Scene stealing NPC's

[Bosh]

When there's a need for the PCs to have allies I tend to make them faceless henchmen (for example a trio of brothers called Alard, Balard, and Calard) who the PCs often end up LOVING and giving all of their handmedown items to, celebrating their killshots etc. or intentionally aggravating NPCs (for example know-it-all wizard with an annoying nasally voice), who the PCs love screwing over. I've had my favorite NPC ally (a sleazy but slightly more competent Zack Brannigan-type) be murdered by PCs in a few different campaigns. I think people who've hated annoying DMPCs before take great joy in doing nasty things those NPCs so I'll keep on using them since I give them zero plot armor.
