20 Favorite Sonic Boss Battles
Sonic the Hedgehog (Sega Genesis)-Star Light Zone Act 3

In this boss battle, Robotnik drops spiked bombs that explode after an amount of time. In order to defeat Robotnik, you have to use the seesaws to shoot Sonic up to hit Robotnik or send the bombs right back at him.
Sonic the Hedgehog 2 (Sega Genesis)-Aquatic Ruins Act 2

Once you past the lastCheckpoint, you'll go into an area where 2 totem poles come out of the ground. Then Robotnik will appear and go to one side and hit the totem pole. Once hit, the totem pole will shoot an arrow from 1 of 4 random spots into the other totem pole.
You have to dodge and Jump onto the arrows in order to damage Robotnik.
Sonic the Hedgehog 3-Launch Base Zone Act 2

Since this is the last level of Sonic 3, there were 3 bosses.
The first boss has a platform that lifts up to release bombs from the top or the bottom.

The second boss flies up from the left and right and shoots lasers. It has a small spiked ball that floats around Eggman's cockpit so you have to be careful not to be hit.

The third and final boss, which is now known as "Big Arm".
You have to carefully hit Robotnik without hitting the spikes on top or being grabbed by its hands.
Big Arm is a boss in the 3DS version of Sonic Generations.
Sonic & Knuckles-Sky Sanctuary Zone


There are 2 versions of Sky Sanctuary.
The level for Sonic and Tails has them climbing up to the top, while destroying Egg Robos. Mecha Sonic will appear 3 times to fight you.
The first time you fight, he will use the Robotnik's machine used in the Green Hill's boss in Sonic 1. The second time you fight he will use the machine from Emerald Hill in Sonic 2. The third time, he'll fight you himself.
If you're playing as Knuckles you'll face Mecha Sonic twice, but the second time he'll use the Master Emerald to become Super Mecha Sonic. Although he is invincible in this form, he can't maintain it for too long so you have to hit him as soon as he changes back.
Sonic CD-Metal Sonic

The Iconic Boss of Stardust Speedway.
Well, it's actually more of a race than a boss battle.
In order to win, Sonic must reach the goal at the end before Metal Sonic. Behind Sonic and Metal Sonic is Robotnik fires a instant death laser on the track.
Sonic can touch Metal Sonic without taking damage but Metal Sonic can still attack. He can do a boost which allows him to destroy spikes and an electric attack that's similar but causes him to slow down.
I can't wait to play Sonic Generation's version of this level. :D
Sonic Triple Trouble-Metal Sonic + Robotnik


The Atomic Destroyer Bosses.
The level starts out with Rings and a Item monitor, which contains Rocket Boots for Sonic and the High Speed Helitail for Tails. After flying Metal Sonic will show up behind you and ramp into you, turning the item off.
To battle Metal Sonic, you have to Jump as he swoops down from the left and right. When he flies in the middle and starts glowing, you have to wait for 4-5 seconds and then Jump as he boosts across the screen.

After defeating Metal Sonic, you'll hit a Checkpoint, see Nack run away and then face Robotnik. The first machine just bounces around. You can Jump on the top of it to destroy it.

Next, the machine will break and he's flyaround. He'll stop to shoot fire at you.

After hitting him, a part of the machine will break off and explode. Dodge the fire and wait for Robotnik's machine to stop charging to hit it. This part of the machine looks like a Flasher.

Finally, Robotnik will fly over to an area with lasers firing periodically. You have to dodge the lasers and wait for Robotnik to slow down to hit him and finish the battle.
Sonic Adventure-Chaos 6 (Sonic and Knuckles)

After collecting 6 Chaos Emeralds and Froggy, Chaos becomes a giant frog like creature.
Chaos 6 can attack with his tail, try to suck you in like Kirby, create shockwaves by Jumping, and turn into a giant spike tower that shoots needles at you.
You can't attack his head like in his previous forms but you can use Eggman's freezing robots to turn him into ice. Once he's frozen, you can attack him to do damage.
Sonic Adventure 2-King Boom Boo

Probably the most random boss fight in Sonic Adventure 2.
This giant ghost will try to bite you, throw fireballs, and finally breath fire itself.
To defeat it you have to hit the Boo following behind it,holding an Hourglass. The hourglass will open the gates to let sunlight to come in and force King Boom Boo into the ground or wall. Dig into its shadow to make him come out and then punch him.
Sonic Advance-Mecha Knuckles


The Angel Island Boss.
Mecha Knuckles has 2 forms: his pink form where he does the same moves as Knuckles and his grey form where he shoots rockets from his torso. He'll switch forms after getting hit 4 times. Although Jumping on him when he's on the ground works, he's most vulnerable after landing.
Sonic Advance 2-Egg Frog


The Egg Utopia Boss.
All the Sonic Advance 2 bosses have the characters run from left to right as they try to jump and damage Eggman. However,the Egg Frog can hop and run on the ceiling as well as the ground. Fortunately, so can you if you Jump up. If you're on the ground while he's on the ceiling or vice versa, he'll drop a bomb towards you until you switch. Egg Frog will also stop on occasion to ramp into you. You have to jump over its long legs into to damage it.
Sonic Heroes-Robot Storm

In a way, this is more of a trial than a boss fight, since the boss is really waves enemies you have to defeat until you destroy them all.
There's a larger variety of enemies than in the Robot Carnival Boss battle.
Sonic Advance 3-Cyber Track Boss

The Cyber Track boss is unique. Eggman goes left to right while firing blue balls at you. You can hit the balls, which will turn from blue to orange, and bounce them back at Eggman.
In other words, it's like a game of pong. However, the more damage Eggman takes, the more balls he'll shoot at you.
Sonic Rush-Carnival Night Boss

This machine has Eggman up in the air and a weight on the side holding down. The weight can be charged with electricity to shoot down on Sonic and it also has a instant death slam attack that sends 2 soundwaves around the entire field.
When the weight is not charged with electricity, Sonic can hit it. After hitting it, Eggman's cockpit will be lowered and Sonic can do damage.
After hitting the weight, an small enemy robot will roll towards Sonic. If Sonic Jumps onto it, it will send him up into the sky and he can hit Eggman again.
Sonic the Hedgehog 2006-Iblis Phase 3

This choice was hard because I liked some of the bosses, especially when using the different characters. In the end, I liked Silver's telekinesis battles.
Iblis's 3rd and final form will throw fireballs, waves of flame, and smash parts of the ground Silver stands on. It will even try to throw a meteor sized fireball at you.
Silver can take everything it dishes out and throw it back at it. When it gets close, Silver can also Jump onto its head and shoot his energy through it to do massive damage.
You have to defeat it before it can destroy the entire platform.
Sonic and the Secret Rings-Ifrit

A robot with 2 arms that's being powered by the Red World Ring of "Rage". It releases exploding barrels from its shoulders and shoots lasers from its eyes. Also, the battlefield is above a pool of magma.
To defeat it you have to attack 3 sections on one of it's hands. Once you do, 3 parts of the field will sink into the lava and you have to carefully get over to its head.
You have to hit its head 3 times to defeat it.
One secret about this boss is that whenit's time to hit its head, Sonic can Speed Break across the magma.
Sonic Rush Adventure-Ghost Pendulum

The Machine Labyrinth Boss.
The boss swings a small pendulum around in a circle, that has spikes pop out after a certain amount of time. When it's spikeless Sonic can Jump into it and use momentum to knock it up into the air into the robot's core.
It starts out with a small pendulum at first but as its health goes down, 2 ships will fly in to bring in a medium sized pendulum and a big sized pendulum. The smaller the pendulum the easier it is to knock into the robot. The larger the pendulum the more damage it does when knocked into the robot.
Sonic Unleashed (HD)-Egg Dragoon

After clearing Eggmanland in the HD versions, you have to face Egg Dragoon, which is a upgraded version of the robot Eggman pilots in the Intro movie.
You'd think that after beating Eggmanland that this boss would be hard but in fact it's more of a Warm-up.
To beat Egg Dragoon, you have to attack the glowing the green light in its center. After damaging it enough, it will activate a QTE where Sonic jumps onto the machine, Eggman shoots the drill towards him, Sonic dodges the drill, the drill does damage to the robot, and then Sonic tears off several important sections of the machine.
It's pretty hilariously, especially when you do the final QTE, where Sonic grabs Eggman andswings him around before throwing him into the sky.
[spoiler] Egg Dragoon will be a boss in Sonic Generations HD [/spoiler]
Sonic and the Black Knight-Dark Queen

Kind of a easy choice seeing as the other bosses in the game are cheap.
Dark Queen has 2 forms of attacks. Shooting energy balls and swinging swords from one of hermultiple arms.
Her weakness in the eye in her torso. After raising the Soul Gauge, use Soul Surge and slash away.
Sonic the Hedgehog 4:Episode 1-E.G.G. Station Zone

The E.G.G. Station Zone plays similar to Sonic Advance 2's XX level, where you face weaker versions of every boss you've faced until you reach a final new boss.
The final new boss here is a remixed version of the final boss of Sonic 2. In the beginning the robot just flying into the air while avoid the cursor, which is where it will land.
In last resort mode, electricity will protect it from harm and it'll hop around the screen. To take the electricity down, you have to wait for it to fire its arms at you. The arms can be hit in midair or hit 3 times after landing. Sometimes, it'll energy balls from its back.
Before the final blow, Eggman will fly into the air for one final shockwave. If you don't hitEggman after he lands, the platform will be destroyedand you'll fall into a bottomless pit.
Sonic Colors (Wii)-Terminal Velocity Boss

The final boss of the game.
This boss is powered by all of the Color Wisps and uses Frenzy versions of their abilities.
To defeat Eggman, you have to dodge the attacks, and then Home Attack him 4 times. As soon as you land you have to boost into him. This will release the Wisps from the capsules.
After all7 Wisps are released, you can use them to make a unlimited color homing attack.
