Transform is a status Normal-type move.
Transform allows the user to transform into the target, copying its moves.
Transform will fail if used against Gamma Urayne.
Because Transform does not copy a target's weight, moves like Grass Knot (move) and Low Kick (move) may do more or less damage depending on what is being fought even though all other non-HP stats are copied.
For example, if a Duplicat that had transformed into a Cocancer uses Grass Knot against it, it will have base power of 120. However, if that same Cocancer were to use Grass Knot against the Transformed Duplicat, it will only have a base power of 20 due to Duplicat's weight.
