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.
- Goku's mastered ultra instinct is a state of being that allows him to move and react without thinking, giving him an edge in speed and agility over Kratos, who relies more on brute strength and strategy.
- Goku's mastered ultra instinct also grants him a tremendous boost in power, surpassing even his Super Saiyan Blue form, which is estimated to be around 4 million times stronger than his base form. Kratos, on the other hand, has not shown any significant increase in power since his God of War III feats, where he killed Zeus and the other Olympian gods.
- Goku's just with ultra instinct is also more durable and resilient than Kratos, as he was able to withstand attacks from Jiren, who was stated to be stronger than the Gods of Destruction.
- Goku's mastered ultra instinct also gives him access to a variety of techniques and abilities that Kratos does not have, such as the Kamehameha, the Spirit Bomb, the Instant Transmission, and the Hakai, which can erase anything from existence. Kratos, while having a diverse arsenal of weapons and magic, does not have any comparable abilities that can match Goku's versatility and destructive potential.
Therefore, based on these factors, I think that Goku with mastered ultra instinct has a higher chance of winning in a fight against Kratos, as he has more advantages in terms of speed, power, durability, and technique.. I would estimate that Goku with mastered ultra instinct has a **90%** chance of winning against Kratos, while Kratos has a **10%** chance of winning against Goku. This is just my personal opinion, and it may not reflect the views of other fans or experts.
