Classification: Human hero
Threat level: God
Powers and abilities: Super strength, speed and durability, resistance to telekinesis.
Physical strength: At least moon+ level striking (Casually overwhelmed a blast intended to destroy the surface of the planet (just called planet destroying in the original version) and his punch still had enough force leftover to kill a planetary threat with its air pressure)
Destructive capacity: At least moon+
Durability: At least moon+
Speed: At least relativistic+, likely higher (Even assuming his jump from the moon to the earth took half a minute it would mean he impulsed himself at least around mach 40,000, effortlessly threw a rock faster than Geryuganshoop could, was stated by Murata that Geryuganshoop's near light speed attacks are "nothing" compared to Saitama and "a bad joke" in his eyes)
Stamina: Above average. Never really been tested since he hasn't been involved in exhausting nor considerably damaging fights, but he has kept up his rhythm after fighting for decent periods of time.
Standard equipment: None except his hero outfit (including cape) which isn't really of any special utility in battle.
