Jeffz0r is a Peach player from 's-Hertogenbosch, the Netherlands. Known throughout Europe for visiting almost every single tournament in the Netherlands since March '05 (DT10) and for organizing the Netherlands' biggest tournament so far, JST5. People sometimes make a little fun of him, when he doesn't make it through poules, but he still takes it like a man and isn't afraid of showing his dancing skills or helping people with traveling to tournaments.
- Jeffz0r is known as the Tournament Travel Agency Tour Guide because he always helps people out with traveling to tournaments. This is only for tournaments in the Netherlands.
- In the Dutch Smash Awards Jeffz0r has won the awards for "most often made fun of" and "worst team partner", although Jeffz0r claims these are undeserved, especially the category worst team partner. According to him, people just thought so at the time, because at the his own tournament (JST5), he and his teampartner (Aniolas from Sweden) didn't perform as well as they could have. Jeffz0r has shown at several other tournaments that he is not as bad as people think though (especially RoX4, where he did surprisingly better than expected).
- Jeffz0r has a friend, called LPU, of whom everyone says he doesn't exist. Jeffz0r used to say often that he'd take LPU to a tournament, but he always cancelled at the last minute. At JST5, LPU did show up though, but everyone joked he was an actor, claiming to be LPU.
- After a visit to the US, someone started the false rumor that Jeffz0r claimed to be #8 in Europe. The Dutch Power Rankings seem to disagree.
