That could be, but that isn't what's shown. Infact he's actively getting hurt by Vegeta, and the crew decided not to act together anymore now they're back to normal, even though they still have the fatigue they accumulated as kids, as stated by Piccolo.Hugo Boss wrote: Fri Feb 21, 2025 4:27 pm Gomah’s initial struggles could just be him underestimating Vegeta. If his Third-Eye adapts him to his opponent, it makes sense that he wouldn’t instantly adjust to Vegeta’s power jumps. He probably assumed Vegeta wasn’t that much stronger and miscalculated. But once he recovered from SS3 Vegeta’s Final Flash, he moved so fast that Vegeta couldn’t react. That wouldn’t happen if Base Vegeta were anywhere close to SS4 Kid Goku. It just reinforces the idea that Gomah’s power isn’t static, it fluctuates depending on who he’s fighting and how much effort he’s putting in.
Instead of looking at it from Gomah's perspective, you could look at it from Vegetas, who knew what Gomah is capable of (and SSJ4 Goku) and decides to fight in base for the majority of the fight, which is proven to be a fine idea as they are fighting on even ground. His durability is far too high for Base Vegeta to make any noticeable dent though, and we see even SSJ3 cant overcome the Tertian oculus' durability.
Also, this entire fight is against giant Gomah, who is clearly stronger than the Gomah who fought SSJ4 Mini Goku, well up until he turns into the giant form and dog walks him.
Btw, Gomah had another power up before he appeared behind Vegeta, and this was against a Vegeta who was massively fatigued, and even after that Vegeta has the upper hand until SSJ3 was unsustainable. After that he was on the back foot in base. For that reason the Tertian oculus' may be hitting it's limit in regards to notable power increases as it didn't put Gomah on level with a 'relatively' fresh SSJ3 Vegeta, but instead one who was on the cusp of being incapable of sustaining the form (he was panting with every move after the final flash). The next episode will decide that for sure.
