Sonic: - Sonic would be quite intrigued by the Monsters of various threats dying for Saitama and Team Sonic. As a speedster, he loves challenges and thrives on competition. So, seeing Saitama easily defeat such powerful opponents would definitely pique his interest. - He would probably have a mixture of admiration and envy towards Saitama's unbeatable strength. While he values his own speed and agility, Sonic may also aspire to have a fraction of Saitama's raw power. - Sonic might even attempt to challenge Saitama to a fight out of curiosity, hoping to test his own limits and see if he can match up to the Caped Baldy's strength. However, he would probably realize that Saitama is simply on an entirely different level and may ultimately accept defeat. - Overall, Sonic would likely view Saitama as a formidable ally and an inspiration to push his own limits even further. One Punch Man characters (e.g., Genos, Tornado, Bang): - Genos: As Saitama's loyal disciple, Genos would be in awe of his master's abilities. Witnessing the Monsters of various threats effortlessly being defeated by Saitama and Team Sonic would only further solidify his admiration for Saitama. Genos would probably use this as motivation to train harder, hoping to one day reach a level remotely close to Saitama's. - Tornado (Tatsumaki): Being one of the S-Class heroes with immense psychic powers, Tatsumaki may have mixed feelings about the Monsters dying for Saitama and Team Sonic. She may feel jealous over Saitama's effortless accomplishments since she often relies heavily on her powers to defeat her enemies. However, deep down, she would acknowledge that Saitama's strength is on a whole different spectrum. - Bang (Silver Fang): Being a martial arts master and a mentor figure in the One Punch Man world, Bang would likely see Saitama's power as unattainable and purely extraordinary. He would probably take it as a valuable lesson that there are levels of strength that ordinary humans cannot reach, regardless of their martial arts prowess. - Other characters like King (with his fictional reputation as the strongest), Atomic Samurai, and Child Emperor would exhibit various reactions, but they would all ultimately recognize Saitama's unmatched power and, if anything, their own limitations in comparison.
