Strongest Form 2

When Strongest Form 1 proved insufficient against Goku's increasing power, Baby tapped deeper into the vast reserves of energy he had accumulated. By draining ki from the millions of humans he had placed under his mind control across the Earth, Baby channeled an enormous amount of external power into Vegeta's body. The result was Strongest Form 2, a transformation that represented the absolute peak of what Baby could achieve through his parasitic abilities without resorting to the Great Ape transformation.

Super Baby 2 proved to be one of Dragon Ball GT's most formidable villains. His power was sufficient to fight on relatively even terms with Super Saiyan 4 Goku, a form that represented the pinnacle of Saiyan evolution in the GT timeline. The battle between these two forced both combatants to push their limits, with Baby eventually seeking the Golden Great Ape transformation when even Strongest Form 2 was not enough to secure a decisive victory.

The form's reliance on external energy sources proved to be both its greatest strength and its vulnerability. While the stolen ki gave Baby access to power far beyond what Vegeta's body alone could generate, it also meant that his power level was tied to maintaining control over the Earth's population. Any disruption to that control network would weaken the form, creating a strategic weakness that Goku and his allies could potentially exploit.
