A poem about an alien

aliens emerged from their spaceship
disguised as humans they walked
a big baddies convention was going on
drug lords, syndicates, crime bosses
racketeers, gamblers, cartels, triads
aliens took them all to their mother ship
put inside their converter machine
and when the baddies returned to Earth
they’ve all been converted
to the opposites of who they were
and life on Earth was better than before
