Bowser Jr. & King Bowser vs. Lancer & King Spade

Let's give it up for Stark's Rap Battles!
In the left corner, we have, Bowser Jr. and King Bowser
Vs
Lancer and King Spade
Begin!

I'm gonna hop in my Airship and blast these Spades to pieces
Cuz even my Bullet Bills travel faster than your releases
All my cannons and minions are gonna scare you like King Boo
Your dad had to command his in order for them to like you
We're gonna delta-ruin you, you can say we're spittin' fire
You behave not like a king's son, but as a Jevil for hire!
Biting your face off like Susie, better get your bucket ready
And don't rely on your father, with a bond that unsteady
Your maturity at this rate won't make you "son of the year"
I'll fold this deck of cards so that they'll never interfere
Why don't you work on evil speeches if you think you're so Clover
In conclusion, you're a loner, leftover, seceding crossover

You clowns'll get thrashed when I take my bike and bulldoze
You'll be Koopa-Trippin when you stumble over your Dry Flows
Nintendo's ace in the hole, only dug out with a spade
To rehash his bratty role in Smash and games nobody played
Same plot, same hero, same villain, same stencil
Acting like a Spooky Sword, but raps like Halloween Pencils
Now I can't say tier two curses, but I 'swear' we'll be your doom
I can't take you seriously because you're small as a shroom
Don't you ever give up? You're in my Shadow, that's no question
And it's fitting you're a junior, cuz in this battle you'll be second
So here, read the signs, it's about time you found your answer
"Ho ho ho! Well if you're reading this you're dead!", signed, Lancer

Alright Slugger, time for me to leave this figment out of luck
"LoOk At Me! I'm InDiE!" just means you're a Delta-level schmuck
You little brat, shut your trap before I slam you to the ground
And as for papa, well, he plays second fiddle to King Round!
We reuse elements? (Ha!) You have your son's laugh but deeper!
Knock down your house of cards, as the conflict gets steeper
You need the Eastern Fountain to keep rule over your land?
I order the kidnappings of royalty with the wave of my hand
Check my castle, you ain't got Jack, I've got way more traps than you could stab at
You Kris-crossed the gaming scene, now Toby's mad at MatPat
You wanna be a better rapper? Why don't you give the truth a whirl?
You will always be inferior, no one can choose who they are in this world

It's the Bad Guy's verse, I'll show you some real villainy
Dis-Kaard your bad raps, would you really hurt my mini-me?
Double Dash out this battle, that's all you can seem to do
I'm a true Darkner! My subjects are more useful than your crew!
When it comes to the best villains, you're no diamond in the rough
You're too soft and emotionally vulnerable, HeartsDonut?
Do us all a favor, jump off the edge and press Down B
All anyone needs to know is that chopping down your bridge is the key
I feel for your motherless thunderous kids, King Bowser, really, I do
But unfortunately my loyalty resides solely with my Knight's crew!
I thoroughly enjoyed crushing you turtle scum in this battle
Now kneel before your King and become my personal chattel

Who took the rap throne?
And who do you wanna see battle next?
Well, you decide!
This has been Stark's Rap Battles, we'll see you next time!
