Chapter 48: Power Levels
Starter Level
Intermediate Level
Advance Level
Champion Level = some of Ash's pokemon are champion levels while some are at the peak.
Quasi Legendary Level = Bayleef is a quasi-legendary pokemon (Explanation will be given in the future chapters.)
Legendary Level - The legendary level is broken down into 5 ranks, Rank E being the lowest while Rank A being the highest.
Rank S - Pokemon that are labeled as Rank S holds the power to destroy an entire region all by themself.
As we go deeper into the story I released the power levels so that you guys will have a general idea of how powerful a certain legendary pokemon is.
Up to this point, all you know about pokemon in the series/movies should be not applied any further because it will be real-life and gruesome at some point so be aware, so I don't want to see any complaints about how a "kid-friendly" series could be so gruesome or idiotic.
