Saitama can also hold his breath for indefinite amounts of time. He was only seen to be tired in Episode 6, and then he walked it off like it was nothing for him. After that, he was never seen to have ever become tired again.

Although Saitama sleeps and eats, he had used fasting as a method during his training. Whether he really requires them is completely unknown.

The reason Boros survived Saitama's punches was because Saitama was not serious enough. Also, Saitama is a parody, meaning, he is automatically stronger than any character you can think of.

Saitama is immune to cold temperatures, as he survived the sub-zero temperatures on the moon unscathed.

Saitama did not intend to run at light speed around City Z, as that would destroy everything around him.

Saitama defeated Garou, a user of Absolute Stamina.

Saitama countered a planet-busting attack, as seen in his final fight with Boros, who later clarified that his Roaring Whole Cannon would blow up the entire planet instead of cleaning its surface, and Saitama's countering attack wasn't even anywhere near his true strength.

Worse, Saitama has never reached his true limit, mostly because he has no limits to reach anymore.

Saitama is immune to heat energy overall, as seen when Genos unleashed his Incinerate move and killed all the mosquitoes. Saitama was engulfed in the flame, but he came out unharmed, just looking dirty.

Saitama allowed himself to be hit. That's how he works. He always hold back to get the thrill of fighting.

Saitama's nightmares don't affect him much, unless it's about boogers.

Saitama is invulnerable to almost all kinds of damage except pain from cat nails.

In the OPM verse, the limiter means everything. If you break the limiter there, you get unlimited power.

Saitama has difficulty holding back his infinite strength, as even when he holds back, he still tends to go overboard. And yes, he was about to effortlessly turn the Tank Top Brothers' hands into paste by simply holding them, and only the crowd's continuous shouting forced him to let go.

Saitama's weaknesses are pain from cat nails. And even then, it couldn't leave a single mark on Saitama's body.
