- Complete Monster:
- Titan is one of Equestria's Elder Gods as well as the father of Luna and Celatias. For all his talk of being the rightful ruler of Equestria, he shows little to no concern for their subjects, constantly threatening to destroy Equestria if the ponies don't stop resisting his rule and having no problems with killing his own son after he's depowered. His wife Terra was originally married to her brother Empyrean, but had to Mercy Kill him after he was corrupted by Discord. Titan blamed Harmony, his first wife and Terra's mother, for this and killed her. He then forced his daughter Terra to become his new wife, subjecting her to the Insanity to make her into the sort of madmare that seems to greatly enjoy torturing one daughter and trying to kill the other.
- General Esteem is Rarity's father. Whereas Nihilus was created by an Artifact of Doom to be a creature of pure evil, and Titan and Terra are gods who are technically above normal morality, Esteem is just a sadist who's so in love with the concept of war that he raises his daughter via brutal Training from Hell, kills his wife when she refuses to help him unseal Titan, and, upon Titan's release, does whatever he can to crush any resistance. This includes driving the Sliver of Darkness through Twilight's eye to create Nihilus knowing she'll be awake during everything after, brutally killing any pony who opposes the new regime, and upon his death at Twilight's hooves, claiming to have killed and ate Spike as a final spiteful lie.
- Cry for the Devil: Terra gets a flashback chapter that shows how she became the way she is: she had to Mercy Kill her brother/husband after Discord corrupted him, then Titan killed her mother for "betraying" him, forced her to be his new wife, and subjected her to the Insanity so that she'd become as brutal as him. It's kind of hard not to pity her after reading that.
- Fridge Horror: Twilight gained the power of Queen Harmony, becoming able to match Titan, right? And then she drains Titan dry of magical power, effectively becoming twice as powerful as him. I don't remember it being mentioned anywhere that she gave any of that power to anybody else, either. Just think that Titan almost destroyed Equestria and was able to steamroll Princesses Celestia and Luna, both of them at once, with half the power Twilight Sparkle now possesses. Now imagine what would happen if Twilight Sparkle went rogue. There is literally nothing in Equestria, probably nothing in the universe that could contain her.
- Fridge Logic: Apparently Nihilus used an Illusion spell against Rainbow Dash. But to what purpose, considering that during the early phases of the possession Nihilus looked just like Twilight Sparkle?
- Harsher in Hindsight: Pinkie Pie knows every pony in Ponyville. Which means she knows everyone who died during Terra's attack on the town.
- Hilarious in Hindsight: Months after Twilight became an alicorn in the penultimate chapter, the epilogue with her coronation was posted the same day that news broke about her becoming an alicorn princess in the season 3 finale.
- Moral Event Horizon: Assuming he hadn't crossed it before, Titan using the Insanity on Terra to force her to kill thousands of ponies certainly counts.
- Never Live It Down: Apparently one of Harmony's earliest creature designs involved flaming hyenas. Though the "flaming" part may well refer to the way the alicorns exterminated them.
Harmony: You always bring up the hyenas...
- Nightmare Fuel:
- They Wasted a Perfectly Good Plot: Pinkie's nature as an arcpony can be seen as this. While Fluttershy uses her similar status as an eraterus to pit the most powerful dragon in Equestria against Titan, in Pinkie's case it does not really serve any purpose except explaining her powers.
