Tocot was a Diagnosan medical doctor who lived and operated on an icy planet in the Uncharted Territories. Tocot had a reputation for being one of the best healers in the Territories. Among his accomplishments was his design of Scorpius' coolant suit. Tocot ran his business with his associate Grunchlk, who handled all of the negotiations for any clients. While he didn't seem to agree with all of Grunchlk's methods, the inability of translator microbes to translate his language made it necessary to have an interpreter and Tocot had to accept Grunchlk's partnership.
