I, Doraemon, Will Become Ruler of the Universe!

Many years later, Da Xiong had finally grown up and no longer needed Doraemon's help. Doraemon, too, had grown old and worn out.

I've worked for the Nobi family all these years. I suppose I've repaid the kindness you showed me back then.

I don't want to be a childcare robot anymore. I want to live my own life with dignity, just once!

Doraemon Legion, move out! Let's carve out a place of our own in this universe!

Watch the Doraemon God of War charge into battle!

(Comedy, dumb fun, don't overthink it. You can treat it as an infinite-world story if you like.)
