^^Hawk mama the strongest XD.
On a serious note she and hawk are some powerful beings with Hawk tied up with Mel's cycle of reincarnation like Liz, I wouldn't be surprised if he transforms into something else.
-Mel will get his black hole-esque power back which we saw in the Vampire spin-off with which he wiped off the Kingdom of Danafor.
-Galan still can not identify whether he killed the enemy or not XD.
-And it is Metrona which is back not dolores as on Pg 21 it seems her right leg is missing which was injured in the Diane gaiden.
-Mel will get his power back, Diane will train with Metrona, Gowther already is powerful enough (based on Galan fight), Escanor is full hype, so now it remains to be seen how King, Ban, Merlin will become powerful to face the Commandments.
Arthur in the end might get some new powers too(though he has to get King's Chastiefol in the end XD).
