Fire Shield

The Fire Shield or Flame Shield is a power-up first introduced in Sonic the Hedgehog 3 and a variant of the standard Shield. In addition to serving as a one-shot barrier against damage and life loss, the Fire Shield negates flame-based damage, allowing characters to stroll across boiling lava and take flamethrowers to the face with a complete absence of concern.

While all variants of this shield prevent fire damage, in Sonic 3 & Knuckles the shield would be lost if the player took it underwater; and when playing as Sonic, holding a Fire Shield exchanged the Insta-shield move with a rapid horizontal fireball attack, allowing the hedgehog to barrel forwards and blast into enemies. Sonic 3D, the only other game to include the Fire Shield, had no double-jump attack and also no water to lose the shield in.

Other variants of the basic shield include the Lightning Shield, Water Shield, and Gold Shield.
