|Real world information|
Oblivion is the alternate future version of John the Marksman. Oblivion is considered one of the most dangerous and powerful enemies John the Marksman has had difficulty facing. Oblivion is mentioned in Time Teleportation II but officially made his debut in the eighth episode of season one, Time Teleportation III.
Oblivion was born as John the Marksman and shared most of the same exact history as his alternate self, besides from a few differences.
After the concluding battle with LT Fan followed by his downfall, all the heroes of the Nickelodeon Fanonverse celebrated. During the festivity later that night, John met with Web covertly to discuss his potential proposal for world harmony. However, his plan to attain harmony involved an authoritarian despotism, something which Web significantly disagreed to. Infuriated, John left the party and headed for Nicktropolis to establish the collapse of the municipality, one of the first parts of his plan.
Together with his gang, the Union, John started civil uprisings and lethal riots and ultimately overthrew the government in the city. When word spread to the heroes, Web was one of the first to arrive on scene, and John and Web instantaneously clashed. John, however, was able to absorb some of LT Fan's power before he died and countered every single one of Web's attacks as a result. When Web was fatigued, John mimicked Web's powers and abilities and used them against him, viciously murdering Web and taking his head off. When reinforcements came, John brutally murdered them, which included SSK and Kirby. Thus, John adopted the new name Oblivion, as now all he stood for was pandemonium.
Oblivion is commonly seen as a power-hungry and sadistic villain of pure evil. Oblivion considers himself a deity, and believed he had evolved beyond a mere human being. He sought to show the world the true meaning of pain. Oblivion was even willing to kill Web, his former friend, to ensure the completion of his plans. He even went so far as to proclaim himself a "god of peace", that had to guide the world to maturity through pain. He felt that no one could understand true peace unless they understood "true" pain. Oblivion has become more and more ruthless, seeing people as tools to be manipulated or as enemies to be destroyed. While frequently arrogant about his own abilities and disrespectful of those he considers as weak, he is not above giving praise to his enemies.
