Zim Hates Beans

This is an AU where Zim is a human and his last name is Robinson. About Zim: 11 years old, independent, egotistical, wants to rule the world one day, has a rare skin condition where his skin is tinted green and when he touches water it feels like his skin is burning, has autism and trouble hearing sometimes, rarely eats due to food sensitivity, builds machines in the basement that his parents don't know about. Also in this AU, the roboparents Zim uses are his actual parents, they're very goofy and love him. Story: Zim and his parents were eating dinner. Zim's mom made chicken, mashed potatoes, and BEANS (we all love that meme). Zim never really liked beans but he ate them anyway, and that's when he started to have an allergic reaction.
