Nayru's Love

Nayru's Love is an attack hailing from ' series also usable by Zelda and Sheik in the ' series.

Overview
The attack consists of the user surrounding herself with a blue crystal-like barrier for a moment, damaging opponents that make contact with it.

In Super Smash Flash
In the original Super Smash Flash, Nayru's Love is 's and 's down attack, in conjunction with Transform. Both characters perform the move in the same way, as the blue barrier appears around the user for about half of a second, dealing multiple hits to opponents touching the barrier, before disappearing as Transform is used. Zelda's version of the move deals 5% damage per frame with decent knockback to opponents hit, while Sheik's version deals 6% damage per frame with less knockback.

In Super Smash Flash 2
In the reboot, Super Smash Flash 2, Nayru's Love is no longer a part of 's moveset, now exclusively 's standard special move. Zelda now twirls around while the barrier is out, and miniature blue crystals twirl around the barrier as she does. The barrier stays out for about one second, and its effects are only active when it does. The attack can hit opponents multiple times, racking up to a total of 14% damage to an opponent with weak upward knockback if they are struck for the entire duration of the attack. The move also reflects projectiles, and it slows Zelda's descent when used in the air.

Origin
Nayru's Love originates as a spell used by Link in The Legend of Zelda: Ocarina of Time that is representative of Nayru, the Goddess of Wisdom. The spell is obtained from a Great Fairy in Gerudo Desert, making it one of the later skills Link can earn. The spell involves Link casting a large blue crystal around himself, which drains half of his magic meter (or a quarter, if upgraded) and lasts for one minute. Unlike in SSF and SSF2, it could not be used offensively; instead, Link is immune to all damage, but he can still flinch or be knocked down, and he cannot use magic to do anything else.

Trivia

 * Nayru's Love is the only attack in Super Smash Flash originating from the  series that is used by a character who could not originally use it, as it was previously exclusive to Zelda. This may have simply been done to hide the sprites of Zelda and Sheik so the transformation between them would not have to be sprited.
