A book that I'm currently writing called Surge, my protagonist, Joseph Norton is an "Ascended", a human that is able to draw upon an energy source called the Nexus (à la the Force) to enhance his physical abilities as a byproduct by having his soul bound to an incredibly powerful and ancient weapon referred to as a Divine Tool. As an Ascended, Joseph can tap into the Nexus to perform superhuman and physics-defying feats such as moving faster than the human eye can track, throwing multi-ton cars with some degree of difficulty and being able to take a rocket-propelled grenade to the chest at point blank (which nearly kills him). Each Ascended has 3 - 4 primary abilities that embody their most dominant personality traits.
Joesph's powers include:
Precognition (representing his cautiousness and pragmatism) that only works if he's aware of what's going on around him and his senses are unimpaired.
A healing factor (representing his willpower) that automatically repairs broken bones, internal bleeding, and damaged organs and allows his immune system to resist toxins. But, Joesph can't regenerate limbs, survive decapitation or reform his body from a single cell.
Replicating weapons from his memories (representing his analytic nature) such as swords, maces, lances, halberds and axes but due to a bad case of Anterograde amnesia and the fact that they have hundreds of components, he can't recreate guns or grenades (think Tracing from Fate/stay night). Joseph later learns how to take on the powers of other Ascended using this ability, although his amnesia only allows him to create flawed imitations limited by his fragmented memories and shut off his original powers when using a duplicated power.
Electrokinesis (representing his inner emotional turmoil) that allows him to shoot bolts of energy from his fingers, fire beams of electricity from his palms, hurl lightning bolts like spears and call down lightning strikes. This ability has its limits as Joesph can't absorb electricity from other sources and can still be harmed by electric attacks.
Joseph's Electrokinesis also allows him to channel the Nexus through his hands and feet to transform his fingers and toes into electrified claws, which complement his kickboxing and parkour skills by allowing him to rapidly scale vertical surfaces such as brick, concrete or glass walls. I've been trying to figure out what sort of claws would be practical for such purposes. I originally settled on hook-like talons similar to those of eagles (which would've tied into the eagle motif) attached to his character), but when I did research on eagles, I learnt that their claws evolved primarily to restrain large struggling prey, and were poorly suited for combat or climbing.
Are there such claws that allow for both close quarters combat (CQC) and fast climbing?
NOTE: Keep in mind that Surge's setting is modern day
