no, thank you
In relation to what are you saying no thank you. Pardon if it's obvious to everyone but me.
It fits having Mr. Thicknose and Grandpa Longneck function as Zordon. Though is this due to both sets of rangers having only 1 "Zordon" type or due to Grandpa Longneck being the "Zordon" for the beyond rangers but he's moved to the great valley for obvious reasons, it's safer for his mate and grandson, he's old and its safer there, ect.
The do make a good pair. Mr. Thicknose knowing a lot of things from second hand knowledge and grandpa longneck having some first hand knowledge and as a former story speaker (if that is canon for here) he knows a lot from the stories and can inspire folks.
I guess by growing (sorry missed a few posts till I went back and looked) you meant up to around average size like as tall as cera or littlefoot are on all fours? I recall power rangers turbo but only saw a single episode I think, way way back when. Or do you mean the gang when they morph grow up to about the size of the fast biters in the beyond rangers group.
I like the guardian term, though it may fit better to have one group called by the name suggested, the 'Beyond Rangers', and maybe the others the 'Guardian Rangers (or do most think a better common term would be "Valley Rangers", "Great Valley Rangers"?. Though that may not be the full name of each team most folks would shorten things down to that, with maybe a few shortening it further to guardians and rangers, depending on the individual person's preferences.
