Double
Species: Two monozygotic twins sharing a single consciousness
Double is basically two identical twins operating as one mind—which is already pretty wild on its own. What makes them interesting is the stark contrast between how they act and what they're actually like underneath.
On the surface, they come across as playful and kind of childlike, with that innocent energy you'd expect from kids just messing around. But that's only half the story. Paired with that innocence is a genuinely evil streak and a love of destruction for destruction's sake. Fans often note that this combination—the giggling playfulness mixed with real malice—is what makes them such an unsettling presence.
