Newtron surprises Sonic again using optical camouflage to try and blast Sonic. He can also transform into a rocket and charge towards Sonic.

— Profile, Sonic the Hedgehog 4: Episode I website[2]

The Newtron[3] (メレオン[4] Meleon?) is an enemy that appears in the Sonic the Hedgehog series. It is 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 (16-bit)


The first appearance of this Badnik was in Sonic the Hedgehog (16-bit), where it served as an enemy. This time around, this Badnik is referred to as Newtron[3] (メレオン[4] Mereon?). In this game, they come in two varieties, both of which appear in the Green Hill Zone.

In gameplay, the Newtrons cling to the side of cliffs and remain invisible until the playable character approaches them. Their behavior from there depends 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 though, the player is unable to destroy green Newtrons depending on their placement in the Zone. When successfully destroyed though, they release an Animal and reward the player with 100 points.

Sonic the Hedgehog (8-bit)

In Sonic the Hedgehog (8-bit), only the green variation of Newtrons appear as enemies. The plater encounters them in Jungle Zone. However, they have the same attack patterns as their 16-bit counterparts; They cling to vertical surfaces while invisible, until Sonic approaches. They will then reappear long enough to shoot a mouth projectile at Sonic, before blending in with the background again, after which they cannot be destroyed. The only time they can be destroyed, is with a Spin Jump while they are visible. However, these Newtrons do not have Animals inside of them as power source like many other Badniks in the Master System and Game Gear titles. Regardless, destroying one rewards the player with 100 points.

Sonic the Hedgehog 2 (8-bit)

In Sonic the Hedgehog 2 (8-bit), the Newtron Badnik is known as Meleon (メレオン?) in the Japanese manual.[1] In this game, the Newtrons appear in Under Ground Zone, Sky High Zone and Green Hills Zone. This game also has the two variations of Newtrons, although the green ones have the same color scheme as the rocket-types. Both types have the same attack patterns from previous game, although none of them contain Animals.

Sonic the Hedgehog 4

In Sonic the Hedgehog 4: Episode I, only the green variety of Newtrons appears in Splash Hill Zone. They keep their attack pattern from their first game and can also transforms themselves into a rocket which moves in a horizontal direction along the platforms. They would also appear in Episode Metal Act 4 of Sonic the Hedgehog 4: Episode II.

Sonic Lost World

In the Wii U version, PC version and Nintendo 3DS version of Sonic Lost World, the Newtrons return as enemies, where they regain a smaller version of their original design. During the games' events, the Deadly Six hijacked all of Dr. Eggman's Newtrons.

Green type Newtrons appear in Windy Hill Zone 1 and Sky Road Zone 1 in the Wii U/PC 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 (16-bit), 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 every version of Sonic Lost World, the Newtrons release Animals upon their defeat.

Powers and abilities

Newtrons possess 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
