Angry Grandpa
CharacterAngry Grandpa is a monster from the One-Punch Man audiobook Sonic, Becoming Saitama, a former human whose rage against unruly children twisted him into a Mysterious Being before Speed-o'-Sound Sonic put him down.
Appearance
Before his transformation, Angry Grandpa passed for an ordinary elderly man, betraying nothing of the creature he would become.
Personality
A deep loathing for noisy, ill-mannered youngsters consumed him. He lashed out at disrespectful children and swore to drill manners into every kid in the area, so that none would ever again act as though the world were their personal playground.
History
The constant din of shrieking children and blaring music in public finally pushed him past his limit, and the ordinary man mutated into a monster. In the audiobook he clashes with Mumen Rider and holds his own, punching craters into the ground and shrugging off police gunfire without visible harm. His fury fed his strength, letting him convert built-up frustration into bursts of power beyond his normal ceiling, including a single blow strong enough to smash concrete. The rampage ended when Speed-o'-Sound Sonic, disguised as Saitama, took him out.
