Question

Its the only Pokemon that can learn searing shot and v-create so whats his TRUE signature move?

Comments

A Pokemon can have multiple signature moves. Take Vespiquen.

Answer 1

V-Create and Searing Shot are both signature moves of Victini, but since V-Create is only learned on the 14th movie Victini, I would predict that its true signature move is V-Create. Plus, signature moves are usually powerful and V-Create is more powerful than Searing Shot. Here is a link to the move V-Create:
