Counter is Marth and Ike's Down Special Move in Super Smash Bros. Global Apocalypse. Marth or Ike will strike a pose and a small, metallic "chink" sound will be heard. For about a second, any attack that Marth or Ike is struck by other than a grab will turn him invincible for the duration of his retaliating swing. Marth's deals up to 7% damage, regardless of the attack, while Ike's deals back the same damage it reflected.
