After the attack on Merone Base and the Phantom Knight's defeat, Bligganteth deploys the Mechanimal Beasts around Namimori in hope of defeating Tsunayoshi Sawada. After their failure, he becomes a Half-Mechanimal Beast along with his top two Officers Biokilulu and Devolt and proceeds to attack the Vongola Hideout, only to be stopped in the end by Tsuna and his younger brother, Solte.
- Not only Storm Flame, Bligganteth also holds a mysterious black flame that looks like the Vendice's Flame of Night. The flame also has green-like lining on it.
