For the character in Sonic X, see Leon.

Leon (レオン Reon?),[1] is a recurring enemy in the Sonic the Hedgehog series. It is a mass-produced, chameleon-based robot created by Dr. Eggman which can camouflage itself.


Based on chameleons, Leons closely resemble Newtrons in design. By comparison, Leons have longer insect-like legs with gray and white weights as feet. Like Newtrons, they also have a long tail with a curled tip.

In Sonic Adventure, Leons possess a jungle green, gray and yellow color scheme, while in Sonic Advance, they possess a purple and orange color scheme. They also have shorter legs.

Game appearances

Sonic Adventure

In Sonic Adventure and Sonic Adventure DX: Director's Cut, Leons appear in the following Action Stages for each character:

Character Action Stage
Sonic Windy Valley, Lost World
Tails Windy Valley
Knuckles Lost World
Amy Hot Shelter
Gamma Windy Valley, Hot Shelter

In gameplay, the Leons have the ability to turn invisible to avoid detection and sneak on enemies with their tongue and tail lashing.

Leons only use their tongue attack in the Dreamcast version of the game. In Sonic Adventure DX: Director's Cut and the 2010 rerelease, Leons never stick their tongues out and instead continually fade in and out, tending to avoid the player. This altered behavior is due to the Badnik's invisibility timers not being adjusted to compensate for the increased framerate. As a result, it turns invisible too quickly for it to get a chance to attack, and therefore never attacks the player as a result.[2]

Sonic Advance


In Sonic Advance, Leons can be encountered in the Angel Island Zone. In this game, they simply crawl back and forth in gameplay. Their method of attack is lashing out with their large tongue when the playable characters are close. Using the Spin Jump or any melee moves defeats a Leon easily.

Leons have the ability to turn invisible to avoid detection and sneak on enemies. They also possess a long and powerful tongue and tail.
