Saitama-sensei didn't have a mosquito fight in One Punch Superman because Saitama-sensei was a fictional character whose story and plot were adapted from manga and anime. In the manga and anime, Saitama-sensei did not fight mosquitoes. He won the game by relying on his strength and skills rather than relying on the help of mosquitoes.

Saitama is a very powerful hero in the One Punch Man universe. He can defeat any opponent with just one punch. He has a simple appearance and a somewhat laid - back personality.
It's likely Saitama would win. Saitama's strength is on a whole different level. He can destroy planets with ease. Naruto's power mainly lies in his chakra and ninjutsu. Although Naruto has defeated some very strong opponents, he has always had to strategize and put in a lot of effort. Saitama doesn't need any of that. His physical strength is so overwhelming that Naruto's attacks would probably be like mosquito bites to him.
You can start by looking on fanfiction websites like Archive of Our Own (AO3) or FanFiction.net. These platforms have a wide range of fanfictions about Saitama's powers. Just use the search function and type in relevant keywords like 'Saitama powers' to filter the results.
Sometimes King is paired with Saitama. King, known for his false reputation of being a super - strong gamer in the original story, could be in interesting interactions with Saitama in the fanfiction's gaming context. Maybe they compete in a gaming tournament within the fanfiction, and Saitama's effortless wins baffle King.
It's really hard to say. Goku has the ability to keep getting stronger through intense battles and transformations. However, Saitama has the power to defeat any opponent with just one punch. If we consider Goku's Super Saiyan Blue form, he has an incredibly high power level. But Saitama's strength has no known limits yet. It could go either way depending on the circumstances of the fight, like if Goku has time to power up or if Saitama can land his punch first.
They could fight over a shared resource. Say they both want to use a car they co - own at the same time. Or perhaps it's about loyalty. If one friend feels that the other has been more friendly with someone else and has neglected their friendship, it can start a fight. Sometimes it's just stress. If one or both friends are going through a tough time like problems at work or family issues, they might take it out on each other and start a fight.
Genos could be an unexpected opponent. He might be forced to fight Saitama due to some mind - control or a misunderstanding in the rules of the tournament. It would be really interesting to see how Saitama would handle fighting his own disciple, and how Genos would fare against his master's incredible strength.
