No not pyrotechnics, that's just the awakened ability of his fruit. When he changes the face to someone else, he completely gains all abilities they have, including whether they have a DF ability or not. When he changed to Sabo, he becomes a 'vessel' with no DF powers, and so he could eat the Mera and gain it's powers. Now whenever he changes his face to Sabo, he has access to Mera's powers.

Bon-chan for pirate king! He's waaaay stronger than BB now. He can have an unlimited number of DF powers!
