Saitama is immune to heat, cold, electricity and the vacuum of outer space. In the intro, he took a lightning bolt head-on unscathed, and something like that can reach 5 times the temperature of the Sun's surface and carry a potential of 100 million volts. Sure, the air might insulate it, but not when it reaches a solid object and strikes it for longer than what is necessary.

Saitama survived the cold vacuum of outer space, as seen when Boros punched him into the moon.

In the intro, Saitama was seen jumping in the vacuum of outer space without the aid of a medium.

Saitama is completely invulnerable regardless of what you throw at him. What's worse, if you hit him, he will hit back with twice the force of whatever you hit him with.
