This is a front paw gauntlet used in yinrih powered armor, with the palm facing up. The purple pads on the digits and palm are force projectors (Commonthroat name TBD). They use Science™ to exert force at a distance. They can also generate a negative force normal to the surface they're pressed against to allow the wearer to climb smooth walls and ceilings.
By thrusting the palm forward, a force extends outward, acting as a long-distance punch. It may be able to be used like the Mage Hand spell from D&D, allowing object manipulation over short distances.
One technique is to cup the two front paws together before thrusting the forelimbs forward. This overloads the two projectors, causing them to generate a large ball of concussive force that is launched forward at high velocity. This is frowned upon because it burns out the projectors very quickly. This little trick is inspired by the Kamehameha from DBZ, as in there are actual yinrih weeaboos who thought the move looked cool and wanted to see if they could pull it off with force projectors. Sometimes when in zero gravity they'll even use all four paws to do it. The other reason it's frowned upon is that it has some serious kickback. Since the person performing the move is reared up on their hind feet, it almost always results in them losing their balance or even flying across the room.
The flexible material that the gauntlet is made of is called Pseudosinew (Commonthroat name also TBD). It's a fine mesh of artificial musculature. It can enhance dexterity and strength passively to some degree. When powered it can do that even better, as well as block small non-relativistic projectiles by reflexively tensing up when struck, sort of like a “non Neutonian solid”.
