Beast Soul: Weretiger (ワータイガー Wā Taigā) is a Beast Soul Spell.
The user transforms their body into a Weretiger, a feline humanoid. The user's hair turns slightly darker and becomes longer like a mane. As this is a speed-type Take Over, it grants the user enhanced speed.
Enhanced Speed: Being a speed-type Take Over according to Mirajane, this allows the user to move faster when they employs it. It's currently unknown to what degree this form boosts his speed; however, an S-Class Mage specializing in martial arts like Bacchus was shown capable of effortlessly avoiding Elfman's melee attacks even in such state.
