Btw: New data download contained the new cards, the SA for the blue form and golden frieza form is really cool!

You're right, they met in that timeline, but Heroes is just fanservice so they could meet up with the One Piece crew if they wanted to take that route.

In Dragon Ball another timeline pretty much creates another dimension/universe. They only met because Xeno Goku was time traveling after Fu.

As far as I know, going by Dragon Ball Hereos lore, Xeno Goku fought Beerus just like Goku in DBS, however after losing SSG Xeno Goku never attempted to attain the form again and developed SSJ4 instead, while still remaining the God Ki he absorbed during the fight with Beerus. While the real Goku went on to train with Whis.
