Transformation: After acquiring the powers of Mako, she could transform herself into an amphibious, anthropomorphic shark.
Superhuman Strength: Like Mako, she is strong enough to punch through concrete and throw trucks at opponents.
Limited Regeneration: Allison’s teeth can easily bite through very strong substances. If they break, they can in fact grow back at a fast rate.
Superhuman Endurance: Her skin provides relatively strong body armor against physical injury, and can barely be penetrated by metal blades.
Enhanced Vision: Allison can also presumably see clearly underwater.
Amphibious: Like Mako, Allison also possesses amphibious traits, such as the ability to deftly swim underwater, as well as breath under water.
Enhanced Senses: She has a great sense of smell allowing him to track down opponents (i.e. lunch).
Abilities
Throwing: Like her aunt, Allison has an uncanny, almost preternatural accuracy with various forms of throwing darts, and is able to throw consistently on-target even while performing complicated gymnastic, acrobatic or martial arts maneuvers.
Gadgetry: She carries with her a number of "trick" darts in addition to the normal ones that are merely razor sharp. There are a number of different types of trick darts: some are explosive, some incendiary, and some release toxic or irritating gas, such as tear gas.
Martial Arts: Allison is in excellent physical condition and is a skilled martial artist.
