'Cosmo Slash' (コスモスラッシュ) is a sword-type attack function introduced in the Danball Senki W series.
When activated, the user gathers energy particles at the tip of its two swords. Then, it high-jumps and charges the energy to the swords' tips. After the energy is fully charged, the user returns to the ground through slaming the ground, unleashing the shockwave, dealing great damage. It was shown that this Attack Function is as strong as Zenon's Attack Function where it can smash a door down.
