Super Cosmic Nova is a special move used by Gingka Hagane and his Cosmic Pegasus F:D.
Beyblade: Metal Fury
Powered by the Blader Spirits of everyone in the world, Gingka rides on Pegasus's Beast far up into the cosmos, getting off the ground using Shining Wing. They then fly through the Earth's atmosphere, into the opponent's Bey, using Cosmic Tornado to gain power. Finally, the Special Move forms and creates an extremely strong force, similar to that of Galaxy Nova.
Gingka only uses this in the final episode of Metal Fury.
