Blurr and Wheelie crashed on Io while delivering Metroplex's transformation cog to Earth, where they were attacked by the local wildlife. They were soon joined by Marissa Faireborne, courtesy of the locals' skills as kamekaze pilots. All three had to be rescued by the Autobots' current ride.
Io, the innermost of Jupiter's Galilean moons, served as temporary base for Admiral Winfield's Exofleet remnant in the first years of the Neosapien War. It became a critical base after the destruction of the Resolute and much of Exofleet during the Third Battle of Earth.
During the Blockade of Io, the Neosapien fleet placed Io under siege due to the belief that Winfield had a functioning GRAF Shield. When Typhonus learned that the shield was non-operational, he ordered a full scale attack. However, the Pirate Clans came to Exofleet's aid and inflicted heavy losses on his fleet.
Combined with the losses he had suffered from the aftermath of the Battle of Sinope, Typhonus chose to retreat. This allowed Exofleet to escape to Chaos. Although Io was later captured by Typhonus, it was never mentioned again as a vital location until in Titan A.E., the base was under attacked and finally destroyed by the Drej at the start of the Second Drej War.
Io was the innermost major moon of Jupiter, and one of several terraformed moons in the Solar System.
Io had a dry and airy environment, seeming much like a desert, though there were a few towns with roads. Large plateaus and cactus dotted the environment. The planet had police, the Io Police Department.
The Bebop crash-landed here after being involved in a hit-and-run while drifting towards Europa.
Io is the home of Lipole, psychotic alien bats that transform into missiles in Transformers: Universe.
- In real life, Io frankly doesn't need the missile-bats to be a bad place to crash. The most geologically active moon in the Solar System, it's basically a giant ball of sulfur, with over 400 active volcanoes which can spit plumes of gas and ash over 100 miles high, and massive lava lakes. Despite those, the average temperature on Io's surface is about -280 degrees Fahrenheit. What little atmosphere it has is sulfur dioxide, and does nothing to stop Jupiter from blasting it with radiation.
- As such, Io is actually a mottled yellow-brown-green in color, not blue as depicted in the cartoon.
