The Newtron[2] (メレオン[3] Mereon?) is an enemy that appears in the Sonic the Hedgehog series. They are a mass-produced, chameleon-based Badnik model created by Dr. Eggman. Usually coming in two types, the Newtrons can camouflage themselves.


Newtrons are based on chameleons. They have a head, a stripy tail and four white feet with three fingers. One of these fingers are backwards so the Newtrons can get an extra grip. They also have yellow eyes with small pupils and a brown and sharp parietal crest. Newtrons come in two color varieties: green and blue. The green variation has yellow eyes, while the blue varitation has red eyes.

Newtrons in Sonic the Hedgehog 4: Episode I are more smooth and have detailed limbs. In Sonic Generations though, they are more mechanical and both varieties has cyan eyes. Newtrons in Sonic Lost World are slightly smaller than previous models and have cyan eyes with yellow sclera.

Game appearances

Sonic the Hedgehog (1991)


Newtrons made their first appearance in the original 16-bit version of Sonic the Hedgehog as enemies. In this game, they come in two varieties, both of which appear in the Green Hill Zone.

In gameplay, the Newtrons hang out on the side of cliffs and remain invisible until the playable character approaches them. Their behavior from there depend on their colors:

  • Green: These Badniks never move from their wall. After becoming visible, they will spit a ball of energy at the player before turning invisible again. Once vanished, these Newtrons cannot be destroyed even if the player attacks the area where they are hiding.
  • Blue: After becoming visible, these Badniks drops from the wall and morphs into a rocket, which chases the playable character in a fixed horizontal line without returning to their wall to turn invisible again. The blue variety is easier to deal with as it can be attacked, unlike most of its green counterparts.

Both of these badniks can be destroyed with the Spin Jump as they starts to appear on the wall. On some occasions, the player is unable to destroy green Newtrons depending on their placement in the Zone.

In the 8-bit version of the game with same name, only the green variation of Newtrons appear at Jungle Zone, although they have the same attack patterns as their 16-bit counterpart. However Newtrons do not have Animals inside of them as power source like many other Badniks in the Master System and Game Gear titles.

In the Nintendo 3DS version of Sonic Generations, both blue and green Newtrons appear in Green Hill Act 1. Despite their redesign for the game, the Newtrons have the same attack pattern as in their first game and are placed in the exact same places. However, none of Newtrons contain Animals.

Sonic Lost World

In both versions of Sonic Lost World, the Newtrons regain their original design, although they are smaller. During the game, it turns out that the Badniks, the Newtrons included, got hijacked by the Deadly Six.

Green type Newtrons appear in Windy Hill Zone 1 and Sky Road Zone 1 in the Wii U version, and in Windy Hill Zone 1 and 2, and Silent Forest Zone 2 in the Nintendo 3DS version. Green Newtrons mostly have the same attack patterns as in Sonic the Hedgehog (1991), meaning that they turn invisible, hang on walls and shoot small projectiles at the player. These Badniks can be defeated using the Focused Homing Attack. Also, in this game, they again release Animals upon their defeat.

Sonic Mania


In Sonic Mania, and its expansion Sonic Mania Plus, the Newtrons appear as enemies. As far as designs go, they look exactly like they did in the original Sonic the Hedgehog. In these games, they only appear in Green Hill Zone.

In gameplay, the Newtrons again come in two color variations. Their attack patterns are also the same as in their debut game: in addition to staying cloaked until the player approaches, blue ones will transform into missiles and jet along the ground, while green ones appear just long enough to fire an energy blast. Also, upon its defeat, a Newtron will release an Animal.

Powers and abilities

Newtrons possesses optical camouflage that let them camouflage themselves accordingly to the wall they are on and phase out of sight. They have also demonstrated two consist abilities which are sometimes exclusive to the color of their model:

  • The ability to spit balls of energy from their mouth
  • The ability to transform into a chameleon-shaped rocket, granting them flight
