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.
Overall, Hulk is usually stronger than She-Hulk in the comics. Hulk's rage-fueled power can reach extreme levels that She-Hulk doesn't often match. However, She-Hulk has her own unique strengths and abilities that make her a formidable character in her own right.
In most comic storylines, Hulk is stronger than She-Hulk. But it's not always black and white. Different writers and story arcs can present variations in their relative strengths.
It depends on the situation. In terms of raw physical strength, the Hulk is incredibly powerful. He can smash through mountains with ease. But Naruto has his own set of skills. His ninjutsu, like the Rasengan, can cause a great deal of damage. Also, Naruto has the power of the Nine - Tails, which gives him a huge boost in chakra. If they were to fight in an open field, the Hulk might have the upper hand in a direct physical clash. But if Naruto can use his ninja skills to his advantage, like creating diversions with clones and hitting the Hulk from unexpected angles, he could potentially win.
One reason could be a misunderstanding. Maybe some villain has tricked Hulk into believing Spiderman is a threat. For example, the villain might have faked some evidence to make it seem like Spiderman was planning something bad against Hulk or his friends.
Well, in some fanfictions, Hulk might physically stand in front of Spiderman to shield him from attacks. For example, if there are powerful villains shooting energy blasts at Spiderman, Hulk's huge body can act as a barrier.
Spiderman's agility and web - slinging abilities could be combined with She - Hulk's super strength. For example, Spiderman could use his webs to create a net and She - Hulk could throw it with her great strength at enemies. Or Spiderman could swing She - Hulk around to gain more momentum for her attacks.
It could be a new super - villain created specifically for the fanfic. Maybe a scientist who has developed a formula that gives him the ability to manipulate energy and he wants to use it to take over the city. His powers would pose a threat to both Spider - Man and She - Hulk.
