She - Hulk has a couple of ways. Firstly, her enhanced durability means she could potentially shield others from the blast of a bomb if she positions herself correctly. Then, she could track down the villain by following the evidence left behind by the bombs. Once she finds the villain, she can use her strength to overpower them. If the bombs are controlled remotely, she could also use her intelligence to figure out the control frequency and jam it, preventing the villain from detonating the bombs. And of course, she can use her green rage to intimidate the villain into surrendering before they even get a chance to set off more bombs.
Captain America would be a great addition. His leadership and moral compass could guide Hulk and She - Hulk when they face difficult decisions. And his combat skills could come in handy during battles.
Sure, She-Hulk is related to Hulk. Jennifer Walters, aka She-Hulk, got her powers because of a blood transfusion from her cousin Bruce Banner, who is Hulk. This connection is a key part of their storylines in the comics.
In many comic versions, She-Hulk gets her powers after being exposed to gamma radiation, similar to the Hulk. But the details and circumstances can differ in different story arcs. Sometimes it's due to a scientific experiment gone wrong, or a deliberate attempt to gain powers.
She-Hulk became She-Hulk because of a unique set of circumstances. Bruce Banner's blood, with its gamma radiation, entered her system during a medical emergency, and that's what caused her to turn into She-Hulk. This event changed her life forever.
Comics usually depict Hulk as stronger than She-Hulk. Hulk's strength levels are often at a much higher magnitude, but it doesn't mean She-Hulk is weak by any means. She has her moments and skills that contribute to her being a significant character in the comic universe.
