From the Super Mario Wiki
Doctor Finale is Dr. Mario's Final Smash in Super Smash Bros. for Nintendo 3DS / Wii U and Super Smash Bros. Ultimate. The move operates identically to Mario's Mario Finale, with Dr. Mario firing a pair of giant Megavitamins that push back any opponents in their path, damaging them in the process. While the moves behave similarly, Dr. Mario's deals greater damage and knockback.
