Nen Type: Conjuration
Welfin's Abilities:
Missileman (卵男ミサイルマン Eggman) Type: Conjuration Welfin conjures an organic-looking missile launcher on his back with a shrunken head and four alien limbs, each holding a missile. The ability has 3 steps:
- Welfin establishes a target.
- The missile is loaded with a question or an order.
- If the target lies or defies the order, the attack begins.
If all the steps are executed correctly, the missiles continuously chase the target until they hit, even if Welfin himself can no longer sense the target. However, it is possible for the ability to misfire, which occurs when Welfin incorrectly identifies the target. Furthermore, the ability does not prevent the target from attacking Welfin except through deterrence, which means that if they are willing to be hit by the missiles, they will be able to strike first. The ability also has a long set-up and is difficult to use stealthily, since it requires a verbal exchange. These weaknesses led Welfin to look down on Missileman, prompting him to use it only in negotiations.
The missiles explode upon impact, implanting live Black Centipedes (黒クロ百足ムカデ, Kuro Mukade) in the target's head instead of dealing lethal damage. The centipedes grow by feeding on the target's defiance, inflicting excruciating pain until they kill the target. Should the target attempt to kill Welfin, the centipedes will instantly grow to fatal size, causing the death of the host and preventing them from carrying out their attack. Welfin himself is unable to remove the centipedes once they are inside the target. However, his feelings of defeat and sincerity harm the centipedes to the point that they can kill them, causing them to disappear. Welfin himself was originally unaware of this aspect of his ability.
