When Mewtwo is outside the camera view boundry, he takes hoop damage.

Luigi takes hoop damage because he is outside of the normal viewing boundary.

Magnifying-Glass Damage, also known as hoop damage, is the damage that a character receives when they are out of the camera's boundaries but not at the blast line. The character is still shown, but only inside a small "hoop" at the edge of the camera boundary. The damage is applied at a rate of 1% per second to prevent players from simply hiding near the blast lines of a stage. Once a character reaches 150%, however, hoop damage stops, meaning that stalling is still possible in Sudden Death. Hoop damage is present in Melee, Brawl, Smash for 3DS/Wii U and Ultimate. It was mentioned on the Smash Bros. DOJO!! on April 14, 2008. Hoop damage occurs in every mode except for Training Mode.

In Melee and Smash for 3DS/Wii U, the "hoop" is called the Magnifying Glass, as evidenced by the Lost In Space bonus and Magnifying-Glass Damage tip.

In Brawl and Smash for 3DS/Wii U, Meta Knight and Kirby have up throws that go beyond the upper blast line, but hoop damage is not taken.

In the Subspace Emissary, if Player 2 is in a situation that would usually trigger hoop damage, they will often instead Space Jump.


Jigglypuff's eyes while sleeping are open in the magnifying glass hoop.

  • In Melee, characters in the Magnifying Glass have a blockier, lower-resolution model compared to ordinary gameplay. These models cannot properly emulate some animations, such as blinking, and the use of some moves or attacks can result in unusual visual behaviour, such as Jigglypuff keeping its eyes open when using Rest.
    • These lower-res models are also used to render the water's reflection effects in Fountain of Dreams; as a result, the reflections in the water can have unusual visual abnormalities.
  • In Super Smash Bros. Ultimate, the hoop gets smaller the closer you get to the blast line, flashing when you are about to touch the line.
