Lily and Riley’s future son Maxwell Edison “Max” McCallistar. Max is about 13 as pictured here. He is an active, fit boy that likes to have fun above anything else. He seems to have a bit of his aunt Penelope in him! He’s a thrill seeker and a daredevil, which is likely to give his poor mother a heart attack if she knew about half the crazy stuff he does! This boy has a need for speed, and is a total adrenaline junkie! Despite all that, he is a sweet, well mannered boy that would give the shirt off his back to anyone! Yes, that is a hoverboard like the ones in Back to the Future II and his full name is a Beatles reference!
