Do we have this one? I've looked and it doesn't appear to be anywhere. Usually their friend from the very beginning and will remain so until the very end. Bonus Points if they're a little chubby or nerdy (or at least to begin with). Examples:
- Ron in Harry Potter.
- Both Donna and Amy in Doctor Who (2005- series).
- Carl in Jimmy Neutron.
- Chuckie in Rugrats and, later, All Grown Up!.
- Alan A. Allen in Thunderpants.
- Gwen in Ben 10.
- Jazz in Danny Phantom.
- Dez in Austin & Ally.
- Milton in Kickin' It.
- Luther in Zeke and Luther.
- Sideshow Bob (to Krusty) in The Simpsons.
- Willow in Buffy.
- Jenny and (arguably) Chowder in Monster House.
- Rowley in Diary of a Wimpy Kid.
- Neil in ParaNorman - though a stop-frame animated film, the characters look surprisingly like their actors; Neil (Tucker Albrizzi) is one of these.
- Tyler in Big Time Rush.
- Jake in Good Luck Charlie.
