Michael Belpois is the father of Jeremie. Unlike his son, he does not have blonde hair (it's his wife that has blonde hair). He is proud of his son's intelligence and is a very loving dad. He does not know about Lyoko, He is aware of Jeremie's feelings for Aelita and has even commented that he thinks she is a very nice girl. He even let Jeremie go back to Kadic for her in Distant Memory.
Jeremie's mother has yet to be seen in the show, though she was mentioned in Distant Memory.
It is worth noting that in the French Dub, Michael Belpois' name is spelled as Michel Belpois.
