Needle (Erizo in Spain) is one of Kirby's copy abilities. It debuted in Kirby's Adventure. It is a defensive ability, much like Spark or Freeze. With it, Kirby covers his body in many retractable spines. The ability impales any enemy that draws near, so in most cases, Kirby can only be harmed by projectiles. In Kirby: Canvas Curse, Needle Kirby's body is not only spiky enough to heavily damage enemies, but can also grip tightly to walls and other such surfaces. In Kirby's Return to Dream Land, there is an attack where Kirby turns the needles on his helmet into one large drill, hitting enemies directly above him. He can also roll along the ground while covered by the needles and firing small spikes from around his body at enemies.
The length of Kirby's spikes vary from game to game. The most noticeable difference is between Kirby's Adventure and its remake, Kirby: Nightmare in Dream Land, where the short spikes in the original were changed to being over twice as long.
In games with ability hats, Kirby is sometimes portrayed with a pinkish-red helmet covered in spikes and occasionally with yellow skin as well. His spikes are either pink or a bright metallic gold. In games without ability hats, the spikes come out of Kirby himself.
Multiple pointy spikes come out of Kirby, jabbing any nearby enemies. The nature of the spikes differ across games. Several require holding the button to keep the spikes out, the rest use it as a toggle.
Kirby can roll on the ground even with spikes out.
Kirby can keep the spikes out as long as he wants.
Kirby can stick to vertical surfaces when the spikes are out.

Kirby's hat turns into one large spike and shoots straight up, attacking anything above him, similar to a Tick's attack.
Needle undergoes the greatest visual change in the anime. It retains the look from Kirby: Nightmare in Dream Land, with the helmet, yellow skin, and orange feet, but Kirby no longer turns into one giant spike ball (Spinning like one giant spike ball in the episode Flower Power). Instead, Needle is changed into a long-distance ability. The helmet also gains a white chin-strap, which is not seen in any of the games.
Kirby can launch the needles off the top of the helmet like tiny missiles, which he can then control. The needles 'grow back', but not always, leaving him defenseless at times.
In the transformation sequence, a flash of red lightning forms his helmet and changes his skin color. Needles appear from the helmet, which shrink to their usual size seen in the games.
