BOSS_RUSH

Once in a blue moon they convene at their seasonal wine-tasting banquet to talk smack about heroes and labor unions.

This year's attendees:
The Enchantress from Shovel Knight
The Nuclear Throne from Nuclear Throne
Lord Arktivus Brevon from Freedom Planet
Ballos from Cave Story
Anubis from Pharaoh Rebirth+
Athetos from Axiom Verge
Satan from The Binding of Isaac: Rebirth/Afterbirth/Afterbirth+
??? from Hyper Light Drifter (Judgement? Immortal Cell? Refuses to sign the guest book)

EDIT: whoops, forgot to mention, inspired in part by I'm the Boss, a tune performed by Big Bad Bosses. You can listen to it here.
