They stated that apparently universe 7 got dealt a REALLY bad hand. Between Freeza's planet/race killing empire, Buu wiping out entire galaxies, and Beerus being overzealous about his work, universe 7 only has 28 planets with their own unique sentient races to them. On top of that, they don't have time to go to the other planets so they figured they'd just stick with earth and hope that the other universes don't have anyone stronger than Gohan or Piccolo, letting characters like Krillin rely on tactical manoeuvres and trickery.hermes said:I am not concerned about that. In fact, it helps mitigate one of the main issues I had with the Tournament arc: everyone strong enough in the universe is from Earth... Everyone.
Sure, there are some aliens (that live on earth) and some androids (created on earth), but this is a team composed of the strongest characters in the entire UNIVERSE. It shows some very restricted imagination when there is no one else, in any other planet, that is strong enough to reconsider Tien or Krillin. It was pushing it when the extended cast was the strongest people in the galaxy (and Roshi), but now we are talking universe level and nobody joined? Really? With all the examples of aliens they found semiregularly, there is no one stronger than Roshi?
After seeing the episode I can guess they're probably going to try pulling something like having to take out Freeza before the tournament begins or they get him DQed somehow. All I know is if Yamcha does wind up replacing Buu, and it turns out he's gotten strong enough to top at least Tien, I'll be happy. "Did it even occur to you guys to ask me?!" Then proceeds to show he's been pushing himself to get stronger ever since Beerus showed up and the reason he hasn't been fighting is because nobody bothered to ask.
