Doctor Miguelito Loveless, Jr.

Doctor Miguelito Loveless, Jr. was the son of the infamous criminal genius Doctor Miguelito Loveless and the inheritor of his criminal empire and legacy which he oversaw alongside his sister Carmelita Loveless after his father's death. Much like his father before him, Loveless Jr. was an evil genius whose intellect and creativity was not only centuries ahead of his time but was even further ahead than his father, having successfully created bionic limbs, cloning technology and even recreating his father's lost formula for an atomic bomb.

Trivia

 * His mother is unknown, however he and his sister both had different mothers.
 * Despite both he and his sister looking only a few years younger than James West, Doctor Loveless, Sr. never made any mention of having children in the original show's run nor were they ever seen helping their father despite Jr. clearly having been close to his father.
 * It is possible they were living their own lives or studying at the time, or Loveless did not want them participating in his criminal affairs.
 * Strangely, in the film, Loveless, Sr.'s tombstone shows that he was only 32 at the time of his passing, yet both his children appear to be in their late 20s or mid 30s at most, making it impossible for him to have sired them unless they were victims of Loveless' own experiments.
 * Its more than likely that the date on the tombstone was simply an error on the film crew's part, as dates were often inconsistent even within the original show.
