It amazes me sometimes how different opinions can be. I absolutely hated Quadraxis and thought it was one of the weakest bosses in a game already filled with weak bosses.

"Easily the worst" in your opinion (which is quite questionable I must say), please.

Prime had my favorite boss of all time, and Corruption had one of my favorites too. The only ones I found somewhat nice in Echoes, and even these were still annoying, were Chykka and Emperor Ing.

First of all, that's your opinion. Just because you didn't find them hard doesn't mean they weren't good - difficulty and quality really don't go together very often. I agree that Flaahgra and Thardus were far from great bosses, and the Hive Totem was one of the shittiest and most annoying battles in Metroid history... but I never said the whole game was filled with great bosses. I said it had my favorite boss ever, not my favorite roster of bosses. That said, I liked all 3 final bosses quite a lot.

Secondly... please don't spoil the game for those who haven't played it.

Your post ended here for all I care. I hate this whole "spoiler for a 600 year old whatever" argument. It's stupid. Just because something's old, it doesn't mean everyone knows about it. Not all games have been played by everyone because they're old.

I beat Ocarina of Time for the first time in 2012 and was surprised by Sheik at the end. I beat Super Metroid for the first time in 2014 and was surprised by the turn of the events right at the end. I beat Star Fox 64 for the first time in 2013 and was surprised by the powerful and emotional ending. For these and lots of other surprising moments I've had in gaming, I'm thankful I somehow managed to not get spoiled.

You're not going into crazy massive spoiler territory here, but it's enough that it could detract from someone who hasn't played it. The game does have a story and because pretty much all of it revolves around the last few bosses you encounter in the game, it's enough to bother me about this.

Again, you're only looking at challenge here (no wonder Echoes is your favorite game). A boss doesn't have to be either hard to defeat nor hard to figure out how to to be good. In fact, I would say that the more "sophisticated puzzle"-like a boss is, the worse it is. Bosses aren't supposed to be puzzles, they're supposed to be BATTLES. I'd take an easy to figure out weakness, but hard to beat boss any day every day, and that's why the final boss in Metroid Prime is my favorite... and it's also why the final boss in Prime 2 (I mean the actual final boss) annoyed me so much.

Quadraxis might have been unique and creative, but that didn't do anything to me. I didn't find the battle engaging nor fun, and if a boss isn't either (or ideally, both) of those, I won't remember it as anything special.

Maybe it was easy, but it was frustrating as shit and very, VERY poorly designed.

I say that pretty much because when you scan it, the game says "absorb its attacks with your Charge Beam and unleash them back" or something like that. So what do I, as the player, try to do? Well I try to absorb its attacks, of course.

And then I just can't. Instead of absorbing the attacks, I get hit by them. And there goes the timer.

I can't tell you how many times I tried absorbing those things and it never worked, because 80% of the time the boss was using the UNabsorbable (is this even a word?) attack that the game never implied existed in the first place. This, with the ridiculously urgent music and timer running down at the bottom, being the final moment in a very long sequence and battle, naturally got me desperate and frustrated, which led to me just giving up because there was nothing I could do. Which in turn led to me losing like THIRTY FUCKING MINUTES of progress.

You know, this is the kind of stuff I hate Echoes for. It reminds me of the one other time I died on this game, which was to some random monsters in the water (you know, those that bite you and you have to shoot them in the mouth, only it was the Dark version of them). I got stuck on that room, frustrated, because I had to kill them to get through and they just wouldn't die - I would shoot right at their mouth, try to dodge, inevitably fail and get hit by a 40 damage attack over and over... only to realize my shots somehow weren't just hitting the right spot. Ugh. I guess you could say this is a problem with the trilogy version since the original would lock on perfectly, but still, that was ridiculous.

But we're getting insanely off-topic here, so excuse me.

You really do love going as far off-topic as possible, don't you? And I just always inevitable follow you around.. sigh.

I already beat the game, I know what to do. That said, how the hell am I supposed to know not to lock on to her? I mean, locking on is pretty much the quintessential thing you do everytime you meet an enemy, let alone a boss. Of course I would lock on and stay locked on. This is the kind of stuff the game should have told me in the scan... or rather, not even require in the first place, because requiring you to unlock your aim is stupid.

If her missiles looked like missiles, I wouldn't have even tried to absorb them, but the game tells me to absorb her "Phazon-based attack", and her missile is indeed a "Phazon missile" and it does indeed look like phazon stuff. I couldn't even tell they looked like missiles with the amount of blue glow they had.

I won't even bother with the rest of your post as it's pretty much all like "I beat this game and thought it was easy, git gud scrub".
