"We can't let a brat like you do as you please forever. It'll hurt Team Rocket's pride over and over again. Making it lessen, you see. …So, it's time to finish you. However strong you may be, if the two of us fight at the same time, you'll have no chance of winning. Don't you agree? Hee hee hee! Sorry, baby. Now, get ready to be thrashed."
