A fusion between The Sage and Yusuke would be awesome. They would have: - Immortality (Goku) - Chi blast in the form of single or multiple (Yusuke) - Flesh melting aura that extends over mountains (Combination) - Hypersonic speed (Goku) - Pseudo flight (Yusuke) - Mountain busting+ Punches (Mostly Goku, but Yusuke brings energy explosive addition) - Lightning and wind controller (Goku) - Fire/heat immunity (Goku) - Amplification of returned energy blast (Goku) - Fingernails that can cut through cliffs (Goku) Surprisingly Yusuke doesn't bring much to the table now that I think about it, but his added power and chi variants should be nice. That said, I don't think the Naruto/Ichigo combo can stand up to that. The best they have is great mobility, a massive energy ball (Naruto's KN4's blast would be greater than Ichigo's) and chakra/reiatsu defense. None which should bothered the Goku/Yusuke combo.
