... is because the mini type for Transformers (not specified as to which continua) is listed as mini-Ick-Yaks (developed during a Board conversation), and the mini page states the following:
"There are probably some instances in which minis were named before this rule was agreed upon. In that case, if the original mini-namer can't be found and there are no instances of that type of mini anywhere, it's probably okay to petition the Board to make them something different if you want to."
Underneath the mini-Ick-Yaks:
"This mini type is not yet official and can be changed by the first writer of a Transformers OFU or the first to write a Transformers mission that produces a mini."
I just wanted to be on the safe side and petition the Board first before I finish the mission.
As for the mini-Seekers, perhaps they could be added to a different continuum of Transformers? (Since I'm talking about the Aligned Community minis and there are so many continua of Transformers that we could maybe have different minis. Big maybe, though.)
Tl;DR: Mini page said to petition the Board if the mini type was unofficial; therefore, I am, just to be on the safe side. Also, Transformers has a ton of different universes.
