You know..... this would work with an Anti Robin Hood. You know Robin Hood and his Terrible Men.
Robbing from the Rich & the Poor.
Raping and Pillaging. Friar Tuck is a devil worshipper. That sort of thing.
I once had an even crazier idea.
Take from the poor, give to the rich. The 'merry band' is a group of young nobles dissatisfied with the good king not allowing them to opress and tax peasants enough.
They go into the woods and decide to fight for justice themselves and persuade other rich nobles to their cause.
"You think you don't have to pay taxes because the lord said so, leper ditch-digger? Think again! I, Howard Rood command that you give me your copper pennies so I can donate them to the cardinal! Rich people deserve all the best, not like you, you knave! Uh oh, here come the goody two-shoes guards!"
