Grogar teaches Chrysalis, Tirek, and Cozy Glow on how a villain ought to deal with the heroes. The Treacherous Trio pride themselves into thinking that they know it all and have what it takes to be successful villains to take over Equestria. However, Grogar shows a whole other level of villainy...of some sort. A terrifying creature from another world shows them what he is capable of and goes to certain measures they wouldn’t expect and which even Grogar knows would drive the lesson down to home.

(Note: This is set before “Frenemies” MLP:FIM season 9 episode 8)
