Damn, that hair is on point
How many pins to keep the jacket in place?

Enjoy the city
If you have time you should check out Kensington Market if haven't already planned to

They literally only know the move hidden power, a 60 base power move that changes type based on IVs
And their stats are trash too
In other words: unusable

Ooo, Espeon is nice choice for Sol
Unown is appropriate thematically but I definitely wouldn't have put an Unown on his team xD

I considered Honchkrow for Mammon but went with Corviknight instead
I didn't realize it was so appearance focused, but I guess Mammon is too, in his own way

I like these tho I guess I am surprised Yamper didn't make the cut, too obvious or too new?
I originally consider Alcremie for Beel (along basically all other food mon) but decided it's a better fit for Luke, it's literally a dessert pokemon

Aw, Mimikyu is one of my favourites, I considered him for Levi but decided against it
Togekiss is good one
My main one was Absol because 1) its mega is literally an angel 2)it has premonition of upcoming disasters and comes to aid only to be seen bringer of misfortune

Aw, I didn't know that about Gothielle
Rotom is a clever pick
I think for Barbs I only had Salazzle and Noivern 'cause bats and salamanders ^^;
But off the top of my head Polteageist, the possessed tea pot
(and looking at ghost types I realize I forgot to mention Gholdengo for Mammon >__>;;)

I didn't much get into side characters but I love these choices
I was thinking like... Pyroar and Tyrantrum (like I said not a lot of thought)
Tyrantrum isn't very lika Dia in personality but I thought the spiky red T-rex design was evocative of Dia

Yes, Slacking. It also has the stats of legendary but hampered by loafing off every other turn
I was thinking Darkrai since it's signature thing is putting pokemon to sleep and giving them Bad Dreams
And Komala just to run Choice Band/Last Resort (Comatose is an extremely Belphie coded ability)

Interesting, I don't think I thought of those but yeah fighting types definitely suit Beel
Guzzlord was an obvious one (it literally makes think of Beel), but I'm not very fond of it so luckily Buzzwole is a Ultra Beast that's literally a jacked bug
Also the twins should share a Snorlax

Agree with Enamorus
I think I had Lilligant in the considerations, but the pick I thought first for Asmo was Roserade since he's so associated with roses in particular
Also was struggling with Pheromosa cause it's kind of perfect but not sure he would be cool with bug pokemon ^^;

It probably wasn't going on the team because I didn't want to overload the teams with legendaries, but Mewtwo was tempting with how much great existential angst he shares with Satan
But yeah, Annihilape was definitely going on the team cause, battling reasons aside, I just prefer that design

Aw, poor Levi
Gyarados was 100% my first pick for Levi, especially since in evolves from a notoriously weak/worthless goldfish
I didn't have that many firm picks, but I did like Primarina 'cause it's a siren plus it's got that Shoujo magical girl energy

Agree on Sableye
In terms on thieving I think I went with Weavile with pickpocket mostly for battling reasons, but was sorely tempted to put Meowth which lead to a major struggle on whether Mammon or Satan would get Persian ^^;
