Legitimately, Mega Man Legends and Mega Man X had some significant issues between "timeline translations" on other terms, so I could see it going either way. In the original script, If memory serves, MegaMan Trigger is distinctly an "irregular hunter" in MegaMan Legends info dumps, which would align his title with the Irregular Hunters of the Mega Man X era. Mega Man Legends America Style just makes him a "Purifier Unit", which gets the point across, but drops the potential "Maverick Hunter" legacy significance. At least Mega gets to be an absolute unit?
Hah, indeed.
