Vagrant Lustoid 2

Hair means nothing, as far as I'm concerned. Yes, they look a little different, but this is probably because of a shift in how they channel the energy. I feel that MSSJ is a two-part thing, energy wise. The first is that the energy of SSJ, whilst still the same sort, is channeled more efficiently or in a different method, which would explain physical changes (since given that MSSJ is simply SSJ in control, there shouldn't be any difference unless something altering physical aspect is controlled) and would provide a degree of increased power, given that the energy is being fuelled more effectively.

And the second part is that they have a huge amount more of the energy to spare, thanks to not having to transform, which when combined with the more effective control and circulation of energy results in a massive power boost. That's just how I see it anyway.

As a result of this, I see what they use in the Buu saga as sort of a semi-MSSJ. That comes from the power circulation thing and does increase power more than SSJ. However, with all the training most of them did, I figure that the loss of the total MSSJ state was cancelled out by the increases in power.

As I stated before, I believe this because it was stated that part of the choice to move to MSSJ is to remove the loss of energy gained from transforming, and it seems to be heavily implied at the least that this is done by learning how to stay in that form indefinitely. This means that after the initial transformation you can recuperate the energy lost through transformation by resting, sleeping, eating, whatever, and then later on realise that energy through improved ki circulation. Hence why I don't believe you can get the full effects of MSSJ moments after transformation unless you pop a Senzu or something.
