Froppy Style is an alternative method of using Blackwhip developed by Izuku, which consists of shooting a tendril from his mouth instead from his arms as usual. This style is named after his classmate, Tsuyu Asui. Izuku was inspired by Tsuyu's ability to use her powerful extending tongue granted by her Frog Quirk, after having asked her for help with his training with Blackwhip.
Izuku first employed this Super Move during the Paranormal Liberation War. After his arms ended up broken and disabled after his confrontation against Tomura Shigaraki, Izuku used Froppy Style to help Shoto when he was facing Dabi. Izuku would use it again to try and stop All For One when he escaped after taking over Tomura's body.
