Thor

Thor's powers and abilities

As Thor, Jane wielded Mjolnir, and like those before her, she had been bestowed with power equal to that once possessed by Odinson; whatever powers she may or may not possess outside of those provided by Mjolnir are unknown:

Superhuman Strength

Thor possesses class 100 strength and is easily capable of lifting 100 tons.

Superhuman Speed

Superhuman Durability

While in the form of an Asgardian Goddess, Thor possesses virtual invulnerability and immunity to all known Earthly diseases and infections.

Superhuman Stamina

Superhuman Senses

Self-Sustenance: She is capable of surviving in the vacuum of space unaided.

Healing Factor

Like all Asgardians, Thor has a highly advanced metabolism that enables her to recover with superhuman speed and efficiency. While the extent of ability to heal is unknown, it doesn't appear to be able to heal her cancer. Instead, the cancer appears to be suppressed and isn't lethal to Thor as long as Thor retains her Asgardian form.

Longevity

Energy Manipulation

Lightning/Electrokinesis

Thor usually uses Mjolnir to channel her storm abilities, but she is capable of discharging lightning bolts without it; notably using to destroy a frost giant's head from the inside.

Abilities

Nursing Skills

Initially Jane was a competent and effective nurse.

Medical Training

After years as a nurse, Jane completed her medical training and obtained a Medical degree

Thor's weaknesses

Separation from Mjolnir

Similar to the previous enchantments involving Don Blake and Eric Masterson, Thor's powers were derived from Mjolnir; separation from it for more than a minute resulted in her powers fading quickly.

Breast Cancer

Jane was diagnosed with breast cancer. She later accepted Thor's invitation to represent Midgard in the Congress of Worlds on Asgardia while she underwent therapy, but refused magical treatments. While empowered Mjolnir she was at perfect health. But when she returned to normal the chemotherapy was removed from her system, preventing the treatment from working and endangering her life. After Mjolnir's destruction, Jane finally got the treatment she desperately needed and is now in complete remission
