Keeping the world on the same plane, I do not call the fighter NPC a fighter, he is a warrior or a knight or something. This way he can have whatever powers I need and the players cannot say that they should have this or that power. I also tend to give the NPCs powers from 4e like a close burst 1 attack as an encounter power or recharge power. I also give some 5e powers like second wind but may make it heal a set amount to avoid more DM work or even make it a heal he could give another person.
Another thing I have tried in the past is to have the PCs fight each other with 'shadow' characters. A room creates duplicate characters of the PCs that attack each other. The players seem to like rolling to hit each other as their bad guy and then help each other as their good guy. The DM hardly needs to roll anything. You can just let the players handle both sides. It becomes a really tough fight even if you do not have the shadow PCs use the same magic items.
