(Undefeatable from 'Sonic Frontiers OST')

It's time to face your fears!

We see the camera zoom into Seth, who shoots a smirk before transforming into a lion and letting out a roar.

Cause when you're time has come and gone

I'll be the one to carry on (carry on)

Seth looks over the Magical World, streams of magic far as the eye can see. He looks down at his Keyblade, Zoology, as if he is thinking about something.

And you can throw me to the wolves (throw me to the wolves)

'Cause I am undefeatable

Seth weaves through multiple obstacles at Avengers Campus alongside some Marvel superheroes like Moon Girl, Reptil, Devil Dinosaur, She-Hulk, Moon Knight, Shang Chi, and Miles Morales. Seth takes the form of the following: cheetah, peregrine falcon, antelope, rabbit, bull, crocodile, and velociraptor.

I'm hanging onto the other side

I won't give 'til the end of me

We see Seth dive into a body of water. He takes the form of an average tropical fish as Halle's Ariel and Uma swim past him.

I'm what you get when the stars collide

Now face it, you're just an enemy

Next, Seth takes the form of a Skimwing before rocketing into the skies as a Banshee from 'Avatar,' surveying the land from above. Jake Sulley and his family ride their respective mounts.

You're crossing the line

Then, Seth discovers a Kyber crystal which formats into a lightsaber. He wields one accustomed to Darth Maul's saber structure.

(Whoa, whoa) Now we've run out of time

Seth, as a panther, growls as we see a close up of a Vibranium spear which is coated with purple energy.

(Whoa, whoa) I'll take what is mine

Another close-up of Seth as he swings Zoology at another Keyblade user. The Keyblade Master trains Seth to use his own better on Destiny Island.

(Long chorus)

We see Seth wielding his Keyblade, throwing spells like Firaga, Wateraga, Thundaga, and Blizzaga before he turns into a series of animals: a bear, a tiger, a t-rex, a Smilodon, a Hammerhead Titanothere, a Rancor, a Pteranodon, a dragon, a Jaquin, a Tulkun, a Varadactyl, then an elephant with a loud trumpet.

And when the story ends

It becomes a part of me

Seth stares down a dark kingdom with an ominous atmosphere.

I'll give it what it takes

I'll find another way

I used to never know, but now it's crystal clear

This feeling's just a ghost

Seth closes his eyes as Disney characters he has met along the way flash alongside him, creating a portrait.

It's time to face your fear

'Cause when your time has come and gone

An inky figure lets out a laugh and Seth glows with magic within himself. He closes his eyes as an aura envelops him.

We see Seth point his Keyblade forward, using Spirit Stampede with dozens of spiritual animals. He rides a spiritual horse, holding Zoology forward with a yell.

I'll be the one to carry on (carry on)

And you can throw me to the wolves (throw me to the wolves)

'Cause I am undefeatable

We see Seth pose as an elephant with his Keyblade, letting out a loud trumpet in front of Cinderella's Castle.
