Xerc can do ALL THE THINGS! Al-Cid isn't going to dominate (wink, wink) their attention all the time ;D AND HE RESENTS THAT IMPLICATION THANK YOU
And what the hell am I watching rn omg xDDDDD But yes! I kind of have in my head that you can put on 80s-tastic virtual reality glasses and interact with the GFs to see if you're compatible prior to junctioning? Because that has to be a big deal. Junctioning someone just because they look cool if they're not going to respond well to the character would be a waste of memories, you know? Students gotta be careful when picking their starter Pokemon from Professor Oak!
... I mean.
IDK. My brain is fried from another 13 hours and you guys can let me know if you have ideas on that front. Several GFs in canon demonstrate having a personality, though, so I think interactions of all types (friendly, mischievous, hostile, curious, intimidating, skeptical, etc.) could be possible between potential junctioners and the GFs. And yes. Fenrir is junctionable by the general Garden public, but again! Remember to take compatibility into consideration. Xerc or Dona could like Fenrir and find that they aren't a good fit, personality-wise and when it comes to how the GFs latent abilities/elements will compliment their own
