YMMV / Mega Man 4

  • Awesome Music: 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 (though he's still more challenging than the former two).
  • Contested Sequel: While few will call Mega Man 4 a bad game, when it's predecessors are considered the best games in the series (and often the best games on the NES) it can't help but fall into this territory.
  • Ensemble Darkhorse:
  • 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 classic Mega Man series, 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).
  • Game Breaker: This game's charged Mega Buster has widely been accused of being overpowered, for doing nearly as much damage to a boss as their weakness. While this was likely done in response to the previous game, where taking on a Robot Master without their weakness tended to become a brutal slog where you had to chip away each and every one of their hitpoints while they could easily kill you with about 4 or 5 hits, half of the fanbase didn't actually have a problem with that, and the other half thought this game's solution went too far in the opposite direction. Aside from the Game Boy Mega Man III, this version of the Mega Buster would never appear again in the series, with 5 and 6 causing you to lose your charged energy when you get hit, 7 and 8 making the charged shot less powerful, and then 9 just doing away with it altogether.
  • 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.
  • Scrappy Weapon: While the other Special Weapons are all useful in some manner, the Skull Barrier is pretty crap since it vanishes after being shot/striking an enemy once, making it useless as a shield. Even worse, the Robot Master it's strongest against, Dive Man, requires you to be close to him in order to hit him with it. And he has an attack that lets him move really fast. And touching him knocks off a large chunk of your health. And the Dust Crusher/Mega Buster are only slightly less damaging but do a better job of eliminating the Dive Missiles. In other words, the Skull Barrier's more trouble to use than it's worth.
  • That One Boss:
    • Pharaoh 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 the 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 100 Watton lightbulb enemies. Oh, and don't shoot said bots, as they will black out the screen.
    • Ring Man's stage can be very difficult due to having numerous instant-death hazards, troubling enemy placement and four Mini Bosses. It's even worse if you're trying to clear it without taking damage and limiting yourself to just the Mega Buster, as Roahm Mythril has done (with an effect on his sanity).
  • They Wasted a Perfectly Good Plot: A rather controversial opinion of some fans who grew a little tired of Dr. Wily and thought having a different villain would actually make sense for the series - though granted, this later on became somewhat of a joke with how Wily is always the villain.
