Electronic manipulation.
By converting the nen into a signal this Hatsus allow to manipulate wathever receive the signal. While it does allow to animate electronic thing, the puppet is rather easy to beat, but then the puppet can send a signal to other electronic device so that they may aglomerate and become stronger. The typical strategy would be to call the target to infect the phone. Depending on the strenght of the target the phone manipulated could send all it's energy to the brain to kill the target (this only only work for weak people). the user must prepare the field so that there is a maximum of electronic thing to manipulate to beat stronger foes. the strenght of this hatsu is the long range allowing for battle that may last for day as it allow to watch the target at all time, it allow the user to set up trap and finding way to bring more electronic to the target. To beat the user, the target should find his hidding point and then hurry up there to beat him personally. This is the first time i'm making an hatsu so if you could give me advice about restriction or way make this ability more balanced or better.
