Hi there! I'm a huge Dragon Ball fan, and I've been studying the series for years. People often ask me about the whole Super Saiyan 4 transformation, especially with Vegeta. So, let's dive into it!

## Can Vegeta Transform into Super Saiyan 4 at Will?

This is a bit of a tricky question. While Vegeta undoubtedly achieves the Super Saiyan 4 form, whether he can transform at will afterwards is debatable. Here's why:

**Evidence Supporting "At Will" Transformation:**

* Post-Baby Saga: After the initial transformation against Baby, Vegeta continues to use the Super Saiyan 4 form against Super Android 17 and during the Shadow Dragon Saga. This implies he retains access to the form and can transform whenever necessary.
* No Explicit Limitations: Unlike Goku, who struggles to control his Golden Great Ape form initially, Vegeta seems to have better control over his primal power. There are no explicit statements or scenes suggesting he *can't* transform at will.

**Evidence Against "At Will" Transformation:**

* Unique Circumstances: Vegeta's initial transformation is heavily reliant on Bulma's Blutz Wave generator. It's possible that external factors like the Blutz Waves are necessary for him to reach that state.
* No Clear Confirmation: The series never definitively shows Vegeta transforming into Super Saiyan 4 without some external trigger (like the Blutz Waves). This lack of confirmation leaves room for doubt.
* GT's Canonicity: This is a big one. Dragon Ball GT, where Super Saiyan 4 originates, is not considered canon to the main Dragon Ball storyline. This makes it difficult to definitively state anything about Super Saiyan 4 transformations, including Vegeta's, within the broader context of the Dragon Ball universe.

Conclusion:

While the evidence is inconclusive, it's more likely that Vegeta cannot transform into Super Saiyan 4 at will. The initial reliance on Blutz Waves and the lack of clear confirmation suggest external factors might be necessary. However, it's also plausible that he retains some degree of access, allowing transformation under specific circumstances.

Ultimately, without a definitive statement from the creators or further exploration in canon material, the question remains open to interpretation.

Goku asked Vegeta why can't he go SSJ4 without Bulma's device and that pissed off Vegeta. So no, he can't go SSJ4 without artificial blutz waves. Moreover, in the last battle against omega shenron, Vegeta went SSJ2, not SSJ4.read more >>
