This version of Michael Bachelor is hidden within the game's files, and he can be only seen in SimPE. He looks very similar to his counterpart, except that he wears a purple and white track suit and has medium skin, and dark blue eyes. Unlike his counterpart, he has no relationships with any other Sims in the family tree and he does not have any memories of them and of his life.
Strangely, this version of Michael has genetics for red hair. Unlike his playable counterpart, this version seems to use one of the two broken face templates, though it's not possible to know exactly which, due to missing character data.
However, if the player checks the Sim Relations resources with SimPE this version of Michael actually had relationships with the Caliente, Goth and even other unrelated families, though none of those show up in his Sim Description resource.
Michael uses a character portrait pose that was discontinued during development. Oddly, this Michael had a very high relationship with his sister-in-law, Nina Caliente. In fact, he had a much better relationship with Nina than with his own wife.
He has unrecognized relationships with the Crumplebottoms, the Goths (except Mortimer), Jeff Pleasant, and Diane Pleasant. This Michael's personality is very different when compared to Michael Bachelor's personality in The Sims.
