Jack and the Automaton Error

Jack is a 11 year old kid. After being kidnapped, Jack gets radiation immunity allowing him to use nuclear powered armor to protect the city. On the way he meets a superhero named golden goddess and an alien with a coffee bot. After hanging out with his new friends, LEXI, an AI that helps the city, for some reason turns evil and wants to take over the world. Will Jack and his friends save the day, or will everything collapse and be destroyed? Will they become heros, or will vengeance, horror, and torture arise?
