Take control of an NSA agent with access to the most powerful hacking tools, hack everyone’s phone, install a program that randomly have a popup at random intervals, the popup message says “I’m watching you”. This also tries to spread itself to any other phone it can connect to. Pure chaos 😈
Pretty sure I can do this in a minute, depending on how good the NSA tools are.
Have Trump take off his diaper on TV and say “my smol wee wee has poo poo on it, me sad”
Give it like a month and you won’t have to waste your one ability use on this.
