I'm actually surprised how many people voted for MP2. I suggested that MP2 had the best bosses in the trilogy a long time ago and practically got shat upon.
i've noticed an interesting pattern. the games with most votes have bosses that take some time to kill/have a strat to deal with them, while the games with no votes/almost no votes have bosses that die very fast/have virtually no strat to defeat.
I feel that way about Fusion's bosses, and that has a good number of votes. In fact, one of my favourite bosses is Mother Brain from ZM, and that's pretty simple - missile it to hell.
Metroid Fusion has Nightmare which I feel is one of the most creative bosses in the series, and I liked the SA-X and Omega Metroid encounters. Metroid Prime had the Omega Pirate, Meta Ridley, Thardus and Metroid Prime...all of which were epic and fun encounters. Super has Ridley, Kraid, Phantoon, Draygon and Mother Brain, so I don't need to say anymore on that. I liked the creativity behind most of the Corruption bosses, especially Gandrayda, Helios, Meta Ridley, Aurora Unit 313 and the Defense Droid.
I don't want to bother with quote code, so I'm going to respond to everyone like this.
My first playthrough of MP2 was epic fail. Here's the stupid things I did (feel free to laugh):
1. I died repeatedly against Alpha Splinter before he was absorbed by a Darkling, because I was trying to sidestep-dodge instead of just running in circles (if you sidestep-dodge, he will always hit you. This still doesn't make sense to me, but I know better than to do that now). I actually found him easier to fight when he was in Dark form.
2. I wondered why Grenchlers had so much health, while shooting them with the Light Beam.
3. I wasted a long time and a lot of ammo on Amorbis, because I merely got out of the way when he started inhaling instead of switching to Morph Ball and bombing inside of him.
4. I was killed repeatedly on the last part of the Spider Guardian bossfight, because I did not know you could change the perspective to zoomed-in at first and so I couldn't get the ball to stay at the top of the ramp where the last bomb slot was.
5. I had very limited Light and Dark beam ammo for most of the game because I completely missed that Beam Ammo Expansion at the entrance to the Space Pirate Outpost.
6. On the Quadraxis bossfight, during the last part (in which you're supposed to Boost Ball onto his head and lay a bomb in each slot), I wondered how I was supposed to get him to stop dodging my Morph Ball (I hadn't stunned him).
7. And lastly, the point of everything in this post so far, was my epic fail on the Grapple Guardian bossfight. I can't remember how it went very well; I just remember frequently missing his weak point when given the chance to do damage and spending a long time in the Light Beacons bringing my health back up while he slowly circled me.
Of course, I now realize what I did wrong in each of these situations. My second playthrough (in Trilogy) is going much better, although I'm not very far yet.
Fusion did indeed have some creative boss concepts. Nightmare was definitely the hardest among them.
I picked Prime 1 because I couldn't think of anything inherently wrong with any of the bossfights, and because the Omega Pirate was very cool (another boss I fought the wrong way). Really I could've just as well picked Super, except that some of those bosses just really pissed me off.
Also, I sort of exaggerated the Grapple Guardian fight. It wasn't really an hour, but it was long enough for my controller to become covered in sweat by the end.
We could do a separate poll for which was the best boss of all the games. Anyone else up for that?
With Alpha Splinter, Grenchlers, Amorbis, Spider Guardian, and Quadraxis, I was just being a moron. With that missed Beam Ammo Expansion, I wasn't observant enough to see it. With the Grapple Guardian, as I recall, I was simply too slow and inaccurate, and was having trouble with the targeting system.
1. Super Metroid By far, the atmosphere/soundtrack is perfect for each boss. Crocomire was really cool and of course.. Ridley, i just loved the fight against Ridley in this metroid.
2. Metroid Fusion SA-X is the main reason this has 2nd best bosses IMO. Also one moment was very creepy, when you saw that big figure hovering on the background of sector 5, when it first appeared flying through i was like "WTF WAS THAT?" of course im talking about Nightmare! These 2 bosses were something special in this game.
Prime 2's bosses were not hard. Boost Guardian could be challenging at times but that's it. The others are mostly just repetitive and last far longer than they need to.
1) Fusion: All of them were just really cool. Nightmare was cool too, but is it just me, or did that gravity device that shot lasers at you look like a dick (partially because of its location), and his revealed face look like a scrotum? That's just my perverted mind, sorry. 2) Prime: Parasite Queen was a meh boss, but the music was epic. Flaaghra was cool but so frustrating. Omega Pirate was epic but I died a lot when he just needed one more Super Missile to die because of those bombs he lobbed at you and because for whatevver reason those troopers took of multiple energy tanks very quickly. Meta Ridley, like OP, was epic but annoying at the last part, if you missed a chance to hit his chest at the end, you would have to wait thru all that charging and jumping till you got another chance. MP was pretty easy but so epic. 3) Corruption: They were all cvery cool but the final boss could've been 1,000,000X more epic. 4) Echoes: The DS fights were epic, Quadraxis was pretty annoying for me tho.
Metroid Prime had tough, fun opponents. Metroid Prime 2 had not only just bosses, but sections of bosses like the guardians that used that power-up against you. Fun and cool. Not really to Corruption. :|
