To give them a level of importance and not just these pointless one and done cameos what monsters should the students team with to stop malivore cause they are just as much a part of the story as they are, not only do they have a vast array of magic powers but also I could see cleo and landon meeting with in the dark dimension and some want revenge on him.
but my dream team I guess and Ill try to keep it small to fit realistic expectations, I dont exactly know how many cast you can have in an episode in this covid conditions, but these are the most plausiable creatures to join over even just for 1 episode:
the gargoyle since he hates supernaturals
the dryad since she didnt want to hurt anyone
necromancer, yes i know people cant stand him but im pretty sure he is going to team with hope
the shadow demons, since they werent violent acting
the merman, he also seemed to be non violent, yeah he destroyed property but he didnt exactly hurt anyone and in the prison world he kept to himself not to mention brett or julie clearly likes the costume at least cause he is frequently shown in some fashion
idk whether to add the sphinx, he comes off as neutral like not serving either side
they wont do this cause of how violent he was but id like pothos to come back they clearly had some plan for him before they ditched it
nimue/lady of the lake
puck/robin goodfellow
the leprechaun
the ferryman
and lastly I think the original phoenix might play a part since malivore perhaps stole from them to create landon
thats it I think, I dont know if ablah will return cause she might be too powerful and who knows if she retains the memory of meeting lizzie
