You’re right, they are hard to ship, so apologies if this is a bit shorter than the other asks I’ve done. 

Giovanni
– My NOTP for them
Not the hugest fan of Gio/Cyrus (AbsoluteControlShipping) but that’s more to do with me not shipping Cyrus with anyone.  
– My BROTP for them
This one is weird but I like the idea of him and Nanu knowing each other/being friends?
– My OTP for them
Giovanni/Angelo aka my crack pairing of Gio and Lyra’s dad whoop. They’re childhood friends in the fankid AU and are each other’s one true love~
– My second choice pairing for them
No one.
– My fluffy pairing for them
Gio/Angelo.
– My angsty pairing for them
Giovanni/Ariana (SilverSpawnShipping) since they were an unhealthy relationship in mine. Otherwise, unrequited Archer/Giovanni (SubordinateShipping).
– My favorite poly ship for them
None.
– My weirdest pairing for them
Gio/Angelo, by virtue of it being an OC/canon pairing.

Maxie
– My NOTP for them
None.  
– My BROTP for them
Maxie/Courtney. 
– My OTP for them
Maxie/Archie (HardenShipping).  
– My second choice pairing for them
None. If it’s not Archie it’s not anyone.
– My fluffy pairing for them
Maxie/Archie.
– My angsty pairing for them
Maxie/Archie, it’s my only ship for him so it gets all the fluff and all the angst and everything.
– My favorite poly ship for them
None.
– My weirdest pairing for them
None. Maxie/Archie is mainstream.

Archie
– My NOTP for them
None.  
– My BROTP for them
Archie/Matt. BROS.
– My OTP for them
Archie/Maxie.  
– My second choice pairing for them
Archie/Shelly (ShiverMeTimbersShipping)
– My fluffy pairing for them
Archie/Shelly is probably fluffier than HardenShipping tbh.
– My angsty pairing for them
Archie/Maxie, especially if it’s a love/hate type thing.
– My favorite poly ship for them
Maybe something like Archie/Shelly/Matt (AquadanShipping)?
– My weirdest pairing for them

None, really. I only ship him with Maxie or Shelly and both I think are fairly mainstream for him.

Cyrus (I hc him as aromatic so ….. this will be brief).
– My NOTP for them
None. (Excluding obligatory ‘they’re related in my headcanon’ squick ships Cyrus/Johanna and Cyrus/Dawn (AkatsukiShipping).)
– My BROTP for them
I think under different circumstances he and Cynthia could have become good friends.
– My OTP for them
None. I don’t ship Cyrus with anyone.
– My second choice pairing for them
None.
– My fluffy pairing for them
Cyrus/Happiness.
– My angsty pairing for them
Cyrus/the Void. (But more seriously, unrequited Cyrus and any of his admins, especially Saturn.)
– My favorite poly ship for them
None.
– My weirdest pairing for them

None. (wow this was easy round)

Ghetsis (I also hc him as ace/aro so this will be brief yet again.)
– My NOTP for them  
Since he’s not interested in relationships in my hc….. kind of anyone?
– My BROTP for them
Does he even have friends. Maybe once upon a time he had a bro. Or some of the more fanatical sages.
– My OTP for them
None.
– My second choice pairing for them
None.
– My fluffy pairing for them
None.
– My angsty pairing for them
I guess any scenario where he’s forced to be in a relationship since he would hate that but don’t we want him to suffer.
– My favorite poly ship for them
None.
– My weirdest pairing for them
No ships for the nasty man.

Lysandre
– My NOTP for them
None, really.  
– My BROTP for them
I hc him as having been a father figure to Alain and Calem, so them I guess, but hopefully in a happier world where he didn’t try and kill everyone. 
– My OTP for them
Lysandre/Augustine (PerfectWorldShipping).
– My second choice pairing for them
Lysandre/Malva (BeautifulWorldShipping)
– My fluffy pairing for them
Lysandre/Augustine in a happy AU.
– My angsty pairing for them
Lysandre/Augustine and Lysandre/Malva in canon.
– My favorite poly ship for them
Augustine/Lysandre/Malva or something who knows.
– My weirdest pairing for them

He hooked up with Bryony (RiskShipping) in the fankid AU if that counts.
