Vanish Mario

Vanish Mario (referred to as Invisibility Power in the Super Mario 64 DS manual) is one of Mario's special forms from Super Mario 64. Mario can transform into it by collecting a Vanish Cap, found inside blue ! Blocks, which are activated by triggering the ! Switch in the Vanish Cap Under the Moat secret area. As Vanish Mario, he is invisible to enemies (and transparent to the player), and is thus able to pass by them completely ignored and unharmed. In addition, he is able to pass through cages, ice and certain walls. However, he can still be defeated by drowning, being crushed, or falling from heights.

Vanish Mario can combine his Vanish Cap with the Metal Cap to become Vanish Metal Mario, which will protect him from drowning or suffocating, while maintaining the ability to go through certain walls.

In Super Mario 64 DS, the Vanish form is granted exclusively to Luigi; however, the differences in terms of gameplay, aside from Luigi's slightly different handling, are subtle. As the Vanish Cap is absent in the remake, a Power Flower, which are typically found in red ? Blocks, is required for the transformation. Additionally, Vanish Mario can walk through ice, whereas Luigi cannot. However, Luigi cannot be seen by Mr. I and can pass through walls and cages vertically or horizontally, while Mario can do it only horizontally. Also, Vanish Mario is transparent, but Vanish Luigi is dithered.

In Paper Mario, using a Repel Gel or Outta Sight incidentally gives a similar effect. Enemy attacks will pass right through Mario.
