Bad Boss: While Drago's introduction in "Beyond the Sea" was a benevolent one, the rest of Dagur's tenure as one of his minions involved being bossed around, shouted at, burned, beaten, strangled, humiliated, or had his life threatened. The only reason Dagur let it go on was the promise of vengeance against Hiccup and Mirabel.
The Friend Nobody Likes: While Ragnar the Rock thinks that all of them being Co-Dragons makes them friends, the rest of Drago's Elite generals hate him because of this, seeing him as nothing but a clingy imbecile.
Horrifying the Horror: While Dagur tends to act more of a wise-guy to Drago than anyone else, even he knows when to shut-up around him.
Hypocrisy Nod: The irony isn't lost on Dagur that he had declared war on Berk for "conspiring with a dragon army" when that is exactly what he's doing with the Northern Alliance.
He calls the Berserkers disloyal because they were unwilling to die for his ego.
Berk "conspired" with a dragon army when he was the one who declared war on them by kidnapping an ally — violating Sacred Hospitality — for entirely selfish reasons.
Hiccup betrayed him by choosing a "coven of magic-users" over him, even though their relationship was entirely one-sided and rather violent.
He thinks the Madrigals "tricked" him into thinking they were gods when that was entirely his assumption.
Vile Villain, Laughable Lackey: Drago and Dagur seem to have this type of dynamic, Drago being the glower brute that sucks all whimsy from a room while Dagur tries acting all chummy and start small-talk around him (as fruitless as that would be).
Would Hurt a Child: Griselda the Grevious was perfectly willing to maim Karla for her insolence, the only thing stopping her being Dagur.
