Like her cousin, Jennifer possesses great strength, durability, endurance and a healing factor. Unlike her cousin, she almost always retains her full intelligence and personality as She-Hulk. She is also able to switch from She-Hulk to Jennifer Walters, but does not always have control of her transformation. In the past, Jennifer's inability to switch forms was due to a psychological block. Jennifer has learned a Ovid body-switching technique, but rarely uses it. The Scarlet Witch also put an enchantment on She-Hulk so that anyone who wishes to harm She-Hulk will not be able to perceive her while she's in the form of Jen Walters. While useful it later backfired and was removed by Doctor Strange.
