Koko is the primary protagonist of Chuggington. Hanzo is her mentor.


Koko is somewhat mischievous and somewhat in a rush of things. She is also teases some chuggers who prefer to go slow, by calling them "slow coach". She is also curious of what she sees and is anxious to know what anything's about. She usually gets into trouble for having too much fun, and whenever someone disciplines her and ends her fun without warning, she would get upset. But every time it happens, she would eventually discover the wrong-doings she causes and always apologize for her actions.

Phisical Apperance[]

She is a green and purple electric train. She has silver eyebrows.


She is the only female and youngest of the trainees (along with Piper).
