The Lightning Shield, otherwise known as the Magnetic 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 Lightning Shield attracts rings towards the player if they get close enough. It is often considered a particularly useful power-up because of this feature.
While all variants of the shield drag rings in, minor details differ from game to game. In Sonic 3 & Knuckles, the shield would be lost if the player took it underwater; and when playing as Sonic, holding a Lightning Shield exchanged the Insta-shield move with a sparking double-jump, enabling the hedgehog to leap much higher and potentially access otherwise difficult platforms. Finally, the shield made Sonic invulnerable to both electric damage (like the crackling sub-conveyor-belt floors in Death Egg Zone (S&K)), and, curiously, the spiked projectiles hurled by IceCap Zone's Star Pointer. While Sonic R kept being able to lose the shield due to falling in water, none of these features are in effect in any other game where the shield appears: namely Sonic Adventure, Sonic Adventure 2, the Sonic Advances 1, 2 & 3, and Sonic Rush.
