Libra produces a huge blast of sonic vibrations that draws opposing beys towards it. A Bey caught in the blast would lose stamina and eventually stop spinning.
In Metal Masters, it is revealed that Yu is able to modify the frequency of the blast as well, causing it to change color.
Beyblade: Metal Fusion
Yu uses Inferno Blast to defeat Benkei, Hikaru, and Kenta in the Survival Battle and then defeats Gingka with it. He also uses Inferno Blast against Tsubasa, but fails and ends up in a tie.
Beyblade: Metal Masters
- In Metal Masters (during the battle for Team Gan Gan Galaxy's third member), Inferno Blast changes from green to yellow, then shortly to red, then purple before becoming rainbow colored. The change in color is due to the change in frequency of the vibration.
- When Yu uses Inferno Blast, the world surrounding it becomes dark, and daylight is somehow gone.
