Brandon Breyer Scale
Chapter 2 - Tier 3
Chapter 11 - Tier 4
Chapter 30 - Tier 5
Brandon's scale is subject to change as the story progresses. He's still young and is not only getting familiar with his powers but also growing stronger.
For those who say Brandon should demolish everyone with ease. Ill give you a comparison.
Brandon is the same age as Clark from the Smallville show and in that show Clark was no where near as strong as he'd eventually become.
So in those terms Brandon is already far ahead mostly due to him being created as a warrior.
