One Punch Man Manga Online Chapter 21

In Chapter 21, titled “Giant Meteor”, the Hero Association detects a massive meteor heading straight for City Z — large enough to wipe out the entire city. They immediately dispatch S-Class heroes, including Genos, Metal Knight, and Bang (Silver Fang) to stop the disaster. Genos makes a brave attempt to destroy the meteor with his full firepower, while Metal Knight arrives to test his new weapon systems, caring more about data than saving people. Despite their efforts, the meteor remains intact — until Saitama leaps in and casually punches it into pieces, saving the city at the last second. However, the fragments still cause serious damage, and people blame Saitama, thinking he made things worse. Once again, his heroism goes unrecognized, frustrating those who know the truth — especially Genos.
