[2] Believing Ultra Boy to be dead, the Legionnaires hold a memorial service and erect a statue of him in the Hall of Heroes.
The Legionnaires are unable to destroy the energy chains, but Saturn Girl tracks Grimbor to his stronghold near the North Pole.
He utilizes super-strength, invulnerability, super-speed and vision powers, making him seem familiar to Bouncing Boy and Duo Damsel.

Travelling back to 20th century Smallville, he tried to enlist Superboy's help, but unintentionally superimposed his memories over those of the Boy of Steel.

Fourteen years prior to the publication of this story arc, DC Comics presented a two-part tale called "The Adult Legion".
[11] It features one of Superman's encounters with the Legion of Super-Heroes as adults, and foreshadows several plot twists which occur in the years that follow.
For years, writers are careful to ensure that subsequent storylines are consistent with the Adult Legion tale's vision of the future.
One of the items seen in the story is a memorial statue of a previously unseen Legionnaire named Reflecto, who was said to have been "killed in a duel with the Molecule Master".
In publishing "The Exaggerated Death of Ultra Boy", the Legion creative team fulfills this prophecy, as the implosion of the Molecule Master android destroys the Reflecto personality.
In 1983, the team depicted in "The Adult Legion" are revealed as inhabitants of a parallel Earth, freeing writers to ignore the story altogether.
