Trixie

Trixie is Speed Racer's girlfriend, who is always ready to aid Speed in a time of crises. She was voiced by Corinne Orr. In the 2008 film and related video game, she will be played by Christina Ricci.

Personality
If racing is Speed's first love, Trixie takes a close second. But she understands this and is his frequent source of encouragement. She always is right behind him in races (in airplanes or helicopters, but she most frequently used the latter) and makes sure that he's safe to win the race. Spritle is often jealous of her being so close to Speed.

She also uses disguises to get Speed out of trouble. Some of them are so extravagent that even Speed can't tell it's her!

Trivia
Although it's never said in the anime, it is noted that she used to be the spoiled, willful daughter of the head of a rival car company who first meets Speed when she is sent to spy on Racer Motors. When she falls in love with Speed, the plan is foiled. The character's background as a "rich girl" explains why she owns her own helicopter and drives a Mercedes.
