A-diot is an Artificial Intelligence that is mostly an idiot. If you ask him something, he won't understand you and will do something instead. Example: You asked him to install an anti-virus, and he installed more viruses instead.
He doesn't get along with other AI really well. If he meets another AI, he will just yell bad words at them.
He can also hack people and cause chaos. If you see him on your PC, destroy PC. TV? Destroy it. Phone? Also destroy it. If he invades any of your devices, destroy them (even if they're expensive), because, if you don't he will do bad things like leaking your browser history, install viruses or corrupt your apps. You're probably like "what about my gaming consoles?" Well he doesn't hack Gaming Consoles because he doesn't know how to do it yet.
Don't be fooled, because he has some tricks up his sleeve. He is also trying to break free into the real world.
