Jackal: Assassinated the acting magical government and a large quantity of high-ranking soldiers, a group previously untouched by conflict.

Silver: Froze an entire village of giants, including their spiritual guardian, the dragon Atlas Flame. Instantly defeated Natsu with a wave of his hand. (It doesn't matter that Natsu was fine after defrosting, a defeat is a defeat.)

Tempesta: Unleashes a magical plague upon death that is potent enough to eliminated the Thunder God Tribe, almost killing Laxus (who is an equal to Jura, the 5th strongest of the Ten Wizard Saints), and devastating the entire town they were in.

Kyouka: Has been implied to have killed the entirety of their support guilds with the exception of Minerva, who has since been forcefully turned into a demon. She also brutally tortured Erza for information she didn't have. You can't lie - that was a very confronting scene.

Ezel: Is most likely the demon that sliced up that village and murdered the former Council member. Was left to guard Face, and would have killed Wendy and devoured Carla had the former not accessed Dragon Force, a power capable of breaking Jellal and Zero. This was only possible because of the Eternano-infused air, if it had been anybody else, Face would have probably activated.

Sayla: Successfully killed a council member, then took control of Elfman, and though her assassination of the Fairy Tail members failed due to Cana's intervention, she was still able to bomb them at the heart of their guild - which is now a crater. Was able to absolutely devastate Mirajane, almost tearing her body apart, and was only stopped by a surprise attack by 1,000 pounds of hard muscle falling on top of 200 pounds of unsuspecting femininity - and that's how the chapter ended. She could still get back up in the next release.

I know that they're being defeated rather easily, but you also have to consider that part of that comes with their ability to regenerate. Their strength is their immortality. And while the pacing and structure of this arc seems underwhelming, when you look back at everything they have done, Tartarus has actually been a very threatening and successful antagonist. They have killed and destroyed far more than any previous foe.
