Most of the Guardians names has a French meaning in their names. You can check more about Guardians at: http://megaman.wikia.com/wiki/Guardians
About his name i'm pretty sure it's pronounced as "truit" or "trit" you can check the how his name is pronounced by going to Google Translate, selecting "French" from the "From:" language list and pressing that sound icon thingy there.




However since tomorrow is my mom's birthday, I won't be able to reply to you or people until a bit later in the evening (in my timezone that is.)
