Ironus' would be Wayva. If anyone ever does her harm, their wall may be used as a doorway soon after.

For Joltenne it'd be her friends across the regions, as well as her "GramGram" and her late older sis Cobalt.

For Kaito, it'd be the newfound family he had found in Prof. Cedar, Summer and Briar who have made him finally find a place to come back through between all his world traveling.

Estella: Probably Nike (her Cinderace). She does love her family, but Nike is practically a sister to her by this point.

For Norrie, her grandmother and Ohtli. Charlie too…

It feels like a copout answer but for Jin and Mary it would be their family, their kids and of course each other.

For Norra, it was her Dad up until his disappearance. After accepting and moving on from it, Dulse became the most important to her, thanks to the time they spent together.

For Eudoxia, it's Bozidar. They started as rivals, but then grew into a mutual friendship over the course of them training under Kristoff. When she doesn't understand something, and want input on how something works, Bozidar is the first she goes to.

currently either her missing brother or Her trevenant that used to belong to him since the trevenant has become her Ace and Closest pokemon

Elio's grandfather - Wolfgang Argentium, the patriarch of the Argentium family and one of the most influential people in Unova. Though, this applies to the rest of his siblings as well, who do their utmost to never let him down. The perfectionist mentality that formerly plagued all of them was rooted in wanting to live up to Wolfgang's (imaginary) expectations, even though he ultimately wanted his grandchildren to be happy and live life to the fullest.

Elio modelled his personality after his grandfather, especially in the latter's younger years - while keeping a certain level of distinction, per his desire to be his own person.

For my Oc Claris it has to be Sarin as he was the first friend she's ever had and got her out of the isolated bubble she put herself in.

Ooohh good one! With Stahl & Arryn? Each other and their son - easy. Mind you to Arryn her Lucario does get close.

As for Avian? It's complicated. He doesn't see his family as often as he should and his dedication to prove himself to a corporate machine that will toss him aside the moment he's an inconvenience and when it comes to friends he can count them on a single hand and the number isn't getting any bigger. He needs to learn to love himself that's the issue.

For Wily it's Mahra, and it goes both ways.
