Full list of appearances
Col. Mason Truman is a military officer in charge of all the defense of Corinth City, and is the father of RPM's Red Ranger, Scott. He was in charge of the final battle against the attacking Venjix forces, just before everyone managed to escape into the city. He had his two sons fighting in the Air Support division during the battle for Corinth, though it was clear he held a lot more faith in his older son, Marcus, to the point of asking Scott to try to stay out of his brother's way when they went into combat. Unfortunately, during the battle, only Scott survived.
The Colonel is a very 'tough-as-nails' kind of guy and does not show emotion. While keeping Corinth City safe, he also remains in contact with Doctor K, so that the RPM team can protect the city as well. He also was involved with a project that created a special (though outdated looking) trailer vehicle, known as Project Go-Onger (an interesting nod to the sentai series that R.P.M. sources footage from), that supposedly was built for exploration purposes, and has attack and defense capabilities. According to Scott, it is Mason's most favorite possession in the world.
Following the end of the war, while continuing to lead his troops, Mason decides to give Scott the leadership position in Eagle Squad.
- Colonel Truman is unique among all the Power Ranger characters in that he, alone, is seen using swear words, albeit minor curses (specifically, the word "Damn").
- James Gaylyn has also appeared in the movie Wendy Wu: Homecoming Warrior along side Anna Hutchison (Jungle Fury) & Sally Martin (Ninja Storm).
- James Gaylyn also has history as part of the Power Rangers franchise. He first appeared in the episode The Samurai's Journey in Ninja Storm, playing the Ancient Sensei of the Ninja Academy. He also provided the voices for Zeltrax in Dino Thunder and the Orange Heads in SPD.
- Some people consider him similar to Aya Odagiri from Choujin Sentai Jetman
- Colonel Truman's uniform bears a direct resemblance to those worn by officers of the Galactic Empire in the Star Wars movies. The most noticeable correlation is in the grey color scheme and the usage of colored tabs to signify rank on the left side of the uniform. However, Truman's deviates in having three rows of colored tabs, where no Imperial officer seen in the Star Wars movies ever had more than two rows. Additionally, the buttons that are visible on the left and right side of Truman's uniform are not visible on the uniforms of Imperial officers.
