Believe it or not, that artwork was an improvement
That was the American cover for Mega Man 1. This is the European cover.
The European cover for Mega Man 1 was epic:
So, the Dragon is from one of the Wily stages. The fish is from Bubble Man’s stage. The castle on top of the hill is Wily’s base.
But what the hell is that face to the right of Mega Man’s shoulder?

They paid Soriyama $100,000,000 to paint this.
So were the artists of those first 2 games just not aware of the game? Were they just given a vague direction of what to draw?
