Does Consuming the Flesh negate all effects of action that may target personality? For example i announce Walk in Shadows then move my ninja into currrent battefield and declare to target enemy Personality for -1F Poison token. Player reacts with Consuming the Flesh and negates everything, also movement of my ninja?
Walk in Shadows Battle: Move your target Ninja Personality with no non-Ninja Followers to the current battlefield. You may target a Personality and give him a -1F Poison token.
Consuming the Flesh Reaction: After another player's action targets one of your Personalities in your current army, destroy the Personality and bow this Shugenja: The action's effects do not happen. Create a 2F/2C/0PH Shadowlands • Undead Personality at the current battlefield. Lose 3 Honor.

No, it will only stop effects that occur after the targeting.
In this case it can prevent only the giving of the -1F Poison token as that is the only effect that occurs after the optional targeting - but, since the Personality is destroyed by Consuming the Flesh, that effect will fail anyway, as the Personality is out of play.
