- Punish Mash (パニッシュマッシュ Panisshu Masshu): Has three variations depending on which function Baron activates from his Sengoku Driver.
- Squash: Has two variations. In The Fateful Sengoku Movie Battle, Baron swings the Mango Punisher, sending a projection of the Mango Punisher's head at the target. In Kamen Rider Taisen, Baron charges the Mango Punisher, hitting his enemy with a giant projection of the Mango Punisher's head.
- Au Lait: Baron swings the Mango Punisher around multiple times, growing in intensity, until he stops, making a giant projection of the Mango Punisher's head fire from the mace and slams into the target from an aerial angle.
- Sparking: Baron performs a powerful swing, sending a giant, more solid-looking projection of the Mango Punisher's head straight at the target.
- In Fresh Orange Arms is Born!, when Zangetsu decides to use Mango Arms, he calls it a power-type form.
