I am talking about when the Tokimi and Tsunami collided there attacks together which eradicated a good portion of the galaxy around them. It did nothing to Rhyo-oki. Which goes to show Tsunami was protecting both it and Z.
And funny how you keep saying they have survived a lot and yet do not seem to post any feats. You claim to have posted feats yet you have not. Post scans/videos of feats you think make Z so durable.
And again, it was stated in the show that Tenchi was able to leave the black hole with the others due to the anti gravitational powers that the light hawk wings produce. Gravity literally means nothing to it and not even the pull of a black hole would take effect on him. Again, not a durability feat. It is capable of negating the infinite gravity and time dilation of a black hole.
And the manga is non-canon. And what are you talking about? If you are talking about "what if superman was a Z fighter" I was adamant of solid feats in that thread to. So...what is your point?
