YMMV: Mega Man 4

  • Awesome Music / Ear Worm: Plenty. This is a Capcom game, after all.
  • Breather Boss: Toad Man, since he can be looped into an infinite where he does nothing but jump. Pharaoh Man too if you use his weakness (he becomes a sitting duck), and Bright Man if you know how to stop him from using Flash Stopper.
  • Ensemble Dark Horse: Skull Man and Pharaoh Man have quite a few fans, thanks to their character designs and exellent stage music. Pharaoh Man got a massive boost thanks to his Western Animation counterpart.
    • Dr. Cossack and Kalinka have also gained quite a fanbase despite their limited appearances in the series.
  • Fanon: Fans love taking Dr. Cossack's Glorious Mother Russia aspects and cranking them Up to Eleven. The fact that his Supervillain Lair resembles features of the Saint Basil's Cathedral doesn't help.
  • Fanon Discontinuity: Some hardcore fans like to consider Mega Man 3 the true final game of the Mega Man Classic timeline, preferring to assume Dr. Wily died at the end of 3 and ignoring everything from 4 onwards. (some less hardcore fans like to consider the same of Mega Man 6, and ignore everything from Mega Man 7 onwards).
  • Good Bad Bugs: When one uses the Flash Stopper, certain enemies that would normally be shielded from the Mega Buster lose that invulnerability. This means one can shoot Shield Attackers in their shielded side and destroy Skeleton Joes that are otherwise impervious to anything more than a charged Mega Buster/Pharaoh Shot attack.
    • When fighting Tako Trash in Wily Castle 2, one can use the Drill Bomb to destroy the boss's hitboxes, allowing Mega Man to walk behind it without taking Collision Damage, shoot it from behind, and be completely safe from its fireballs and bombs.
  • It Was His Sled: It's almost common knowledge by now that Dr. Cossack isn't the real villain.
  • Most Annoying Sound: The sound of a health bar filling up is the loudest it's ever been in the series, to the point that it drowns out the music more or less entirely. This naturally makes the usual Boss Rush near the end of the game a lot more obnoxious in the audio department than in the other games. It doesn't help that it takes longer for the health bar to fill up than in the past games as well.
  • Spoiled by the Format: Officially, the Robot Masters in this group are part of the DWN series. Whatever could that indicate about Wily's involvement in this game?note 
  • That One Boss: Pharoah Man if you don't have his weakness (you do and he's a pushover), as he's really fast and hits hard.
    • Also Bright Man, who can stun and then jump on you for massive crash damage. Unless you know he only uses Flash Stopper at specific HP intervals, then you can shoot him with one uncharged shot and take him down with nothing but charged shots or Rain Flush in relative safety.
    • Then there's Ring Man, who can cause huge crash damage and counterattack if you shoot him on the ground.
    • Wily Machine 4, if you don't know that you can detonate the Drill Bomb in mid-flight. This can lead to having to resort to Outside The Box Tactics such as trying wire, Rush Jet, or Rush Coil in an attempt to hit that just-out-of-reach weak spot.
  • That One Level: The end of Bright Man's stage is very difficult and frustrating. You have to jump on moving platforms while dodging the projectiles of the Lightbulb bots. Oh, and don't shoot said bots, as they will black out the screen.
