Edison

Edison-Alpha, or just Edison, is the obnoxious, sarcastic and sadistic AI that inhabits Robin's blaster. Despite being surprisingly knowledgeable, he doesn't trust anyone without a reason to do so, and never shares what he knows, in case it can be used against him. The only person he bothers paying attention to is Kokiri, because she is unbelievably gifted with technology, and could take him apart in a few seconds flat. So, mainly out of fear. And because Kokiri made him.
