>>5684694>>5684420Dragon Ball has always had people gain unbelievable bursts of strength in jarring shock to their emotions. It isn't just saiyan exclusion that led to prodigious power, humans especially have this in spades with faculties like hysterical strength, flow states, berserker trance, and adrenaline rush. You could easily factor such a thing as needing a certain state of mind for a spiritual transformation, ki control to break the outer shell limiters, or going the same battle power midichlorians that they had the Saiyans adopt. Hell, I'd settle for needing a conduit like unlocking one's potential a spiritual/magical technique to draw it out.
Had to break this into 3 chunks in order not to get cucked by the word limit and align it with my pic examples. I fell asleep when the conversation was taking place and was debating on whether or not to bring it back once the session for today's game was done. But laziness won in the end.
