Bucky O'Hare

Bucky O'Hare was released for the Nintendo Entertainment System in 1992, which required Bucky to rescue each of his crew members (except Bruiser, who is not featured in the game) on a series of planets. As each character was rescued, the player gained the ability to switch between them and Bucky on the fly to deal with different problems. Immediately after regaining his entire crew, they are once again captured and imprisoned on the Toad mother ship. Bucky and Blinky, sharing the same cell, break out and must rescue the remaining members. Afterwards, you continue through the monstrous ship. The gameplay and level design very closely resemble that of Capcom's Mega Man series.
