Lurchthorns (トツコツ Totsukotsu) are Forces of Nature enemies introduced in Kid Icarus: Uprising. They can be considered physically equivalent to the Underworld Army's Fire Wyrm, although their attack strategies and weaknesses are much different. These large creatures resemble skeletal fish with five visible bone-like structures underneath their body segments. Unlike the Fire Wyrm, Lurchthorns primarily use projectile attacks, which are unleashed from the eyes on these segments. In contrast to its Underworld equivalent, the monster’s main weakness is actually its head rather than its body.
Lurchthorns are uncommon enemies that first appear in the aerial mission of Viridi, Goddess of Nature.
This string of cannons lies in wait until an enemy draws near, at which point it activates and speeds through the air. The turrets on its joints can be destroyed, but targeting the head is the most effective strategy.
Is it a bird? Is it a plane? No, it's...some kind of giant fossilized fish. Lurchthorns fly around, shooting at anyone who strays too close. Each of its segments attacks separately, so the more it has, the more dangerous it is. To get rid of it quickly, take out the head—that'll kill off the entire Lurchthorn in one go!
