Kefla vs. Vegito
Is Kefla more powerful than Vegito? No, Vegetto is not stronger than Kefla. Super Saiyan Kefla can easily be defeated by Super Vegito. Goku, despite his exhaustion as a Super Saiyan, was able to face Super Saiyan Caulifa and Controlled Berserk Super Saiyan Kale respectively.
Vegito’s Defeat by Buu
Some sources suggest that Vegito’s defeat was due to the chemicals and enzymes in Buu’s body, such as digestive enzymes that broke down Vegito for Goku and Vegeta.
Strength of SSJ2 Kefla
Kefla, the Super Saiyan 2, had the strength to kill Goku, the Ultra Instinct Sign, with a single blow. Although impressive, UI Sign Goku 2.0 inflicted severe damage on her and she couldn’t overcome his Imperfect Instinct Kamehameha.
