Tokyo Tower

Tokyo Tower (東京タワー Tōkyō Tawā) is an iconic structure located in Tokyo, Japan. It is the second tallest human-made structure in the country, beaten only by the Tokyo Skytree, and it serves as a communications and observation tower.

The Autobots used Tokyo Tower as an antenna to send Kremzeek to the Decepticons' energy magnet. Tokyo Tower also was one of the first monuments scheduled to be treated with corrostop. Whether it ever was coated is unknown.

X-Brawn drove up the not-Tokyo Tower to get a better view of the city and with that Predacon activity. X-Brawn was not pleased the tower's stairway was not built with cars in mind.

Some time later, X-Brawn came back down to steal an energy bomb from the Predacons, but he accidentally activated it. In order to limit the damage it could do to the city, Prowl suggested he'd take it to the highest structure he could think of. X-Brawn's thoughts immediately went to the not-Tokyo Tower, which this time he swung and towed himself to the top of, closely followed by Sky-Byte who wanted the bomb to power up the Megastar. The tower was not high enough to let the bomb detonate safely though, but Optimus Prime had a plan. He ordered X-Brawn to throw it as high as he could and from the ground, Optimus used his water cannon to send both the bomb and Sky-Byte into space.
