Electroblast, the strongest non-signature move Crepto based move.
Crepto is an Elemental Energy that comes from lightning and electricity. Crepto can be created simply by changing electrical energy to matter, which would change it by default to the solid form.
Users of Crepto are often called Creptomasters or even more commonly Electromasters. They have access to very powerful moves that can cause blackouts, short out machines, which can bring down Starships. Because of its power, Electromasters are banned from using their high level Crepto-based moves inside some universes.
