[opening theme music playing]
[humming]
[chuckles]
-All right! -Yeah!
Sweet landing!
Ready to explore nature?
Yeah, dude. Nature is the best!
[squawking]
Look, a weird bird!
Check out this stinky plant! [retches]
Whoa, the entrance to an underground crypt.
-[thunderclap] -[spooky music playing]
Ooh! [chuckles]
See? This is the best part of exploring nature.
Going inside hidden ruins.
Thanks, nature!
-Bye! -[both screaming]
-[thuds] -[both groan]
-Yeah! -Let's do this!
[both chuckling]
I got a jeweled sword
and a crazy looking ring!
Nice. I'm gonna see what's over there.
Bronze bear.
Silver cup.
Weird rock.
[gasps]
[dramatic music playing]
[chuckles]
I bet there's some cool stuff in there.
Oh, but it looks pretty heavy...
[scoffs] No problem.
I've been workin' out.
[inhales deeply]
[effort grunt]
[breathing heavily]
[straining]
Let me help.
[rumbling]
[Mongor] Fools!
You have released the mighty Mongor!
Tremble and despair,
for the more you fear me,
the stronger I become!
[angry goat war cry]
[blows]
Yeah, you're not scary at all though.
You're so small.
Maybe go pick on a beetle or an ant.
Cut it out!
I may be small now,
but I feed on fear!
Fear me
so I can become larger!
[bleats angrily]
[scoffs] Not gonna happen, buddy.
Let's go home. I'm hungry.
Later, goaty.
Oh, man,
I wonder what Tygra's making for dessert tonight!
Ignore me now,
but soon I will be big enough
to crush all of Third Earth
under my mighty hoof!
[dramatic instrumental music]
[bleats]
Take that! Fearful feline.
[stomping]
Hey, you...
Knock it off!
[laughs]
I destroyed your diorama.
Aren't you scared?
No, I'm annoyed.
I was trying to figure out where to put the pool.
You... outta here!
Never!
Hey! [grunts]
WilyKit! WilyKat!
Do you know anything about this goat demon?
Oh, yeah, that's Mongor.
We released him from a tomb,
and now he's following us around.
-He's a drag. -What?
We do not keep demons in this house.
Get rid of him.
-Can we do it after this show? -[meows]
-Hey! -[chomps]
Now! Or no dessert.
[both groan]
[WilyKit] Okay, time to go, Mongor.
[Mongor gasps]
All right, see ya later.
[Mongor] Wait, no! No, please!
I'm a fear demon.
I need to scare someone
or I'll have to go back to my tomb
and be all alone again.
I hate being alone.
It's so...lonely.
Wait, if we help you scare someone,
you'll go away?
I promise I'll go away...
[maliciously] To destroy Third Earth!
[cackles]
Yeah, cool. Sounds good to me.
Yeah. As long as we get dessert.
[both] Time to help a demon!
[vocalizing]
I'm playing with my toys.
-[vocalizing continues] -Okay, Mongor,
you go hide with Lion-O's toys,
and when he turns around,
you come to life and scare him.
Got it.
[grunts]
-[cackles] -[groans]
What's this?
Mr. Goat-tholemew
is challenging Princess Pony for the throne?
How dare you challenge me beardy goat man?
-Neigh... -Ahhh!
[groaning] Must. Use.
Ow. Demon powers.
[Lion-O] Don't worry, your highness,
Prince Fuzzbie has your back.
Ahhh! Get off me.
I'm Mongor.
[groaning] Ahhh! Ow!
All right. It's training time.
Okay, Mongor, you can do this.
When she runs by,
just jump out and yell really loud.
Got it. [effort grunt]
Ready, Snarf?
[meows]
-[inhales deeply] -[whistles]
[meows]
Yup, here she comes.
Behold! The Mighty Mon...
-Oh, wait, what? -Try again.
[Mongor] Hmm. Let's see.
Now! Behold... Hey!
Behold! Nope...
Behold! Ugh, come on!
No matter.
I'll just stay in place.
Because I am the-- [groans]
[moans] Wait, no!
[grunting]
[coughs]
[voice shaking] That was a bad idea.
[humming]
Okay, only one ThunderCat left,
but this one's easy.
Panthro's totally scared of bats.
Really? Why?
Ah, everyone needs a thing.
Wait, hold on. What...
What's my thing?
Anyway, put these on, and he'll totally lose it.
-It'll be great. -Okay.
Fear me.
For I am a bat!
Huh? [gasps]
[maliciously] Yes, yes.
Your fear grows.
[breathing heavily]
[softly] Okay, Panthro,
you've practiced this.
Deep breaths.
It's just one bat, it can't hurt you.
Uh, what's happening?
[sighs]
That's better. Welp, back to work.
[yelling] You picked a real lousy time
for some personal growth, you big jerk!
Heh?
[sobbing] I couldn't scare even one of them.
I'm the worst fear demon ever.
Yeah, pretty much.
I guess I'm stuck this way.
I'm just gonna go back to my tomb
and wallow in my loneliness
for the rest of eternity.
Whoa, whoa, whoa, whoa!
What just happened?
I don't know.
I was just thinking about
how I'm going to be all alone.
Wait a minute. Are you afraid
of being alone with yourself?
Of course I am.
Being alone is horrible.
Hold on.
I've got an idea.
You're still too small.
You're going to have to go back
to your dumb old crypt.
No. I don't wanna go back.
Ooh! Oh, yeah.
Um, that place is so dusty and sad,
I bet nobody else finds it
for a thousand years.
[sobs] Don't say that.
Yeah, it's too bad.
Everyone else in the world
gets to play video games and eat dessert,
but you're just gonna cry in the dark forever.
[sobbing] It's not fair.
I don't wanna be
tiny and alone forever.
[both] Hey, Mongor!
Yeah?
Hey!
We did it!
Thanks for all your help, guys.
You're the best!
[both] High five.
You fools.
Now I have the strength
to destroy you all.
Behold the power of fear.
-[both crying] -Let go, you big jerk!
[cackling]
-[whimpers] -[groans]
-[laughs wickedly] -[both] Ahhh!
[both screaming]
Hey! What's going on here?
The furniture.
Tygra told us to help out a tiny demon.
Then he got bigger
and he's wrecking the place.
-That's not what I-- -Uh-uh.
Tygra...
we'll talk about you helping demons later.
Right now, we have to stop him
before he gets any bigger.
ThunderCats... Ho!
Take that.
Nice try, pitiful mortal.
[angry goat war cry]
I've got you, Lion-O.
[groans]
Hey, Mongor,
ever heard of a bolo whip?
No one's heard of a bolo whip.
[snarling]
[groans]
Nice job, Snarf.
Nowhere to go now, Mongor.
[laughs wickedly]
Get over here!
Oh, no.
Fear me now, Tygra?
Tygra! Quit helping the fear demon.
I'm not trying to help him.
I just got scared!
-[laughs maliciously] -Toots.
[all groaning]
Uh-oh.
I can't help it either.
[laughs evilly]
Isn't it scary
how you can't control your fear?
That's right,
you all fear Mongor!
Hey, you!
Your scrawny goat legs
don't scare me.
[whimpers]
Okay, I'm a little scared.
Thanks, buddy.
[Cheetara] He's going to squish us all. Run!
Oh, man, grab the spaceboards!
[both screaming]
[laughs wickedly]
[tense music playing]
Fear! Smash, smash, smash.
[laughs]
So long, puny ThunderCats.
Off to crush the world.
[laughs]
And this is why we don't keep demons
in the house, Tygra.
What are we supposed to do now?
Mongor's just gonna keep getting
bigger and bigger forever.
-Wait, that's it! -[clicks fingers]
Come on, WilyKat!
Wait, what's the plan?
Tygra! Stop helping the demon
by slowing everyone down
with dumb questions.
I'm not helping him.
[dramatic music playing]
[WilyKit] Ready? Jump!
[cackling]
I'm finally big enough
to destroy Third Earth.
[cackles]
All right, here we go.
Hey, Mongor,
what if you're too big?
What a weird thought.
Where was I?
Ah.
Soon, fear will envelop the land!
Who's gonna be friends with you now, Mongor?
I feel so lonely all of a sudden.
Oh, no.
No one else is this big.
You're the only one.
Maybe I don't want to be this big.
You're gonna be alone forever.
Oh, no, what have I done?
I hope Kit and Kat aren't on there.
I don't want to grow anymore.
[breathing heavily]
Stop freaking out, Mongor,
it's fine.
But what if I can't stop growing?
It's working.
Pretty soon he'll be so big,
he'll fall off the planet.
Wait a minute.
We wanna stay on the planet.
Let's go!
[both grunting and panting]
[both scream]
[groans]
-Man, this guy is hairy -Yep.
Good thing he's got strong follicles.
[gasps] He's getting bigger!
-[both groan] -Right in the epidermis.
Come on, Kit, let's go.
[bleating fearfully]
Oh, no, he's still getting bigger.
[both scream]
Where the heck are we?
It's the endoplasmic reticulum.
Quick, hop on a vesicle.
[excitedly] Woo-hoo! Yeah!
All right. This is awesome!
Hey, uh, Kat,
I think I figured out what your thing is.
What? Really?
[growling]
[screams]
That's not my thing.
Everybody loves cellular biology.
[both gasping]
Oh, we're going subatomic.
[both screaming]
-[WilyKit] Hey, we're out! -[WilyKat] All right!
[both laughing]
[both] Woo-hoo!
What did you guys do?
What's happening to Mongor?
[growling]
Help!
I'm too big.
[whimpering]
[screaming] Oh... no...
[soft instrumental music playing]
Oh, neat.
He turned into a constellation.
Wait, so now he's an ever-growing mass
floating through space?
Whatever, Tygra!
You didn't say how to get rid of him,
you just said get rid of him.
Don't worry,
it's pretty cool being stars.
Thanks, Kittens.
Now I'll never be alone.
[Tygra] Oh. Well, that's nice.
[wickedly] Because I'll be watching over all of you.
Always!
Oh, wait, that... that's bad.
[bleats]
