Coke & Pepsi

Coke and Pep escape many traps as they travel across the country. They are a member of The Genius Files. Many villains did bad things to Coke and Pep such as being frozen to death, boiled in oil, pushed into a sandpit, thrown into a vat of spam, and many more. Sometimes the twins argue for certain reasons. Pep is the one who's good at ciphers and Coke is good at knowing everything when they traveled.

TRIVIA:
In the book You Only Die Twice Dr. McDonald before making name Pep's name thought about name her Ashley.
