These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Adaptation Displacement: How many players are aware of the fact that this series started life on the ZX Spectrum, of all platforms — or that this first version was called Eric and the Floaters? Honestly, can you imagine it becoming popular under that name?
It was the 1983 MSX game, released at about the same time, that was called Bomberman.
Judicious use of the Manual Detonator allows you to blast through the game with minimal effort. Just try not to accidentally blow yourself up, okay?
Add in the immunity to your own blasts power-up in the original game and you're a walking angel of flaming death.
Literally, with the Bomb Walk ability. There's a glitch where you can move on top of your own bomb and you can hold down the lay bombs and detonate buttons and you'll be a moving blast area. There's virtually nothing that can touch you. Of course, without the Flame Proof powerup, you die as soon as you let go of the buttons. But with it, you're invincible.
Manual Detonator plus Bomb Kicking Shoes, Bomb Throwing Gloves, or Bomb Punching Gloves, equals ranged remote death.
Super Bomberman gives invulnerability at the start of the level. When you collect Block Pass, and enough Accelerators, you can walk all over the map dropping bombs, taking out at least half the monsters before you become vulnerable. Then, there's indestructible armor that extends the invulnerability period.
You can combine the Remote and Piercing bombs, giving you the ultimate game breaker!
Just Here for Godzilla: Many fans play the series solely for its famous multiplayer matches, and usually ignore the single player mode.
As a result, some versions of the games released in the US actually have their single-player modes taken out. Bomberman Blitz even turned the single-player into a bot-controlled clone of the multi-player.
Altair's overkill-obsessed robot guardian Cerberus in Bomberman 64; Natia in Bomberman HERO; Bomber Elite from Generation, as well as one in some of the other games.
Mantis would also qualify, since she fights you in two different stages. One in her cave and one her web... It's possible to not go down to the web, but good luck if you do. Also, Hades. Dear God, Hades.
The War Beast from the Jetters game was intended to be a fairly challenging Puzzle Boss based on the assumption that you knew that raising the Charabom Youno would give you remote detonation bombs. If you didn't know this, good luck tricking it into swallowing your bombs before they explode. Also, using Level 3 Ceedrun is pretty much the only way to not get hurt by its shockwave attack. The boss also has an attack where it chases after the player at speeds that outrun Bomberman and Max's top running speed. No matter what, you will take damage in this fight.
And before that, Dark Force Bomber is enough to make you want to fling your controller. Don't get us started on Dr. Mechadoc, who is an extremely overdone example of a Puzzle Boss.
