Biosfera

Biosfera (also spelled Biosphera) is a planet covered to some extent in jungle. Early Transformers refugees settled there and adopted beast alternate forms to better fit the environment. Their descendants eventually became distrusting of robots with vehicle alternate modes.
Fiction
Titans Return marketing material
Biosfera was the possible location of one of thirteen Titans, alongside Cybertron, Unicron, Dominius, Nebulos, Junkion, Antilla, Paradron, Caminus, Earth, Velocitron, Aquatron, Botropolis, Micron, and Gigantion.[1]
War for Cybertron: Earthrise marketing material
When the Ark detected energon on Biosfera, they dispatched the Clones Fastlane and Cloudraker to investigate. Unfortunately, after arriving they made contact with Decepticon Clones Pounce and Wingspan. Even more unfortunately, the Decepticons' beast modes gave them a distinct advantage in jungle warfare.

Notes
- The planet was first named (in Cybertronian writing) as "Biosfera" as part of a map on the back of the 2016 Titans Return Titan Force 3-pack. As the name evokes the word "biosphere", and the world is populated with animal-mode Transformers, Biosfera appears to be an alternate take on the "Beast Planet" archetype previously seen with planets such as Animatron (the only Cybertronian colony from Transformers: Cybertron otherwise absent from said map) and Eukaris (absent from the map, but already seen in Titans Return marketing material).
- The collectible map piece included with Earthrise Voyager Class Snapdragon spells the planet's name as "Biosphera". This is the only time this spelling is used, as the map included with the concurrently-released Galactic Odyssey Collection toys uses the original spelling.
