"Tears of Regret" (悔し泣き, Kuyashinaki, Tonari: 139) is the 98th chapter of the One-Punch Man manga series.

Summary
G5 encounters Child Emperor and Waganma after destroying the former's Radio-Controlled Sentry. He is able to resist the attacks of Child Emperor's Enemy Machine Disabling Device: Bug Kun and swiftly destroy it. G5 battles the newly combined Underdog Man, Mad Dog Underdog Cerberus, while hampered by Child Emperor's bird lime missiles. As G5 battles Mad Dog Underdog Cerberus, Child Emperor and Waganma escape.

They come across Phoenix Man's shredded body and Waganma mentions that he recognizes the costume from a comedy show called "Animal Kingdom". The character had an ability to revive itself no matter how it dies. As Child Emperor ponders on the information, Phoenix Man suddenly arises into a new, stronger form. Child Emperor confronts the monster and uses 5 layers of his transparent film but is broken through by Phoenix Man's Beak Attack. Frustrated at his uselessness, tears flows down his cheeks and Child Emperor is forced to summon his ultimate weapon, the mecha Brave Giant. However, Phoenix Man correctly deduces that the mecha has limitations and Child Emperor is informed of Brave Giant's activity limit of 2 minutes and 38 seconds. Child Emperor reaffirms himself that the monster must be dealt with as soon as possible.
