Fawful is one of the most inspirational villain of all time.
Think about it. In his first appearance, Cackletta describes him as the best minion she has, and she MEANS it. He destroys a FLYING BATTLESHIP with his HAT.
He then kidnapped the prince, turned him into a dragon, destroyed his rescue party AND blocked the path in a little more time then it took the bros to get 100 coins.
He then proceeds to build robot peach replicas using the stolen voice, and gets THREE voices for the price of one! When his master falls, he quickly pulls out his trusty headgear, Saves her soul, and then scours the land for someone he can use to save his master
Then, at the end of the game... He realizes it.... Why is he working for Cackletta? He doesn't need Cackletta. Cackletta needed HIM.
Due to a poorly designed attack, he somehow loses with an impregnable defensive robot, and is sent flying out of the castle.
But he's not done.
Beanless, and with no place to go, Fawful retreats to the one place no one would look for him: The sewers under his enemies castle. There, he works. He makes commerce, creating the most powerful badges the world has ever seen, even one that allows infinite use of items! THE DUDE HAS A SOLUTION FOR WORLD HUNGER
He trades his way up, selling and buying
until...
Until.....
The day comes. He is ready. He has found a minion who was as faithful as he was. He has built his army, and is ready. He attacks, with full force and might, and takes down the two greatest powers in the mushroom kingdom, Bowser and Peach, with one simple item.
He then takes over the castles, remodeling them and brainwashing who he can, locking away those who resist.
And yet.... He's the most thoughtful tyrant who's ever attempted world domination. He cooks for them. He preforms for them. He pays them well, and works with them to achieve victory.
He doesn't sit on a rocket powered chair, letting everyone else do his bidding, He's in the fight.
He's adding nuts to statues, He's carrying princesses away, he's turning CASTLE INTO GIANT ROBOTS WITH BLACK HOLE GENERATORS
He's in the fight, and does EVERYTHING he can to ensure his success. Because he knows what it's like to be the minion. And he'll do everything he can to help them out.
He might of fallen in the end, probably because he overestimated his ability to fight Bowser, but it doesn't matter. He will always be the minion, who rose from the bottom of the barrel, to the top of the food chain.
All Hail Lord Fawful
