Out of all the big villains in the Marioverse(Bowser,King K.Rool and Maybe Captain Syrup and Wario when he had his crew) who do you think treats their henchmen better?
Personally, Bowser all his guys seem to enjoy working for him while having fear of him at the same time and if i'm not...
It really depends, one reason i find it hard to place them in canon is because Bowser is evil and badass in tha main games while he's mainly comic-relief in the RPG's. Though the first Paper Mario did a good job of balancing the both personas.
