Everybody talks about “Nintendo Hard” bosses, but let us not forget the many other classic bosses of the NES era:

• The boss that you have to hit it 128 times
  
  
• The boss that makes you sit through a solid minute of invulnerable bullshit, then exposes its weak point for two seconds
  
  
• The boss with the badass-looking attack that’s actually totally nonthreatening because it doesn’t reach the corners of the room
  
  
• The boss that rips your face off within seconds the first couple of times you fight it, then you realise that it just has a really obtuse pattern and never get hit again
  
  
• The boss that doesn’t flash when you hit it, so you can’t tell whether you’re damaging it or not
  
  
• The boss that performs a frame-perfect jump every time you press the shoot button, and that’s all it does
  
  
• The boss that was supposed to be hard, but its AI is bugged so that it just spins in circles if you stand on the left side of the room
  
  
• The boss whose special attack crashes the NES that slipped through QA because none of the playtesters ever got that far
  
  
• The boss that runs back and forth
