"they are both the main character who care for their friends and can get angry."

Congratulations you just described roughly 98.5 % of all hero characters in Anime, Manga and pretty much any kind of story ever created!

Sure they have quite a few character traits in common, but that describtion you just gave is so generic that you can fit it to almost any not-evil character and even quit a few of the antagonists too.

And it's the same with all your other examples too. The similarities you list are so superficial and generic that it seems to me that you try to find similarities simply becaue you want them to be there.

Sure on the surface DBZ and FT might have similarities, but in their cores the are very different.
