Ignoring any stink-related shenanigans, does Bacterian have enough of a power advantage to take both at the same time? Or can the team win? Goku is tailed.
I feel like Goku would expect Yamcha to be able to beat Bacterian at the 21st, and I don't think Yamcha made crazy gains since the BoDB. I'd say the team wins.
I think Bacterian can beat them both even without his smell. Yamcha praised his physical strength in the prelims and he withstood a serious kick from Krillin in the 21st Budokai (which Jackie Chun complimented). I doubt Goku or Yamcha at the beginning of the series could withstand that.
As impressive as Yamcha's statement about him and him getting up after Krillin's kick was. I don't think Bacterian needs to be that much over the BoDB duo. Goku and Yamcha still have teamwork, intelligence, skill and technique over him. An afterimage/wolf fang fist combo should do him in.
Yea I think it's implied that Bacterian > 21st Yamcha. Why would the author have Yamcha more or less praising Bacterian as a fearsome foe if Yamcha was superior to him?
