ok im going to start with gaunlets. you could get a electronic tinkering table and get or make a plain proto type gauntlet and tinker with it until you get a cool power like electricity gravity, ai programing ect. the proto gauntlet would have to be pluged into a power block or the tinker table and upgrade your gauntlet to advanced versions like a heavy that would make you were a power block on your back and make you slower but your gauntlet would go longer charged and have stronger hits. a light one that would fire faster and unchange your spead, but would do less damage and run out faster, ect. and you could upgrade them to improve stats or them
