Knuckle seed

Knuckle seeds are items that, when used, turn affected Pikmin's leaves, buds, or flowers into fists and make them adopt a fighting stance when standing still. The knuckle seed makes thrown Pikmin have a straight trajectory and inflict great impact damage. When Pikmin players get this power-up, they inflict massive combo damage and can perform a special attack.

In Pikmin: Neo
The Knuckle Seed is a species of power pod appearing in Pikmin: Neo. It is a hardy brown bulb appearing in a small black flower, with the bulb resembling an enclosed fist. They grow in dry areas such as deserts and canyons and tend to grow in small groups. When harvested, they can be converted into a substance called knuckle nectar, which is an orange, honey-like substance that, when applied to Pikmin, changes their leaves, buds, or flowers into enclosed fists similar in shape to the bulb the nectar is made from. The throwing arcs of affected Pikmin are heavily reduced and appear as a straight line. However, they make up for this by being able to become much faster in attack and movement speed, making them extremely well-suited for battling far-off creatures and carrying items back to the ship.
