When I mentioned "the big figure in back" named Gyadou/Gyadoh, I was referring to the one you seem to be calling "Queen Zeal (floating in the background)" in the team sketch with the triceratops. After all, that sketch was new to us, while #5 was in the Ultimania and previously translated. That one had no names at all, only descriptors.
And going from left-to-right in listing the team members, the apparent human Glenn (the guy with the name originally) is the one you've labeled as Magus.
Well, I guess those early names can make it tough to accurately align with their later counterparts, as one can see with the unexpected case of Lucca/Riddel.
