Amp: the electric ball that spins forever

EnemyAmpSuper Mario 64

Its name comes quite simply from the ampere. Introduced in Super Mario 64 in 1996, the Amp is an electric sphere that spins endlessly around its perch. This profile covers its lineage from the Spark of Super Mario Bros. 2, its design shift from gray to black, and the only way to neutralize it.

It spins, spins and spins around its perch, and if you so much as brush against it, bzzzt: meet the Amp, one of the most unkillable threats in the Mario universe.

Known as "Amp" in both French and English, this enemy is a small, metallic, invincible ball of electricity that patrols in circles around a fixed point. Here is its full profile, from the origin of its name to the only way to neutralize it.

An electric sentry born on Super Mario 64

The Amp makes its debut in Super Mario 64, in 1996. There it stands guard around platforms, pillars or narrow passages, in the shape of a metal sphere wreathed in electricity that traces fast, wide circles around a fixed object. You typically meet it above a bottomless drop or over dangerous areas, where a single jolt is enough to doom the player.

Its behavior is devastatingly simple: it never chases the player but follows an unchanging circular path. On contact it electrocutes Mario, deals damage and freezes him for a split second. Best to see it not as an opponent to beat, but as a moving trap to go around.

A name borrowed from electricity

The name Amp is no accident: it comes straight from the "ampere", the unit measuring the intensity of an electric current. In English as in French, "amp" is even its everyday abbreviation. It is a nod to the way Nintendo likes to name its enemies after what they are rather than after a complicated backstory.

That choice sums up the whole character: an enemy defined entirely by its charge. Good news for French-speaking players, the official name stays identical to the English one, with no translation or special adaptation.

The heir to the Spark from Super Mario Bros. 2

The Amp did not come out of nowhere. In look and behavior it descends from the Spark, the electric enemy introduced in Super Mario Bros. 2, where an electrified ball already circled the platforms and could not be beaten with a simple jump.

The Spark is regarded as the first in a line of "balls of electricity" enemies in the series, which also includes the Li'l Sparkies. The Amp reuses the idea of the impassable circle but remains a separate creature: a 3D rereading of the concept, specific to Super Mario 64. That kinship explains their shared signature, an electric halo and a patrol you cannot break through head-on.

From gray to black: a design that shed its skin

Originally, on Super Mario 64, the Amp is a gray sphere with red eyes, fitted with a wide red mouth, gray lips and odd white cross-shaped veins across its metal shell. The yellowish halo of sparks surrounding it is not just for show: it acts as a visual warning, alerting the player to the risk of electrocution.

The big makeover arrives with Super Mario 64 DS, in 2004: the Amp turns black, its yellow eyes widen, its mouth grows bigger and gains a tongue, its lips turn white and puffy, and the veins vanish. It is this black-and-yellow version that then becomes the standard, with a few exceptions such as the small black balls with red features in the Super Mario Galaxy.

The only way to neutralize it

Let us be clear: in the vast majority of situations, the Amp is quite simply invincible. Neither a jump nor a standard fireball makes a dent in it, so rule number one remains plain and simple avoidance.

There is one nuance, though, ever since New Super Mario Bros.: after electrocuting the player, the Amp loses its charge for a few seconds and becomes harmless to the touch. A brief window to slip through, but careful: that makes it harmless, not dead. It recharges right away and resumes its electric patrol.

To really destroy it, you have to bring out the invincibility arsenal:

• In New Super Mario Bros. (DS), only a Mega Mushroom or a Star (Starman) can finish it off.
• In New Super Mario Bros. Wii, you have to freeze it with an Ice Flower or a Penguin Suit and then land a ground pound on it, or touch it while under Star invincibility.

With no item on hand, keep these reflexes to cross its orbit unscathed:

• First watch its patrol: its path is always steady and predictable.
• Cross the circle when the Amp is at the point farthest from your path.
• Never stand in the middle of its patrol, the one spot it sweeps non-stop.

From Galaxy to Jamboree: a series regular

Nearly thirty years after its debut, the Amp is still a familiar face in Mario games. You run into it throughout the New Super Mario Bros. line as well as in Super Mario Galaxy and Super Mario Galaxy 2, where it patrols around the mini-planets.

It has also made itself a recurring spoilsport in the Mario Party series, right up to the very recent Super Mario Party Jamboree, released on 17 October 2024. In these party games it serves as a board obstacle or a minigame element, true to its role as an electric nuisance. Three decades of loyal service for one simple charged ball.

FAQ

• Can you kill an Amp by jumping on it?
  No. The Amp is immune to standard attacks such as jumps or fireballs. It can only be destroyed with an invincibility item (Star, Mega Mushroom) or, in New Super Mario Bros. Wii, by freezing it and then smashing it into the ground.
• Where does the name "Amp" come from?
  It comes from the "ampere", the unit measuring the intensity of an electric current, of which "amp" is the common abbreviation in English as in French.
• Which game does the Amp first appear in?
  In Super Mario 64, released in 1996. There it was gray with red eyes before turning black from Super Mario 64 DS in 2004 onward.
• Why does the Amp sometimes become harmless?
  In New Super Mario Bros., after electrocuting the player it loses its charge for a few seconds and becomes safe to touch, just long enough for you to get past. It then recharges right away.
• What is the difference between an Amp and a Spark?
  The Spark is the electric enemy from Super Mario Bros. 2 that the Amp visually descends from. They are two separate creatures all the same, the Amp being a 3D rereading of the concept introduced on Super Mario 64.
