 As a result of Marvel Family foe Mister Mind eating aspects of this reality, it takes on visual aspects similar to the pre-"Crisis" Earth-S, including the Marvel Family characters.The names of the characters are not mentioned in the panel in which they appear, but a character visually similar to Captain Marvel Jr. appears.Based on comments by "52" co-author Grant Morrison, this alternate universe is not the pre-Crisis Earth-S.

Freddy Freeman first appeared in issue 13 of this book; he was shown crippled and in a wheelchair, the result of being inadvertently injured in a previous battle involving the Marvels.
