Marvel Future Avengers - The Great Kaiju Showdown

The kaiju properly introduce themselves to the Avengers, explaining that Kei unexpectedly gained the power to bring his drawings to life years ago, forcing him to live in hiding due to others misunderstanding his kaiju. The Avengers apologize for their misjudgment, and decide to focus on the evil kaiju, which are found to be of alien origin. The alien kaiju attack a nearby power plant. The Avengers leave to stop them, but Kei and his kaiju insist on helping. The two groups work together to take down the aliens, only for their leader, the Leviathan, to arrive and absorb the collected energy into itself. To prove kaiju can be good, Kei's kaiju battle the Leviathan alone, but neither they nor the Avengers can defeat it. Inspired by Makoto, Kei combines all his kaiju into a new beast, Smasher, that shares all their powers. Smasher overpowers the Leviathan, and Iron Man strikes its weak spot, destroying it. In the aftermath, Stark gives Kei and his kaiju a private island to live in peace.
