She-Hulk

Powers
Gamma Radiation Physiology:

Physical Transformation: As a result of a blood transfusion from her cousin Bruce Banner, AKA the Hulk, Jennifer Walters is able to alter her physical form into a female version of the Hulk. As She-Hulk, Walters' skin, hair, and eyes all turn green. Her frame also gains another 9 inches in height and 560 lbs of muscle and bone tissue. Unlike her cousin, the Hulk, much of Jennifer's gained muscle and bone mass is condensed and several times as dense as that of a human. As a result, though she is noticeably much larger than she is in her normal form, she looks much lighter than she actually is. Also unlike the Hulk, or rather certain Hulk incarnations, Jennifer retains her full intelligence and personality in her She-Hulk form. Most of the time, Walters is able to control her transformation, enabling her to change back and forth at will. This is because she did not suffer as much psychological trauma as a child as her cousin did. And while it augments her abilities, she retains greater control than her cousin.

Superhuman Strength: As She-Hulk, she is proportionally stronger than her Jennifer Walters form. This means that any extra strength gains as Jennifer Walters through intense physical training will be amplified, making her She-Hulk form that much stronger. As a result of her intense training, She-Hulk's calm strength currently surpasses the base strength levels of the Gray, Savage, and Professor incarnations of the Hulk, at least while they're in a calm emotional state. Originally She-Hulk was listed as only "class 50" (this is only a comparison scale regarding which character is stronger than who, and should not be taken literally. For example: Thor was listed as "class 95" at the time, and Hercules at exactly 100).[60] Right after she came back from the first Secret Wars as Thing's replacement in the Fantastic Four she began to workout with Thing's weights and got her strength up to at least class 75 [61] but through her career she continued to lift even greater weights, and the uppermost limit of her potential remains unknown. After prolonged weight-lifting training, she was able to easily defeat the Champion of the Universe, effortlessly supported the Thing's maximum weight with a single arm, threw an arm-wrestling competition with Hercules to spare his feelings, and effortlessly manhandled a Thanos clone. She is currently listed as above "class 100" (Listed equal or stronger than Thor and Hercules)[62]. It has been stated and shown that like her cousin, her strength increases with her emotions, such as fear and rage, though not to the same level that her cousin can achieve.[63]Currently, her strength is so great to the point she matched the Immortal Hulk who took down Thor in one blow.[64] She-Hulk's leg muscles are sufficiently strong enabling her to leap capacity heights of at least 600 feet and a surface distance of at least 1,000 feet.[65]

Superhuman Speed: Due, at least partially, to the great muscular strength and development of her leg muscles, she is capable of running and moving at speeds that are beyond the natural physical limits of the finest human athlete.

Superhuman Agility: She-Hulk's agility, balance, and bodily coordination are all enhanced to levels that are beyond the natural physical limits of even the finest human athlete.

Superhuman Reflexes: She-Hulk's reflexes are similarly enhanced and are supperior to those of the finest human athlete.

Superhuman Stamina: She-Hulk's highly advanced musculature produces considerably less fatigue toxins during physical activity than the musculature of an ordinary human. She can exert herself at peak capacity for about 48 hours before fatigue begins to impair her performance.

Superhuman Durability: In addition to her strength, She-Hulk possesses a high degree of resistance to injury. Her skin is capable of withstanding tremendous pressures, temperatures from -190 F to 3,000 F, falls from great heights, field-artillery canon shells, and powerful energy blasts without sustaining any injury.[65]

Regenerative Healing Factor: Despite her body's extremely high resistance to injury, it is possible to injure her. However, she is capable of rapidly regenerating injuries that result in great tissue damage and blood loss within a matter of minutes. However, she is not capable of regenerating missing limbs or organs. She-Hulk's highly efficient metabolism renders her immune to all drugs and toxins as well as total immunity to all known Earthly diseases. Reactive Adaptation: There were several events in the past where the Hulk not only faced extended periods of time in oxygen-deprived outer space without suffocating, but he also frequently spoke in these inhospitable habitats. It was theorized by Nick Fury that the Hulk could adapt to the environment of space as an inherent property of his mutation. He based this thesis on accumulated data about the Hulk.[442] For example, Hulk can harmonize his biological structure with the depths of the ocean.[443] Fury's hypothesis has been confirmed, since it was stated that the Hulk can adapt to any environment, even airless space.[444] Therefore this evidences that the Hulk could adapt to a wide diversity of hostile habitats. It is plausible that this ability is enhanced and amplified by the Hulk's rage. Accordingly, it has also been stated that the Hulk does not always need to breathe.[261]
 * Disease Immunity: The Hulk is completely invulnerable to all known Earth-based diseases and viruses, including AIDS.[172][430] He can operate under intense conditions for prolonged periods of time due to his body not developing fatigue toxins quickly.
 * Decelerated Aging: For all intents and purposes the Hulk lives indefinitely. Because of an enhanced regenerative healing factor, derived from the properties of gamma energy that empowers him, Hulk has a prolonged lifespan.
 * Underwater Breathing: The Hulk has been on the ocean floor a number of times. The Hulk is able to breathe due to his body developing a gland which creates an oxygenated perfluorocarbon emulsion which fills his lungs and equalizes the pressure.[123][134] He is therefore able to breathe fluid and avoid decompression and nitrogen narcosis.

Gamma Radiation/Energy Manipulation and Emission: Not usually a power associated with the Hulk, but there is enough evidence that Hulk possesses at least a limited ability to manipulate forms of energy, particularly gamma radiation. The Hulk's body works like a "gamma battery" by constantly creating and radiating gamma energy.[87]

Abilities
Expert Combatant: The She-Hulk is a formidable hand-to-hand combatant, having been trained by Captain America and Gamora. Even in her Jennifer Walters form, she possesses sufficient skill in the martial arts to dispatch several would-be muggers much larger than she is. She is also highly trained in the use of weapons and battle tactics and strategies.

Skilled Pilot: Jennifer Walters is a good pilot, as has been shown in multiple issues of Avengers and Fantastic Four.

Expert Attorney: Extremely intelligent, the She-Hulk is a skilled and experienced lawyer. She has won many cases proving various civilians, costumed heroes, and even villains innocent.

Law Degree: Jennifer attended UCLA School of Law, where she was a member of the Order of the Coif, a national merit society for top legal scholars. Walters has also attended Harvard Law School; though details are not provided, it is probable that she earned a master of laws (LL.M.) degree at Harvard[66] to complement her juris doctor (J.D.) degree from UCLA.[29] She has shown great versatility in her legal practice, representing criminal defendants, corporations, and even domestic violence victims.[67][52]

Weaknesses
Radiation: Exposure to certain wavelengths of radiation only at very high doses can sometimes temporarily inhibit or override her ability to transform between forms. This is usually only a weakness if she is exposed during her original/Jennifer form.
