Saitama vs. Mosquito is a fight fought between Saitama and a mosquito.
As Saitama was watering his cactus on the balcony, he was lamenting how powerful he has become and how now everything is too easy when a mosquito lands on the back of his hand which he then swats. The mosquito is seemingly unharmed, much to Saitama's distraught.
After chasing the mosquito and getting some bug spray in his mouth, he meets a young cyborg named Genos. When Genos warns Saitama about the large swarm in front of them, the swarm dispatches when Genos uses Incinarate to destroy the swarm, burning Saitama's clothes and leaving him naked.
