Chō Wakusei Senki Metafight

Chou-Wakusei Senki: MetaFight (超惑星戦記 メタファイト) is a Platformer 2D/Run and gun video game published by Sunsoft released on 1988 for the NES.

'Blaster Master' Japanese version without the silly froggy intro. There's no story in game it's only explained in the manual:

Instead of taking place on Earth, the game takes place on a planet called Sophia the 3rd in the Epsilon Galaxy, in the year 2052 of the space calendar. The Invem Dark Star Cluster, led by the intergalactic overlord Goez, invades Sophia the 3rd. The Science Academy of Nora, a satellite near Sophia that escaped the invasion, builds a tank, Metal Attacker, to thwart the Invem. A boy named Kane Gardner is chosen to be the pilot of this weapon.
