Question: is blast saitama with hair?
Answer: On the web comic series, Blast has a spiky black black hair and wore a superhero suit kinda similar to Saitama's. His hero job was more like a hobby to him. And his strength might be the same as Saitama's. Actually, 18 years ago, he saved a young Tatsumaki from a monster due to the sudden loss of her psychic powers.
