Alien Species

Biot-savartians, alternatively known as Electronians, are an alien species with magnetism powers from the desert planet Electrontare.[1]



Biot-savartians have large spikes on their shoulders, crab-like claws, and two toed feet. Their bodies are made of living alien metal[2] that is mostly colored black, while their chests, spikes, feet, and claws are yellow, and their head is silver and floats above their body.

Powers and abilities[]

Biot-savartians can manipulate metallic objects through magnetism, sending out electromagnetic waves to either draw metallic objects toward them of repel them away from themselves with equal ease. This magnetism can affect species that are mechanical in nature such as Evolved Sonorosians and Chronosapiens.[2]

Biot-savartians possess superhuman strength, and can use their magnetism abilities to peel away metal and overload machinery.

Biot-savartians possess enhanced durability, allowing them to withstand laser blasts without any major damage.

Biot-savartians are able to lift metal objects in the air and shoot magnetic waves as an offensive ability.

Biot-savartians can create magnetic fields, regenerate, and levitate.

Biot-savartians possess magnetoreception, meaning that they can act like a compass.[2]

Due to their heads not being connected to their bodies, Biot-savartians can survive in the vacuum of space.[2]


A Biot-savartian's head is magnetically floating over their body, meaning that it can be separated from the body. This would leave the body vulnerable and unable to reconnect with the head.

Because Biot-savartians do not have necks connecting their heads with their bodies, said heads can be flipped over and spun if something were to hit them.

A Biot-savartian's magnetism is ineffective against materials that are not made from metal.[2] They are also unable to lift certain objects seemingly metallic objects.[3]



  • The Omnitrix's Biot-savartian representative is named Lodestar, who first appeared in the Alien Force episode "Simple". He was originally unlocked in "War of the Worlds: Part 2" after the recalibrated Omnitrix was reset. Lodestar has appeared in almost every subsequent series except the reboot.
    • Lodestar has also been used by Vilgax's Bioid army. Despite not appearing on-screen, it is confirmed that Albedo can transform into Lodestar.
  • The name Biot-savartian comes from the Biot–Savart law, an equation describing the magnetic field generated by an electric current.
  • It is confirmed that the Omnitrix from the Ben 10 reboot contains Biot-savartian DNA.[4] Therefore, Lodestar is one of the countless aliens whose DNA pod was glimpsed in the episode "Innervasion Part 5: High Override".
