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' Sabo who had 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!
