When Homer was dying, he gave Jack Strand, who was engaged to his niece Diana Carlin, a special gem. Homer explained the gemstone will protect Strand from Psyk, a villain from the fourth dimension, the world of the subconscious, who sought to conquer the third dimension.

Upon learning of Jack inheriting her uncle's jewel, Diana demanded it back, but her fiance refused. Strand eventually discovered that Diana was in fact working with Psyk. Jack went to the fourth dimension and defeated Psyk and won Diana back.

In his later adventures, Jack dealt with the aquatic race known as the Milo.
