Tai Chi Chasers ( , Taegeuk Cheongjamun; known as , Tai Chi Senjimon, lit. "1000 Characters of Tai Chi" in Asian territories) is a South Korean action-adventure cartoon series.

From the 4Kids website:

"After a strange and devastating attack on his home, a young boy named Rai is shocked to discover he’s a secret descendent of the Tigeroids ( ): an ancient race of peaceful beings locked in a struggle with the ruthless and cunning Dragonoids ( ). In a parallel universe called Suhn, the Tigeroids and Dragonoids are battling furiously to recover 500 lost tai chi characters. Whoever retrieves these precious and potent symbols will possess the ultimate power to rule their realm... and destroy their enemies. As Rai hones his innate tai chi skills to fight the Dragonoids, he must find the lost tai chi and battle to become one of the champion Tai Chi Chasers!"

Being a Korean production, Tai Chi Chasers utilizes Korean hanja to represent the various Tai Chi powers. In the 4Kids version, the symbols are referred to by their Korean pronunciations, as well as their English translations.

Rai (Tai Chi Chasers) has not been a contender in any CBUB matches.
