@Dreamsicle  
not to mention lord tirek was defeated by multicolored talking ponies, while frieza had to make goku unlock an ancient legend to beat him. this fight for tirek was over before it even started.

@Trahzo  
You’re only supposed to write one person.

@Trahzo  
Didn’t Freeza came before Mewtwo? Dragonball began in the late 80’s.

Frieza:  
Sorry no magic here,  
I’ll fill you with fear.  
I stomp planets under my heel you runt  
Anc you lost to a bunch of pony cunts!
 
Tirek:  
How cute, a Mewtwo ripoff,  
Why don’t you let me tear that jaw off?!  
I’m the OG bad guy,  
Comparing me to you is like comparing a swatter to a fly  
Believe that I shall rise again,  
but I wont be bested by someone who was beaten by Mr.Satan!
 
Then Frieza goes golden!  
Frieza:  
Say hello to my new form,  
I’m unleashing a storm!  
You can’t beat me you old man  
My power level is so strong, nobody can stand!  
You were betrayed by your own brother,  
and I bet by extension, your mother!
 
Tirek:  
Yeah, I’ll take that pizza to go,  
Thanks for finally coming out of the closet you golden hoe!  
I don’t give a crap about my family,  
Even your ancestor was killed by Goku’s daddy!  
You really wanna mess with the true devil here?  
At least I defeated my hero you radiating queer!

@Evil Emperor Proteus  
Well gen use that for Freeza’s lyrics.

@Whiteeyes  
Tirek was beaten by a small dog-sized Pony who is the equivalent of a teenager after someone else gave Tirek lots of power.
 
Freeza runs a space empire and destroys worlds, Tirek runs nothing.

@darklord99100  
Tirek  
So look what the space cast dragged in,  
A guy way too dumb o ever win.  
So you call yourself Lord Freeza?  
I wouldn’t even call you to deliver my pizza!  
You ran a space empire full of flunkies,  
But in the end got taken down by two different monkeys.  
You chopped yourself into little prices, got saved by Goku  
But nobody’s here to save you when I smoke you!  
I’m gonna lay down the vocal smack now I mean it  
And it ain’t gonna take me no “five minute”.

I’ve got nothing.  

@Evil Emperor Proteus  
FREEZA FREEZA FREEZA!

Freeza wins. Like, by a lot. On account of being FREEZA.

EPIC RAP BATTLES OF ANIMATIOOOON!  
LORD TIREK  
VS  
LORD FRIEZAAAA!  
BEGIN!

Tirek almost conquered Equestria twice. Meanwhile Frieza successfully conquered/destroyed several planets, and nearly wiped out an entire race or two.
