Weapon: A dual set of gloves which when used extend into super sharp claws.
Ability: Further enhanced physical capabilities(strength, speed, durability, reflexes, stamina, regen, etc) and replicate the capabilities of creatures in the animal kingdom(scaled up to human, and think venom, fangs, wings, etc).
Sub-Abilities: (split this into categories based on how soon they would probably be unlocked)
Earliest:
-Further enhanced physical capabilities
-Retaining characteristics when not active
-Use more characteristics at once
-Light Armor extending over body(dermal and subdermal armor)
-Danger sense(not precognitive)
Later:
-Shapeshifting(able to use animal characteristics without having them be noticeable)
-Much more enhanced physical abilities
-Mixing and matching animal characteristics to enhance/create new ones
-Moderate armor covering body
-Danger sense(mildly precognitive)
Much later:
-Immensely enhanced physical abilities that begin to slowly grow with age
-Able to utilize mythical creature abilities(Phoenix healing, dragon breath, dragon scales, etc)
-Able to develop resistances to other things over time(though never immune)
-Biological immortality
-Danger Sense(moderately precognitive)
-Able to create mutations in other creatures
Far future:(because no limits given)
-Able to develop immunities and abilities from the things I became immune to or from things I eat(even more so when I’m berserk state)
-Faster strength growth
-Danger sense(very precognitive and continues getting better)
-Able to create creatures wholesale from the ground up and control the created creatures
Burst Ability: Enter into an animalistic berserker rage state where physical capabilities are boosted massively exponentially from wherever they currently are and adopted characteristics are boosted equally in sharpness, venom potency, armor toughness, etc. Lose most ability for higher thought at first but eventually be able to control it more(think the hulk). Develop resistances/immunities to damage taken previously in this state even if yet to unlock that ability outside of this state though these are only present while in this state. Lasts until threat is beaten or escaped. It will combat the threat I triggered it for until defeated or it sees no chance and will flee. Before deactivation it requires a massive amount of food mainly meat and afterwards will find a safe space and sleep for upwards of a week(decreases with many many repeated uses)
