Bowser

I'm the best there is and the best there ever will be! I'll defeat you so badly, you'll wish you never faced me in the first place! You should just give up! You've got NO CHANCE!

Bowser: No one, NO ONE, is authorized to kidnap the Princess except ME It just wouldn't be right!
Bowser: Gwa ha haaaaa!
Bowser: Bwaaaa ha ha! The water's great, eh, Jr.?
Bowser: The royal Koopa line is strong as ever!
Bowser: BWAHAHAHA! You finally made it! Just in time for me to stomp you into space bits!
Bowser: BWAHAHAHA! Not bad! I guess I chose the right guy to be my archenemy. At least you always put up a fight. But it's too late for you because my master plan is almost complete. Tough luck, Mario!
Bowser: RAWWRRG... Now I know why you're my archnemesis. You're so annoyingly hard to squish! Good thing I win anyway! HAH! While we've been playing, my master plan has moved on to the next phase. Tough luck, Luigi!
Bowser: GAH! Give it up already! Why won't you stop trying to mess up my awesome master plan?! I'm building my new galactic empire right here! And you can't stop me! Why don't you just run off and find some green pipe to hide in?! Can't you see that I'm busy here?! I don't have time to chat, so let's cut this short... Shorty!
Bowser: This is the end... for you!
Bowser: Gwahahaha! Crashing the wedding, You? That's tacky, even for you!
Bowser: And are you trying to scare me with that... totally scary costume? Well, it didn't work, all right?! And y-you WEREN'T INVITED!
Bowser: Bwahaha! Whoo-whoo! Now that Bowser's on the scene, you're on a one-way trip to pain!
Bowser: Hey, origami girl! Look at me. I'm Bowser! I breathe fire and punch through solid rock sometimes! You think I'm scared of that little twerp? Plus, I mean... I'm raising Junior! You think that's easy? Try parenting a high-energy kid with access to a flying car and his own army! Your brother doesn't scare me. (To Olivia before facing Olly.)
Bowser: GAAHAAHAA! I FEEL GREAT! FINISHING YOU WILL BE CAKE!
Bowser: I AM THE BEST
Bowser: My First starring game, Super Mario Bros., tells the tale of a WONDERFUL HERO named Bowser who hangs out with a princess and is then MERCILESSLY ATTACKED by a guy in a red hat.
Bowser: LIKES: Spitting fire, driving karts, airships
Bowser: DISLIKES: Mario, Mario, MARIO, poorly constructed brick bridges
Bowser: I AM ALWAYS THE LIFE OF THE PARTY!
Bowser: DID I MENTION I AM THE BEST!
Bowser: But... But I'm Bowser! I'm grade-A, 100% prime-cut final boss! I'm going to take over the world any day now! No way am I helping Mario! He's always trashing my awesome plans.
Bowser: Fungah! Foiled again!!
Bowser: Gwah! You call this a vacation spot!? I’m gonna make a mess of it! Mario’d better get his F.L.U.D.D. ready!
Bowser: Grrrr! You! You were too chicken, so I came for YOU! Yeah! Let's play ball!!
Bowser: Peach! I've come to kidna...Ahem! I've come to play a baseball game!
Bowser: So, you finally got here, You! You're so late...and I HATE waiting! It's not like I blocked the road with rocks or anything! What? I'm serious! What's with the dirty look?! Anyway, let's just forget all that. So, you think you have the mightiest team now? I'll be the judge of that! Here we go!
Bowser: You mean WE'LL rule with iron FISTS, right?
Bowser: Iggy! Wendy! Fall back!
Bowser: SHOWTIME
