Why Didn't Goku Use Kaioken 50 or 60 Times?

Throughout Dragon Ball Z, Goku has utilized the Kaio-ken technique to achieve unprecedented levels of power. This technique transforms him into a powerhouse, but comes with significant risks and limitations. Here are a few reasons why Goku does not push the Kaio-ken to extreme levels such as 50 or 60 times.

Physical Strain

The Kaio-ken technique increases Goku's power but also puts immense strain on his body. Using it at very high multipliers like 50 or 60 times could lead to severe physical damage, potentially even resulting in death. Goku has a limit to how much his body can handle without sustaining serious injury.

Control and Stability

Higher multipliers require greater control and focus. Goku has demonstrated that he struggles to maintain stability at these higher levels. At extreme levels, he might not be able to fight effectively. This is evident in moments where he loses control, especially when combining the Kaio-ken with other transformations or techniques.

Energy Drain

Kaio-ken consumes a lot of energy and uses it at high multipliers would deplete Goku's stamina rapidly. This would leave him vulnerable after a short burst of power, making it impractical for prolonged use in combat.

Situational Use

Recognizing the limitations and risks, Goku tends to use the Kaio-ken strategically. He often combines it with other transformations like Super Saiyan to maximize effectiveness without overexerting himself. For instance, when he faces formidable opponents, Goku uses a multi-step approach, which minimizes the strain on his body.

Evolution of Techniques

As the series progresses, Goku learns and develops new techniques such as various Super Saiyan forms and Ultra Instinct. These new techniques provide more sustainable power increases without the drawbacks of Kaio-ken. For example, the Super Saiyan Blue form uses God ki, and the form was obtained by keeping his ki from leaking out. This form is more sustainable and allows Goku to maintain peak power without the excessive strain of high multipliers in the Kaio-ken.

Overall, the substantial risks and limitations associated with extremely high multipliers prevent Goku from using the Kaio-ken at levels like 50 or 60 times. While the Kaio-ken offers a significant power boost, strategic and controlled usage is key to his long-term success and survival.
