The Top Ten
If you get duster first he won't be that hard
This boss is right after you regain duster again, and if you are playing through the intended way then he will be 5 levels behind Lucas, Kumatora, and Boney. and don't forget he has 3000 HP and starts healing by 500 when he is almost dead. I had to grind for half an hour just to get my party at a high enough level to beat him, and I have seen streamers take hours to finish him. - JTLH101
I only beat him because of luck
PSI Flash Ω, PSI Shield Beta, Dimondizing bites, Mortal blows like crazy, this guy should be number 1. He's all bad news.
Sometimes this boss is easy, sometimes it is not. this boss is extremely hard because the difficulty of him will change depending on how smartly you play until up to him (by that I mean stat wise, the game does not literally make him harder.). my second run through the game I abused save states throughout the fight and finished with only Paula still alive. every lets play I see of earthbound the lper says that he is a tough boss. - JTLH101
This boss is stupidly easy. I beat him on my first playthrough without taking a single hit
This boss is especially hard for those on their first playthrough. the only reason it is so hard because it has very high damage attacks, even though he misses a lot he can demolish your whole party in a few hits. one lets player even played the boss after poo left his party again and only had jeff, ness, and paula for the fight. - JTLH101
You are seriously forced to grind for money and buy pencil rockets and the latest bat (couldn't find the name, sorry) for lucas. there is not much buffs or debuffs you can use on him making the toughest boss in the early part of the game. - JTLH101
Mr. Genetor is hard, but not so hard that you will have to grind for him. he will reflect physical attacks when he is not charging making Duster and Boney useless the whole time, but even when they are bashing the crap out of Mr. Genetor he will be healing himself anyways, keeping him high on health the whole time. - JTLH101
There are two ways to go about this boss, you can wait and heal until he runs out of PP, or just go right into the kill, both are hard and tricky to pull off. - JTLH101
I never had trouble in many of the Earthbound bosses, but I had a lot of trouble with Ness’s Nightmare. I only won cause of luck. It’s really hard. He spams PK rocking’ Omega which deals a lot of damage. Also remember that the only person who can battle this boss is Ness, so there’s no team members to assist you.
He's the final boss! Of course he's a hard boss!
This one is simple, if paula is dead your screwed and you have to try again. - JTLH101
True, but I managed to beat him, anyway.
This guy starts with a shield beta making it so that your only hope of defeating him/her/it/they (i don't know, it's a robot) is by letting jeff blast some bottle rockets at its face, while at the same time the other three do not do anything to Starman deluxe - JTLH101
These guys have a lot of health and a lot of good attacks. all you can do is spam pk ground and love hopelessly trying to defeat them. - JTLH101
This guy is nuts.
Why so low on the list!
This boss was so hard that I gave up on the game the first time I tried to beat him. its pretty tricky knowing how close to the start it is. - JTLH101
Use PK FLASH B and he is dead
This is always so painful. While it isn't hard to beat it is so hard to lose EVE
First phase is pretty easy. But the second half of the battle is where he uses strong PK attacks. Don't forget those luxury bananas he has...
Hardest boss in the whole game! Took me 10-20 hours to beat.
