Koko is a green and white electric engine. She is an advanced trainee and one of the main three characters of Chuggington. She is also the leader/singer of the "Rock 'n' Rollers" - a band she formed with fellow trainees Wilson and Brewster.
Plots[]
During her first delivery outside of the Depot, a power cut occurred, causing Koko (an electric engine) to become stranded in the countryside. Wilson and Brewster, who were not far behind, noticed this; Wilson took her back to the Depot while Brewster finished the night shift to Tootington himself. Soon after, Koko would become the winner of the annual Chugger Championship that happens.
Koko would eventually go on to join the Speed Fleet with Hanzo; also receiving her own passenger service. Koko also received a removable speed booster- of which, while efficient, was the culprit of numerous incidents, such as nearly colliding with Brewster and becoming a runaway.
After many years of defending her title as the winner, Brewster and Wilson would eventually win the Rip Roaring Relay Race; even so, Koko would still keep Zephie (who is not the fastest or strongest chugger for sure) as her partner indefinitely, after being very impressed by her keeping up with Brewster for the entire race. Around this time, Koko along with Wilson and Brewster would form the band, the "Rockin' Rollers"; unfortunately however, on the morning of their first performance, Koko's horn broke. Despite many struggles, the three trainees were able to still make use of Koko's broken horn during their first performance.
Personality[]
Unlike Wilson and Brewster, Koko is completely electric and uses her own power directly from the tracks beneath her. She loves to race others, knowing full well that they don't stand much of a chance against her. Despite having such pride in her speed, Koko still cares about her friends and never takes them for granted.
Even so, Koko still has a lot to learn. In addition to being overly competitive, she is also very adventurous and sometimes lets her curiosity get the best of her, causing problems for both herself and other chuggers. She also sometimes feels that getting revenge is her best option; when she painted Zephie's face with spiders out of anger for her. Despite her faults, Koko is still a chugger that you can count on, and she is proud to call Wilson and Brewster her best friends.
Basis[]
Koko is based on the 0/200 Series Shinkansen, a Japanese bullet train. Koko has a large light on her front, which resembles a nose. The real 0/200 series does not have this feature. instead, they have two smaller lights to either side of what would be the "nose" on Koko.
