I suggested this before. And you guys are DBZ Newbs

Cell, Gohan, Roshi, Tien, Yamcha, Gokou, Granpa Gohan, and Krillin are the only
ones who know how to use Zanzoken (which is the same teleportation
you see today in ESF) Only they dont show after image technique.
It'd be useful as hell to confuse blockers But the team never read
my Idea I think.
Anyway, Yeah it'd be useful. And Gokou and Cell do it in the
Cell Tournament when their trying to hit each other too. In Namek
Saga he does it when hese fooling' around with jeice and baata
its not his speed. And he does it when Frieza is trying to run away
from him in battle (one of the last episodes of frieza saga) Where
Gokou tells Frieza to give it up cause its over and he feels that his
energy is draining fast. And Gokou just Zanzoken's behind him
and follows him while freiza is clueless as to where he went.
You can also tell the diffrence between the after image of their
speed and the zanzoken. The Zanzoken literally leaves an image
behind for like 5-10 seconds unless its hit by a solid object.
