Emo Corehog has no passive capabilities.
- Explosive Quills: The Emo Corehog fires its quills into the air, which land at the player's location; a crosshair will appear on the ground to indicate where exactly. Although the quills will not initially do any damage, after flashing a few time they explode, damaging the player. Neku can easily dash away from the quills to avoid this, but his partner (excluding Joshua, who can avoid them with his levitation ability) must attack and destroy them to avoid being damaged.
- Quill Wall: The Emo Corehog turns its back to the player then expands its quills, causing damage upon contact.
Since the Emo Corehog doesn't move around very much, the player should keep their distance and use negative (long-ranged) psychs. However, they should keep moving in order to avoid its Explosive Quills attack.
