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, Leons can avoid detection by camouflaging. This way, Leons can sneak around the playable characters and then attack with their tongue or tail lashing. Otherwise, the player can easily destroy them using any regular attack when they are visible.

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.

Powers and abilities

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