The Vampire Lords are the toughest vampires, never more than ten at once. So far, I showed five of them actually fighting. Let's recap!
1. Aro
Yes, Aro from Twilight. While his comrades just had the rank, he actually WAS a Vampire Lord. His ability to learn the memories of others allowed him to know fighting styles, dark secrets, and all enemy weaknesses. Also made him great at interrogating. Even his laugh was a deadly weapon. He was too much for the weary Finn and Leah and Marcus had to switch sides.
2. Armilla
The first Vampire Lady Leah killed, Armilla was actually one of the toughest vampires. Her teleportation, while scoffed at by several other vampires, allowed her to go through dimensions, escape and ambush foes with ease. She was also smart and got spells outside her gift. Leah had to exploit a weak point Finn made.
3. Vlad
Vlad was a dangerous Vampire Lord that specialized in Bone Magic as his gift He could summon gravestones and Stalfos, create a sword of bones, even twist the skeleton of the enemy. Finn couldn't beat him, and only Leah was fast enough to defeat Vlad.
4. Fang
The comrade of Vlad, Fang's gift was ice. He could make and regenerate both a sword and an armor of ice, create ice walls and icicles on them, or even those of his foes, and even cast Ice Storm, one of the most fearsome spells. Namely, he actually beat Leah with his ice and destroyed the weapon she used until then by freezing it. Finn had to kill Fang by using his weapons, which were all using heat.
5. Sethian
Sethian was the most recent Vampire Lord, who posed as an elf. His gift was based in Shadow, which allowed him to affect the shadow of himself and others and even become shadow himself. He could give ordinary vampires a small part of his power, fire Shadow Balls or extend the range of his arms. His shadow form was mostly intangible. However, Leah killed him with her new abilities, and Renee damned his soul.
So, which one do you like the most? Which one do you hate? Whose gift do you want to get?
