20 HARDEST Sonic Bosses

20 Hardest Sonic Bosses

Welcome to MojoPlays, and today we’re looking at the hardest bosses Sonic and friends have ever had to face.

Mega Octus

“Sonic Mania” (2017)

“Sonic” doesn’t tend to be known for its hard bosses, and even now we’ll start off a little light. You fight Mega Octus at the end of Oil Ocean Zone Act 2, and the primary thing that makes it annoying is the stage’s design. Your platforms periodically lower into the oil below. And when this happens, you have to keep pressing the jump button so you don’t quickly sink. Even when you do have stable ground, Mega Octus sets fire to it with a laser, or tries to catch you off guard with multiple other weapons that pop up all over the screen. Thankfully, when its body is showing, it isn’t too hard to get a lot of hits in.

Mecha Sonic

“Sonic & Knuckles” (1994)

Facing Mecha Sonic as Knuckles during the first phase isn’t so bad. You just have to avoid getting run into when he’s in his spiked ball form. The problem comes when he enters his second phase. Mecha Sonic goes super, and begins zipping all over the arena. The speed can catch you off guard if you aren’t careful, sending rings pouring out of poor Knuckles. Worse is when he starts sending a volley of energy orbs out, which can be tricky to dodge. Although this is the easier of the two Mecha Sonic fights we’ll talk about, it’s still a pain.

Egg King

“Sonic Rush” (2005)

Dr. Eggman obviously has a long lineage as a final boss, each time utilizing some crazy, gargantuan contraption. The Egg King of “Sonic Rush” is no different. Part of what makes this fight tough is how unpredictable the boss can be. It can be hard to read where its arms will slam down, and one of those attacks can one-shot you, regardless of how many rings you have. Then there are those stupid purple lasers Eggman sends out, which give you little safe space to move in. It’s definitely an overwhelming fight. And it doesn’t help that you have to fight it twice, once as Sonic and once as Blaze.

Fang Mech MK-II

“Sonic Superstars” (2023)

We’ll talk about a few bosses that use one-shot attacks, but Fang is one of the more annoying ones. As Trip’s final boss in “Sonic Superstars,” Fang the Hunter comes in a two phase mech fight. It’s another one where the first phase isn’t so bad; Trip flies his ship around firing missiles, emitting lasers, and divebombing, most of which is easy to see coming. But my God…that second phase. Fang’s mech gets a major upgrade in size and power. He can send out a bunch of minions, and his cannons kill you instantly. By far the most irritating tactic is the combination of webs that trap you in place, followed by a one-shot cannon blast. And it isn’t as if this fight is short.

Egg Viper

“Sonic Adventure” (1998)

As the final boss of Sonic’s storyline, Eggman comes with another intimidating machine in Egg Viper. Of his many inventions, the Egg Viper is one of the faster ones, both in its own speed and its attacks. He spends a lot of the opening of the fight, leaping up from below the arena and firing lasers in quick blasts. But he’ll also fire giant, spinning blades that’ll tear the rings right out of you if you aren’t quick enough. Avoiding the attacks requires quick reaction time. At least Eggman has obvious openings for when you can hit him. But once the fight is won, the Egg Viper goes out in a kamikaze divebomb that probably took out its fair share of players.

Egg Saucer

“Sonic Advance 2” (2003)

Here, we have another boss that has a one hit kill attack, no matter how many rings you’ve managed to collect. But the Egg Saucer has its own little twist, to make it tricky in its own way. Whether piloted by Knuckles or Eggman, it constantly rolls forward, forcing you to run after it. But while you’re doing so, and trying to deal damage, the Egg Saucer is trying to wallop you with a gigantic hand. This is the one hit kill, and it can be hard to avoid since it's attached to a stretchy arm. You have to both know when to rush forward, and keep your distance, unless you want to start all over.

Giant Eggman Robo

“Sonic & Knuckles” (1994)

Powered by the Master Emerald, Giant Eggman Robo is one of the more intimidating Eggman mechs of the classic era. Once again, it’s a fight whose first phase isn’t too hard - all you have to do is avoid and destroy the mech’s fingers - and this lures you into a false sense of security before it unleashes all Hell for the second. Eggman begins chasing you, firing bursts of flames and, much worse, a massive blast from the Master Emerald itself, which can be pretty tough to avoid. Start landing those attacks quickly, or else it’s back to the beginning. Even though there’s one more boss right after this, the Final Weapon is a fair bit easier.

The End

“Sonic Frontiers” (2022)

No, we didn’t accidentally put in footage of “Ikaruga,” but we can see why you might think that. To even reach this boss, and unlock the true ending, you have to first set the game to Hard Mode, which should tell you something. But it’ll obviously take a lot of adjustment, going from a 3D platformer to something completely different: an intense, arcadey shoot ‘em up. As The End fires Dark and Light bullets, you can switch your own to destroy them. Unfortunately, it isn’t long before your entire screen is filled with a swarm of gunfire. As the attacks grow more aggressive, it gets harder and harder to destroy or avoid them. Only with a lot of very precise movement and a cool head can you come out on top.

Big Egg

“Sonic Superstars” (2023)

The second of the three final bosses we’ll talk about from “Sonic Superstars,” you can face the Big Egg at the end of the main storyline. Thankfully, it doesn’t have an insta-kill attack like Fang’s mech. But it does have a lot more variety, and still two phases to try and crush you. In the first, you’ll be doing a lot of dodging, whether it be laser walls, electric orbs, or a hail of missiles. In the second, you still need precise reaction time to dodge damage, just now while being relentlessly chased, and with the Big Egg now having doubled the amount of attacks it has.

Perfect Dark Gaia

“Sonic Unleashed” (2008)

“Sonic Unleashed” ends with both the villain and Sonic transforming. But despite the power of Super Sonic, Perfect Dark Gaia is a huge final hurdle to overcome. Part of what makes it a pain is how long and exhausting the fight is, since you fight it directly after its first form. You first have to fly through a dense field of floating boulders. And while there’s plenty of rings to collect, it’s hard to avoid taking damage at such high speeds. Then, while Chip pilots the Gaia Colossus to take on the boss, Sonic works to destroy its shield. That’s easier said than done; you have to take out giant tendrils that only poke out at certain spots, while still keeping an eye on both yours and Chip’s health bars.

Black Dragon

“Sonic Superstars” (2023)

Since you have to beat both the main story mode, Trip’s story mode, and collect all seven Chaos Emeralds across the game, you can expect the true final boss of “Sonic Superstars” to be pretty tough. It’s another Super Sonic fight, with your rings constantly drained as the fight goes on. It’s a long one, too, and the Black Dragon is an absolute beast. It can spawn black holes that instantly kill you, unless you boost out of them. Most of its attacks keep you constantly moving to not take a hit, like groups of huge boulders, giant fireballs, and its own body as it comes barreling across the screen. It’s a long time to keep up a constant defense.

Egg Emperor

“Sonic Heroes” (2004)

As we’ve already seen, Eggman has no shortage of funding for devious devices that give us trouble. And while there are still more to come, the Egg Emperor from “Sonic Heroes” is one of his more irritating machines. The controls don’t respond quick enough to let you react and dodge most of his attacks, and the enemies and turrets can make the fight really annoying. Yes, you can spam the fight by just attacking with a Level Two Flight character, and it doesn’t make the fight any better.

Big Arms

“Sonic the Hedgehog 3” (1994)

Compared to Eggman’s other machines, Big Arm is perhaps the most awkwardly designed. Granted, the first two phases of this final fight shouldn’t be much trouble as they are easy to cheese. But once Big Arms comes out, timing is everything. Eggman is now protected by a pod with two enormous arms and massive spikes decked out on top. Basically, you have a really small window to make your shots, and if you touch even a single pixel of the spikes, say goodbye to most of your rings. And yet, Big Arms isn’t even the hardest of Eggman’s arsenal.

Perfect Chaos

“Sonic Adventure” (1998)

We can understand why the final battle against Chaos in its ultimate form would make for a difficult boss fight. We just weren’t anticipating it to be hard in this way. To defeat Perfect Chaos, you need to reach the monster before your ring count is depleted AND you need to maintain constant speed. Should you reach Chaos at a low speed, you will not be able to damage it, and you will have to endure another phase of the fight. With Chaos harassing you with so many projectiles, this fight is way harder than it should have been.

Imperator Ix

“Sonic Chronicles: The Dark Brotherhood” (2008)

Weren’t expecting to see the weird BioWare RPG on here, were ya? Well, that’s the thing with “Sonic Chronicles” - it pops up when you least expect it. And yes, it does boast some incredibly tough bosses. Imperator Ix, the main villain, serves as a boss character roughly midway into the game and at the very end. Both times, he can be troubling. His attacks are powerful, and the QTE’s required to dodge or even resist damage can be overwhelming. That’s right! This is an RPG on the Nintendo DS that requires more physical reaction than just tapping a button! You need to actually move your fingers and hand and tap the screen in order to properly execute attacks and resist enemy attacks. Better nail down those reactions before reaching these fights!

Metal Sonic

“Sonic the Fighters” (1996)

Fighting Metal Sonic in a 2D platformer is surprisingly not all that difficult. But what about in a 3D fighting game? Well, he turns into a giant freakin’ cheater! Metal Sonic can shoot an unblockable laser beam from his chest, and his barriers are harder to break. Oh, but he can break your barriers without much trouble. Yeah, that’s totally fair. On top of that, just two throws can put you in a critical state, and yes, he will spam it!! He’s not as bad as many other fighting game bosses tend to be, but even for a Sonic spin-off, the cheapness was unreal.

Metal Madness

“Sonic Heroes” (2004)

Look, we have a love for “Sonic Heroes” as much as some of you do, but it’s a real hassle sometimes when the AI winds up killing off one of your teammates because you strayed too far away or they magically fell through the floor. It's even more aggravating when a particular boss fight like Metal Madness requires all three team members in order to progress. There are so many instances where teammates can fall out of the level or just get hit too many times and die. Given that Metal Madness requires you to hit it with each Speed, Flight, and Power character from each team, it’s enough to call it one of the hardest Sonic boss fights.

Sir Lancelot

“Sonic and the Black Knight” (2009)

“Sonic and the Black Knight” is already a cumbersome game to play with its awkward controls and level design. However, the most frustrating battle was when we had to fight Shadow–I mean, Sir Lancelot a second time. The first fight was not much of a hassle since he utilized simple attacks. This time, he’s going full Shad–I mean, Lancelot and is throwing Chaos Spears and Chaos Blasts and Chaos Explosions and Chaos Unleashed and anything that can have Chaos thrown in front of it. Ultimately, you’re forced to just continuously block his attacks and spam your Soul Gauge abilities because anything else is just going to make this more infuriating than it needs to be.

Biolizard

“Sonic Adventure 2” (2001)

This stupid reptile is the bane of any Sonic fan’s existence. What you have here is essentially a water stage. As Shadow, you’re surrounded by water that is textured to look like sand, but one wrong step will send you plummeting to your doom. And in the center is the dreadful Biolizard, a creature that will constantly change its direction of attack, use projectiles to trip you up and cause you to fall in the sand. Oh, and should the Biolizard bite you, you will get launched. Yeah, it’s asinine, and the funny part is that Finalhazard is WAY easier to fight, and that’s the final boss!

Mecha Sonic & Death Egg Robot

“Sonic the Hedgehog 2” (1992)

Death Egg Zone is a migraine for fans of “Sonic 2”, and it’s not even because it’s a back-to-back couple of boss fights. Admittedly, Metal Sonic doesn’t do a lot to make us stumble, and the Egg Robot is a tough but fair fight when considering its simple attacks. No, what makes these two truly hard is the fact that this is the stage. You start with these boss fights, and there are absolutely no rings anywhere to save you! You are forced to do both fights without getting hit ONCE! SEGA, not everyone is a god at video games, ‘kay?
