Zero

Twenty-Fifth Baam Style - Floral Butterfly Piercing Technique Zero(0) (스물다섯번째 밤 류 공파술 제로(0)) is not a new type of Wave Piercing technique, but rather a version of the basic Wave Piercing technique performed in the state of Zero. It's weaker than Baam's normal Floral Butterfly Piercing Technique, but it's the version closer to consolidating his "basics". Baam was taught all these powerful techniques by force before, but now he's learning from Zero step by step but swiftly from the zero up. Baam created this technique after training under Ha Chai.

Tower of God: Part 3 - Deng Deng
The first time Baam used this technique is against Varagarv. Baam stated that he only used enough power to knock down Varagarv so he won't fight back. This implied Baam was holding back so it won't badly hurt Varagarv.

Tower of God: Part 3 - Heart
Baam used this technique again when he intend to wake up Baylord Yama. However, Yama was only able to wake up because Baam combined his "Zero" technique with Karaka's White Day. Karaka also noted that although Baam's technique isn't as strong as his, but it was unbelievably powerful for a Regular.
