's age. And she was just as pretty.

He only had time for one prisoner, he was pretty sure.
