Axel and Rod Skidmark are a pair of Australian cheating and racing brothers shown as the main antagonist of the Hi Hi Puffy AmiYumi episode "Soap Box Derby".
Axel was voiced by Rob Paulsen, and Rod was voiced by Nathan Carlson.
Axel wears a German Kaiser helmet with green shoulder pads. Rod has spiky and orange hair and wears silver armor.
Axel and Rod are overconfident in racing and always rely on cheating. They are abusive to people who have won the championship. They get upset when others win without cheating, especially when Ami does it.
Axel and Rod Skidmark were Ami's neighbors who cheated on Ami's previous soap box derbies she competed in and won the trophies.
Ami, Yumi and Kaz decided to make the Yu-Mean Machine to race against the two brothers. Ami saw the brothers' soap box leak gas, which made her realize they are cheating. The band decided to cheat against the cheating brothers in order to win the race.
While both groups didn't exactly win the race, Axel and Rod picked on the winner and stole his trophy.
- The brothers apply leaking gas in their car to cause oil spills and use a boomerang to hit unsuspecting racers.
- Nathan Carlson provides the voice for Rod Skidmark, who also voiced The Lizard from the Spider-Man 3 videogame.
- Even though the credits list Rob Paulsen as the voice of Axel, Axel only laughs.
