Clipped from Wikipedia: In the 30th century, Cosmic Boy and his girlfriend Night Girl (of the Legion of Substitute Heroes) have returned from a journey to 20th century Earth, where they were attacked by the Time Trapper and found history altered such that Superman never had a teenage career as Superboy.
Time Trapper recalls how he created a "pocket universe", with its own Earth, its own Krypton and its own Kal-El. In this pocket universe, Kal-El became Superboy at the age of eight, and it is to this universe that the Trapper has directed the Legion whenever they have travelled through time.
Superboy explains to the Legionnaires that the Time Trapper protected Earth in his era from destruction during the Crisis, and promised to keep it safe in return for Superboy's cooperation in defeating the Legion.
When they find the Trapper, they engage him in battle, inadvertently smashing the machine that protected the pocket universe Earth from the effects of the Crisis. With the red skies and antimatter returning (and with Brainiac 5 unable to repair the machinery), Superboy replaces the damaged unit with his own body. The gambit works and the Earth is saved, but the Boy of Steel is gravely weakened.
With the Trapper having now made time travel perilously unsafe, Superboy flies the Legionnaires back to the 30th century, carrying the Time Bubble himself. Shortly after their arrival, Superboy dies in Mon-El's arms. The entire Legion mourns his passing, remembering him as "the greatest hero of them all."

Clipped from Wikipedia:
...in then Superman: Following Superboy's disappearance from the pocket universe Earth, the Lex Luthor of that world is tricked into releasing Kryptonian criminals General Zod, Quex-Ul and Zaora from the Phantom Zone. They proceed to lay waste to the planet, eventually killing its entire population.
Having been summoned from the regular universe by Luthor and Supergirl, Superman executes the genocidal killers using green kryptonite, and brings Supergirl (a protoplasmic duplicate of Lana Lang) with him back to his own Earth
....in the Legion of Super-Heroes: While the entire Legion mourns Superboy's death, four members are particularly outraged: Saturn Girl (one of the three founders who invited Superboy to join), Brainiac 5 (who now realizes that all of his theories about time travel are incorrect), Mon-El (who regards Superboy as a brother), and Duo Damsel (who considers Superboy to be her first love, having once had an unrequited crush on him).
The four secretly enter into a conspiracy to attack and destroy the Time Trapper at the End of Time. With the assistance of Rond Vidar (who reveals himself to be the Green Lantern of Sector 2814), they barely succeed. However, another one of Duo Damsel's three bodies is killed, leaving her with only one.
Dork Note: This would be a great volume 2 to this death filled story arc.

Writer:Mike Richardson and Randy Stradley Artist: James Dean Smith Publisher: Dark Horse Comics (1986) Includes: Boris the Bear #1-12
Clipped from Wikipedia: Starting in 1986 and created by James Dean Smith and Steve Mattsson, Boris the Bear was the second title published by Dark Horse Comics. Telling the story of an anthropomorphic bear, who is soon revealed to be a robot, the book parodied many other comic book characters while also satirizing the comic book industry as a whole. The character’s popularity led to parodies of Boris himself and “revenge” stories appearing in titles such as Blackthorne Publishing’s Laffin’ Gas and Eclipse Comics’ Adolescent Radioactive Black Belt Hamsters.
In 1987, a disagreement with Dark Horse, over the direction of the title, convinced Smith to take Boris back from Dark Horse after the twelfth issue, and begin self-publishing the book under his own Nicotat Comics banner. Eventually, despite Smith having the title plotted through the fortieth issue, Nicotat ended its run with the thirty-fourth issue in November, 1991.
In April, 2007 James Dean Smith began self-publishing again under the name Oasis Comics. While it seemed, at the time, that Boris had returned to comics after a ten-year hiatus, no more issues of the title have been published and the character has not appeared since.
