Mega Man 5

Mega Man 5, known in Japan as Rockman 5: Blues' Trap!? (ロックマン５ ブルースの罠！？), is the fifth game released for the Famicom and NES in the Mega Man series late in the console's life (1992-93). This game also introduced Beat as Mega Man's robotic bird assistant.

Story
From the instruction manual:
 * "Cossack to Mega Man! Cossack to Mega Man! Come in, Mega Man!"


 * "Proto Man has gone wild! City Hall and the spaceport have been totally destroyed and the city's power grid is in shambles. I've never seen destruction on this scale before."


 * "I know you're worried about Dr. Light, but your first duty is to free the city from the grip of Proto Man's robots. I can modify your reactor to give the Mega Buster a little more power, but the rest is up to you. Dr. Light and I had been working on a special project, but it's not finished yet. Maybe if I can get it working, it might give you an edge."


 * "Remember to watch your back Mega Man. Proto Man seems to have become more ruthless than we had thought possible. Good Luck."


 * "Cossack out!"

Proto Man sent several robots under his command to attack the city, and he went to Dr. Light's laboratory to kidnap him, leaving behind his signature yellow scarf behind. Dr. Cossack helps Mega Man in Light's absence by increasing the power of the Mega Buster to stop the robots, and creates the robotic bird Beat to assist him.

When Mega Man confronted Proto Man in his hideout, the real Proto Man showed up and revealed the fake to be a robot called Dark Man, and upon his defeat, Dr. Wily showed up and challenged Mega Man to come and get Dr. Light. Mega Man defeated Wily and freed Light, but when Wily's castle collapsed, Proto Man had to save them from being crushed by the building.
