You know Piccolo is gonna deliver a Makankosappo by his pose.
You know Goku is about to throw a Kamehameha by his pose.
You know Vegeta is about to do a Final Flash by his pose.
You know Paikuhan(Pikkon to some) is about to do Thunder Flash Attack by the movements he makes first. (I love the power up for that move btw
Ever wonder why? Obviously the real life answer is "it looks cool and makes each person's attacks unique!" That's great and all, but I believe it serves an in-universe purpose too.
My guess is they shape their bodies to concentrate and mold their ki as they build it up for an attack. It's like using different sprinkler attachments on a hose to get various water spray patterns. I like to think ki follows the path of least resistance like wind or water. Attack postures or movements create resistance until it's released on an opponent, and I'm guessing a fighter will intuitively know when an attack is "ready" to fire.
Of course, these postures can be modified if necessary-- like Gohan's one-armed Kamehameha against Cell.
I even think the ridiculous amounts of screaming that goes into powering up certain attacks actually serves the purpose of keeping one's ki under control until it's time to release it.
What do you think of this theory?
