Subverted: Emperor Evulz's apparent merry-making is for the purpose of a simple reconnaissance mission.
Double Subverted: But he also visits an arcade to play some video games during the mission.
Parodied: We see an sequence of Emperor Evulz detailing his routine. After a lot of planning for his Evil Plan and committing atrocities, it ends on him playing a video game.
Zig-Zagged: Emperor Evulz spends his free time playing video games...except we find out that he uses the game to contact his allies and set up many of his nefarious schemes...except sometimes, they really do just sit down and relax...which cements their alliance, and strengthens the ally's loyalties towards Emperor Evulz...not that he doesn't find it fun on its own.
Averted: What Emperor Evulz does in his spare time is never shown.
Enforced: The TV show is being sponsored by a game company. Someone has to be seen playing their upcoming video game at least once.
Lampshaded: "In addition to being evil, I also enjoy playing the occasional video game."
Invoked: Emperor Evulz notes that he can't do anything to further his evil plans today, so he might as well play video games.
Exploited: Hero knows that Emperor Evulz is out shopping for video games every Monday so he uses video games at local store to smuggle a bug inside Evil Fortress.
"I don't need a hobby to occupy my spare time with!"
