Morpha is super simple. I'm going to have to make a video beating him to show everyone the easy way to beat him.
I'd have to say the hardest boss is Bongo Bongo (and I'm one of those people who could beat all of these bosses in my sleep, and all things considered, he's the hardest) but Ghoma is the most annoying. It's super annoying because it's super easy and I would have liked more of a challenge on my first boss.
Phantom Ganon was annoying. What was his problem really? To hide in a couple of paintings (such a cowardly behaviour). Yet so impatient and he could not stay there for a large amount of time it seemed! I must admit I had some problems wit him/it and that is probably the main reason for why I consider him so annoying. He was a good boss though, what if things went too smooth? We want a bit of a challenge do not we? :yes:
Definitely Phantom Ganon or Morpha. Phantom Ganon was really tricky for me, especially as a child, and it always took me around five tries to actually defeat him. Morpha I luckily beat on the first try, but with one heart left because I was always thrown around the room too much. That and it's just downright annoying.
Volvagia, hands down. I kept on getting hit by her constantly. I've beaten OoT so many times, which SHOULD mean I'm experienced, but I still encounter difficulty with Volvagia. I still have to be revived by a bottled fairy constantly. Oh, and not to mention her battle sequences and phases are the pits...
Bongo Bongo was an absolute pain for me, I had no idea what I was doing first time I went up against him and ran out if arrows pretty much straight away. Even when I knew what I was doing he was still difficult.
The hardest to beat for me is Volvagia. Every boss needs a different strategy, and sometimes, my mind just doesn't work that way, but that's exactly what I love about Ocarina of Time.
What Navi says: "It's the Boss of the Fire Temple, revived by the Evil King. I don't know its weak point..."
So, Navi is just about the least helpful thing you have here, aside from your Kid Link items, but those don't matter anyways. Due to the fact that Navi gives you nothing helpful at all, you need to figure this one out for yourself. I haven't played OoT in 2 or 3 years, and I'll admit, I panicked a little. Volvagia's first phase is absolutely easy. It just pops up in a hole an you pound the crap out of it with your hammer. Good. But the second phase is also fairly self-explanatory, it flies around the room and you shoot it. Harder, but still possible. I freaked out in the third phase. The third phase is where Volvagia goes very high into the air and hurls rocks at you from above. I had no idea what to do, so I just ran around and around until the rocks stopped. Thankfully, they did. After one or two times going through all three phases, I got a little more calm and comfortable, it was really easy.
