Max is one of the children of Andre's and Syfin's family, he's the youngest one of the family, his bag can turn to a music box in reference of Sonic Undergrounds (for some reason), he carries around an orange chaos emerald that he is meant to both the 2nd protector of it and be a user of it, absorbing the orange chaos emeralds gives him some chaos abilites and one that is a weaker version of Chaos Control (that I made up) called "Chaos Time", which stops time for 5 seconds depending on what form he is in. Max is also a child that knows parkour, it's unknown why he does it though.

Vore related part; Max is most likely 100% prey, he is mostly willing prey, so he would LOVE to be eaten (whole) by preds, though sometimes he just doesn't want to be eaten though, so he would avoid you, which he is pretty good at.
He is scared of being digested though, likely he never got digested, he was only told how it was like.
