Young Avengers #1

In Los Angeles, a quick moving superhero, Speed, interrupts news coverage of a fire in an abandoned mansion. The fire department has the blaze under control, but Speed is adamant that he needs to help. The reporter on scene introduces the 'hero' as Speed a notorious and flamboyant member of many small super-powered vigilante groups.

When he overhears that one of the fire marshals is trapped on a balcony, Speed rushes into the flames to save him. Unfortunately, in his haste, he forgets about back draft, and opening the door to the balcony causes a massive explosion of fire that brings the whole blaze to an uncontrollable peak. The back draft causes an explosion that sends Speed flying back onto the pavement, and a fireball up into the air. Most of the crowd starts yelling at Speed. Fire crew members yell at him to leave.

The newscast continues, and discussion ensues regarding the recent up-cropping of super-powered teens. From his hideout in a Fisk Towers penthouse, former Spider-Clan member Matt Murdock watches the news coverage and worries about the apparent pattern in the disappearances of several of these teen heroes. Thinking back on his own tenure as Daredevil, he wonders what his mentor Spider-Man was thinking when he brought a teen into crime fighting.

Suddenly, Matt senses someone behind him, and turns to find a man in dark glasses and a team of gunmen waiting. Matt, as Daredevil, has been expecting them to come for him. The man suggests that he has been authorized to give Matt clemency if he agrees to use his talents for his employers. In response, Matt warns that he has rigged the building to explode, and when they realize he's not bluffing, everyone struggles to escape. Leaping off his balcony, Daredevil grapples onto the building across from his and swings to safety.

In Malibu, Pre-law student Jennifer Walters drives a stolen car down the Pacific Coast highway. A police officer pulls her over, and she turns on the waterworks, pretending that she's just joyriding in her mother's car. Suddenly, the policeman grips her by the throat and lifts her to her feet. Fortunately, Daredevil appears, knocking the cop unconscious. 

Daredevil says he knows that she is the person the media are calling She-Hulk, and informs her that an organization is after superhuman teens like her. Jennifer denies having any powers, but when a chopper shows up and begins opening fire with machine guns, she turns green and shows her hulk side. 

Angrily, Jennifer transforms into She-Hulk, leaping onto the chopper, and smashing it to pieces until it crashes into the ocean. As she crawls back up, she reminds Daredevil that she doesn't want to be called She-Hulk, and he renews his efforts to get her to join him. 

Elsewhere, the man in glasses demands that Doctor Childs release their experiment: Sentry.
