Super Burning Uppercut

Super Burning Upper is Zero Kurogane/Shinobu Hiryuin's combined special move that can only be used when Samurai Ifraid is in Synchrom with Saramanda.

Metal Fight Beyblade Zero-G
The bey catches on fire once it hits the opponent's bey. First, it circles the opponent's bey then the stadium at high speeds leaving a trail of fire behind it. The bey comes out to be a mixture of both Samurai Ifraid and Saramanda and goes through the fire the bey was circled with and hits it against the wall out of the stadium. The move was used in episode 10 of Beyblade Zero-G against Kite Unabara.
