Time capsule
1 
My ego is so big that among the things I would put in a time capsule would be at least one of my created pieces. The Dreamer is one of my newest creations. It is perhaps not the most complex or even most beautiful of my works. But I really like it. Also this piece might give future generations a bit of a scare. I would like to see their faces after they would see it.
So far I don't have this but I intend to get it in the future. I think that once I start collecting manga I will definitely pick Berserk. For me Berserk is one of the greatest works of fiction ever created. I would like to introduce future generations to this epic story. Such marvelous work of art should never be forgotten.
3 Fake treasure map.
I would draw a map that promises a few milion worth tresure. But it would not lead anywhere. I would do this as my final prank for people of the future.
Report to home station.
I can confirm that earth is a perfect planet for our invasion. Local life forms are very primitive. They still inhabit only one planet. They still are not able to use cloning or time travel. Their military is also weak. Their military is also weak. But most importantly earthlings are very divided. Their leaders are mostly incompetent and selfish. The irony is that many of the earthlings would probably see our invasion as a blessing. Their current lives are so miserable that they would think that we are their saviors. Defeating earth's leaders and their armies will be easy. Especially now because they are once again fighting each other. Even though earthlings are very primitive but the planet itself is very beautiful and rich. It has a great variety of plants and animals. Until now local barbarians still not managed to destroy everything. Also while local primitives are not very advanced they did create some impressive art and architecture. In conclusion of this report- now is perfect time to invade earth.
