Magnifying-Glass Damage

Wolf takes damage, because he is out of view.

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, damage stops. Hoop damage is present in both Melee and Brawl. It was never mentioned on the Smash Bros. DOJO!!, until April 14, 2008. Hoop damage occurs in every mode, except for Training Mode.

In SSBM, the "hoop" was called the Magnifying Glass, as evidenced by the Lost In Space bonus.
