Legend of the Super Saiyan (Transformation Discussion)

[Goku]

So this is a looooooooong way off from being something I really need to worry about but I have been planning out Goku's transformations in my head and there is a minor problem with them: There are just too dang many of them. 

My initial plan was to go: Kaio-ken > Super Saiyan > Super Saiyan 2 and then just have that be as far as he can get in the Omniverse for whatever reason.

But that didn't sit well with me as it felt like a bit of a cop-out. So I thought about it and I came up with this as a solution: 

Kaio-Ken > Super Saiyan > Unlock Tier 3 Transformations > Sell back Kaio-Ken & Super Saiyan > Buy 'Mastered Super Saiyan' > Super Saiyan 2 > Super Saiyan 3 

That kind of works because around the time Super Saiyan becomes mastered he doesn't really use Kaio-Ken at all any more, and he shows off Super Saiyan 2 and Super Saiyan 3 at right around the same time. Also, whatever tier 3 I wind up getting, it is REALLY exhausting to use and that fits Super Saiyan 3 perfectly. 

Or in the other direction, I could shut him down even further and have his transformations be Kaio-Ken > Fake Super Saiyan (A weird semi-canonical movie transformation which is a halfway house between Kaio-Ken and Super Saiyan) > Super Saiyan and REALLY play up the power of the original spiky blonde.  sj:

On the other OTHER hand, Dragon Ball Super adds a whole new raft of (ridiculous) transformations any one of which might be fun to have as a final capstone (and Super Saiyan 3, well... aesthetically... lets be honest, it isn't Goku's BEST look.)

So what do my fellow Omniversians think? What would you like to see? Please feel free to offer alternative suggestions!
