Compared to the Mai from Dragon Ball, Future Mai is a young-looking and tall woman with fair skin with black hair along with bangs. Unlike Mai's older appearence, She has big black eyes rather than her blue-eyes (probably she has contact lenses) and she doesn't have make-up on. She wore the same long, blue jacket but the star logo on each part of the jacket is yellow instead of grey and her pants is yellow than beige.
Like her main timeline counterpart , Future Mai's youthful appearance is the result of youth granting wish Future Pilaf made. In a special chapter of Dragon Ball Super manga describing this event, shows that before her transformation Future Mai was a middle-aged woman, somewhat similar to how Present Mai appeared in the beginning of Dragon Ball GT.
In this timeline, Future Mai is much more kind and selfless than her Present counterpart. Mai is very caring towards animals and others, by giving food to Future Scratch and insisted that Trunks eat the can of food given to him. Despite their past history, Mai respects Future Bulma and her present counterpart, as well as Vegeta and Goku (the former two for their knowledge and the latter two for their fighting skills).
She has strong leadership skills, being widely considered as the troop's morale, as she never gives up even in the face of despair. Mai cares deeply for the people she rescues and after Zamasu had exterminated the rest of humanity, Mai angrily shoots at the bodiless entity continuously until running out of ammo. When Whis tells her and Trunks that he is going to alter the future, Mai becomes happy at the thought of seeing her friends again.
Mai has a good relationship with Trunks (even putting him over herself), believing him to be the final hope for their future and has saved his life on several occasions. After reuniting with him, Mai teases the weeping Trunks by saying that men shouldn't show their tears. Whenever a topic of her relationship was brought up, she denies it while at the same time blushing. Another instance was when Bulma jokes about her future self becoming a grandma, much to their embarrassment.
Dragon Ball Super
Future Mai's life was the exact same as her present counterpart's until Age 767 when the world was put into the ruin from the Androids. Just like in the main timeline, she and the rest of the Pilaf Gang were turned into toddlers by Pilaf's wish for youth from Shenron. However, in this timeline their wish turned into the last one Shenron has ever granted, as mere few minutes later Future Piccolo died and the Dragon Balls permanently turned into stone. The fate of Pilaf and Shu remains unknown, but Mai survives the Androids' rampage and regrows into a young woman.
Future Trunks Saga
Future Mai appears in the Future Trunks edition, and saves Future Trunks from Goku Black by throwing a flash grenade at him. The two retreated and hid themselves, Trunks thanks Mai and she questions that he is the his world's final hope and if he died, who would save them to which Trunks apologizes.
