Nosferatu is an HP-draining spell appearing throughout the Fire Emblem series. Although it has been classified as several different types of magic in its various appearances, the dark magic variant as in Fire Emblem Awakening appears as Robin's down special move in Super Smash Bros. for Nintendo 3DS / Wii U. When used, Robin traps an enemy in a dark field, dealing damage to them while healing himself. Any other opponents caught in this attack are knocked back without damage. Nosferatu can only be used four times, and can only be used again after a cooldown time of 40 seconds, the longest of any of Robin's attacks.
The first custom variant for this move is Distant Nosferatu, which can catch opponents from farther away, but has less of a damaging and healing effect. The second is Goetia, another dark magic tome exclusively in Fire Emblem Awakening; the move can pull in opponents and deals greater damage, but no longer heals Robin.
