Colon II

Colon II is the robot assistant created just for the Scoutrangers. She was created by Yi Chin so the latter could become a ranger (China Dragon). She is programmed to be Yi's best friend and fulfill the roles of an apprentice to Kelsey Taylor, as well as Yi filling in whatever might be requested of her.

Personality
She is programmed so Yi can confide in her as she often gets so wrapped up in her projects that her sanity and social need go haywire.
