Henkei! Henkei! (comic)

Unlike the Hasbro version of this line, the toys in the Henkei! Henkei! line comes with several mini-comics, usually promoting the toys they are sold with.

Volume 1
In the 21st Century, Megatron attacks Tokyo, planning to steal its energy and enslave the humans. Then the Autobots arrive to stop the Decepticons, saying they will always find the Decepticons and stop them thanks to the humans' information lines. Starscream is taken out by Bumblebee and Grimlock, while Megatron fights Optimus Prime. The Decepticons then retreat, and the humans thank the Autobots.

Volume 2
Astrotrain is in train mode attempting to derail a train at Shinjuku Station until Mirage and Grimlock show up. Astrotrain transforms to space shuttle mode to escape from Mirage, and then transforms again, this time into his robot mode. While Optimus Prime and Bumblebee attempt to guard the citizens from Astrotrain, it is revealed that the attack is all part of a Decepticon plan. While Astrotrain creates a distraction, Megatron and the other Decepticons are slowly collecting energon. Megatron is then attacked by a new Autobot warrior...
