@BloodSprinkles: with minus being written by toriyama it is probably canon.
@SMXLR8: True very true. But, they both follow their own formula and certain characters don't work or feel right when following the other formula. Goku just isn't DC comic formula material. If that makes sense.
In all likelihood it will never happen. Personally I wouldn't want dragonball to crossover with them anyway. It'd be guaranteed to be westernized and the last time that happened we got Dragonball Evolution. Also, I think one of the major complaints about GT was that it was too western so, yeah. Keep western influence away from dragonball please. Probably the other ones as well. They're better with just crossing over with each other. If they want, do another Marvel/DC crossover and make it canon.
Gotta admit, this is a little funny.
Potara is a form of fusion. Also, considering in the canon the only fusion with vegeta was the one where they became vegito that would have to be the power goku was thinking of. He would not really know how strong gogeta would be. Sorry but ssjg goku is stronger than vegito.
Can't say much for new 52 but Post Crisis would likely lose. Jirou's strength is on the gas giant level while Post Crisis was generally around the dwarf planet level in terms of strength. As the OP pointed he did get hurt by beings of his own strength level so Jirou should be able to bust him up badly with just a couple shots at most.
Freeza busting 6000 earths is a bit much I think. Even if powerlevels and output rose linearly his best feat is destroying planet vegeta which was like busting 10 earths. Multiply by 200 for his final powerlevel and you get around 2000 ish. Don't know what that would really place him at. I still consider him to be around casual Jupiter level.
1. Don't know 2. Croc 3. Croc Stomps 4-6. Don't know 7.Croc 8. Sewer guy from X-men right? Probably Croc. 9. Don't Know 10. Which one was that? 11. Could go either way 12. Not sure 13. Don't know 14. Tough call but probably Baraka in a close one, and definitely the only fight I'd like to see. The rest I don't know anything about these characters.
@DBZ_universe: Yeah, it was part of some interview or something like that that I had read. Birusu being a Yokozuna and Broly being the weakest of the lowest class I believe is what it said. The way I took it is it's like comparing final form Frieza to saiyan saga Vegeta.
@flashback180: Not really, he went in lava with out shield. Surviving planet bustings is also nothing to him. Goku dies in a planet explosion....even Mystic Gohan died in a planet explosion.
To be fair to Mystic Gohan, he was unconscious and not giving off any ki when it happened. Not that I think he would live too much longer without any air. Also, while Birusu, SSG Goku, and Whiss haven't shown galaxy level yet I do remember seeing something about a direct comparison between Birusu and Broly where they basically said Broly would get stomped if he fought him. Something about sumo wrestling rankings if my memory is correct.
