(12 pages/66 panels/2,389 words)

Plot Synopsis

At a meeting of the Legion of Super-Heroes, only a few members are present because most are "visiting different planets on various space missions." Suddenly, Cosmic Boy's megnetic powers go haywire, destroying a robot cameraman there to to record the meeting "as a stern warning to interplanetary crooks." In rapid succession, Sun Boy, Lightning Lad and Saturn Girl each experience power malfunctions. With no other recourse, Saturn Girl pulls down on a lever labled, "Pull down to summon Superboy."

Meanwhile, in the 20th century, Superboy, in his guise as Clark Kent, greets Lex Luthor as the latter is being released from the Smallville Reformatory. Luthor brushes aside Clark's good wishes and vows revenge on Superman, once both grow to adulthood, of course.

Back home, Clark is checking in on Mon-El with his hand-held Phantom Zone viewer, when his signal lamp goes off, summoning him to the 30th century.

Superboy arrives in the future just as Lightning Lad is inadvertantly blasting apart the Legion Clubhouse. As he makes repairs with his "super-friction," Sun Boys power again goes awry, causing him to fly off, where his super-heat melts a mountain-top glacier.

The World-Wide Police then show up with an ultimatium. Because of the danger posed to the public by the out-of-control Legionnaires, they will be exiled from Earth if they cannot regain mastery of their powers in one hour.

Superboy begins to examin the Legionnairs with his e-ray vision, checking for signs of infection, when Urthlo shows up. Wearing a lead mask to conceal his identity, Urthlo boasts that he can control the Legionnaires powers and sets about to prove it, also using his green kryptonite vision to manhandle Superboy.

As the Legionnaires flee, Superboy obeys Saturn Girls command to burrow into the ground for a buried chest, but he is dubious of her command to use what he finds there - a Phantom Zone porjector. The Legionnairs urge Superboy to follow Saturn Girl's instructions and he summons Mon-El from the Zone.

Mon-El immediatly succombs to lead poisoning, but Saturn Girl gives him "Serum XY-4." His symptoms now gone, Mon-El makes short work of Urthlo, who has just caught up to the team.

Everyone's joy is quickly dampened, however, when Saturn Girl explains that the serum will only work for "just a few minutes." Before he "dies" Urthlo explains that he was created by Lex Luthor and sent into the future to destroy the Legion since they are "so dear to the heart of Suerboy."

The World-Wide Police life their exile order, Mon-El is inducted into the Legion before being sent back into the Phantom Zone, and Superboy returns to the 20th century.
