The Superhero Database Classification number, or SHDB Class, is a number that represents the overall 'power' of a character. All traits of a character are used for calculating the Classification.
What it DOESN'T mean
This doesn't mean that a higher class would always beat a lower class character. But the bigger the difference in Class is, the more obvious it is who'll win in a fight.
How is this calculated
( INT^1.3 + (STR*0.5 )^2 + (SPE*0.5)^2 + DUR^1.6 + (POW + (SPS*SPL))^2 + COM^1.8 ) ^ TIER
Super Power Score and Level
Every Super Power has a score (SPS) that is used to calculate the Class. Each Super Power also has 3 levels (SPL). The level is set when connecting that Super Power to a character. The level determines the final score, of the Super Power, being used in the calculation.
- The location and environment of the battle. The Night King might have an advantage in colder and darker places, while Vecna might prefer warmer and brighter ones.
- The number and strength of their armies. The Night King has a vast horde of undead soldiers, including giants, bears, and a dragon. Vecna also has a large army of flesh thralls, spider monsters, and demobats, as well as the Mind Flayer and the Demogorgons.
- The vulnerability and resilience of their bodies. The Night King can be killed by dragonglass, Valyrian steel, or dragonfire, while Vecna can be killed by fire or electricity. Both of them can regenerate from most injuries, unless they are fatal.
- The intelligence and strategy of their minds. The Night King is a silent and mysterious figure, who seems to have a plan and a purpose for his actions. Vecna is a cunning and ruthless leader, who enjoys tormenting and killing his victims.
One way the Night King could kill Vecna is by using his dragon, Viserion, to breathe blue fire on him. Vecna is vulnerable to fire and electricity, as shown when Eleven and the kids electrocuted him in the mall. The Night King could also use his ice spear to pierce Vecna's heart, as he did to the original Viserion. However, Vecna might be able to dodge or deflect these attacks with his telekinesis or illusions.
Another way the Night King could kill Vecna is by exploiting his connection to the Mind Flayer. The Mind Flayer is the true master of the Upside Down, and Vecna is only a servant. The Night King could use his mark to sense and locate the Mind Flayer, and then attack it with his army of the dead. If the Mind Flayer is killed or weakened, Vecna might lose his power and control over the Upside Down creatures. The Night King could then finish him off with his sword or his bare hands.
The mark is a magical imprint that the Night King can leave on someone he touches. It allows him to know exactly where that person is, and to break through any magical barrier that protects them. He used this mark on Bran Stark when he touched him in a vision, and was able to find and attack him in the cave of the Three-Eyed Raven. The mark looks like a circular pattern of frostbite on the skin, and it does not fade away. It is unknown if the mark has any other effects on the person who bears it, or if it can be removed.
A third way the Night King could kill Vecna is by finding a way to enter the Upside Down and destroy it from within. The Upside Down is a dark and twisted reflection of the real world, where Vecna has more influence and resources. The Night King could use his magic to create a portal or a breach, and then lead his forces to invade the Upside Down. He could use his weather manipulation to create a blizzard or a storm, and then unleash his dragon and his wights on Vecna's army. He could also use his necromancy to raise the dead bodies of Vecna's victims and turn them against him. The Night King could then confront Vecna in his lair and end his reign of terror.
(If Demogorgons or other vecna pawns or Mind Flayers try to touch or approach the night king they will freeze to death from the freezing touch (if the white walkers have this power... he has much better...)
If the Night King touched a Demogorgon or a Mind Flayer, he might be able to freeze them or turn them into his thralls.
These are just some of the possible ways the Night King could kill Vecna, based on their abilities and weaknesses. I would say that the Night King has a 60% chance of winning a fight against Vecna, while Vecna has a 40% chance.
