The Whammer appears as a blue and green hammer, with logos plastered over most surfaces.


"These bulky ARMS shrug off attacks and give great peace of mind! Originally developed for construction, they're now refined for competition."
Official Description

  • The Whammer hones in on the targeted enemy Fighter, appearing and then smashing them from above, like a hammer.
  • It can be curved to change which direction it travels towards the targeted enemy Fighter.
  • When charged, it moves quicker, gains size and stuns stuns the enemy Fighter on impact.
  • A Rush will increase the weight class of the projectiles to S.Heavy for the duration of the attack.
