Yes, according to some interpretations of their abilities, Krillin could defeat Saitama.
Here's a breakdown of why this is a debated topic, based on the reference provided:
-
The Core Argument: The argument hinges on the nature of Ki in Dragon Ball and Saitama's demonstrated weaknesses. It suggests that Krillin's signature technique, the Kienzan (Destructo Disc), could be a fatal blow.
-
Ki and Durability: In the Dragon Ball universe, Ki serves as both an offensive and defensive energy. Characters can focus their Ki to enhance their durability, making them resistant to attacks.
-
Saitama's Durability: While Saitama possesses immense physical strength and has shown incredible durability against blunt force, he hasn't explicitly demonstrated resistance to attacks that bypass conventional durability, such as the Kienzan.
-
Kienzan's Properties: The Kienzan is a disc of concentrated Ki energy known for its incredible cutting power. It's capable of slicing through nearly anything.
-
The Potential Weakness: The theory suggests that if Saitama doesn't have Ki or a similar energy defense mechanism specifically trained against cutting attacks of the Kienzan's caliber, the Kienzan could bypass his immense physical durability and inflict a fatal wound.
In summary: The debate centers around whether Saitama's durability extends to resisting attacks that cut on a molecular level, ignoring conventional defense. If not, Krillin's Kienzan has the potential to defeat him. However, this is a highly debated topic with no definitive answer within either fictional universe. Many would argue that Saitama's unknown limits could encompass resistance to such attacks.
