Extremely powerful lightning magic.
Arcthunder (Japanese: ギガサンダー Gigathunder) is a potent thunder tome which debuted in Fire Emblem: Radiant Dawn and is present only in it and Awakening. As a counterpart to Arcfire, Arcwind and Shine, it acts as the game's third "stage" of thunder magic, superior to Thunder and Elthunder and surpassed in turn by Thoron.
Arcthunder will be part of Robin's neutral special move, Thunder, in Super Smash Bros. for Nintendo 3DS and Wii U. When charged up for certain periods of time, it will become a stronger thunder spell when released; Arcthunder will be the third and penultimate charging stage.
