Dragonball the Movie

[Belle Hibiki]

I think what people object to is the idea that he would make an excuse. In the Cell saga, Goku did say he would probably get his ass kicked, but he never tried to AVOID the fight by going "N-no! He's too strong for me!" He tried his hardest, then when it was clear he'd been beaten, handed it off to Gohan.

Significantly different.

But ultimately irrelevant, since this isn't a cut+paste of Dragonball.
