F.O.R.E.S.T.A.

F.O.R.E.S.T.A., or more properly known as the Full On Reproducing-and-Executing Spear of Titanic Aptitude is the shape shifting spear of Leo, being his weapon of choice for any confrontation and battle.

Abilities
F.O.R.E.S.T.A. is able to change between three main forms despite having more, each granted by the abilities of the Kyousha Kyousha no Mi, due to the fruit's three attributes given upon it: The shapeshifting of an octopus, the memory of an elephant and the never ending replicating ability of bacteria. Like S.W.O.R.D., these three attributes work in conjunction granting the spear the ability to change between all three forms.

This Zeppin can transform between a spear, a pillow which in turn can act as a pillow normally would, or a shield, and it can multiply itself into many smaller spears, hence F.O.R.E.S.T.A's name. Due to Leo's devil fruit, he can use the power of this spear to its utmost fullest, manipulating it freely without having to physically touch it.

Additional Formes
Over time, this weapon has obtained more forms, of which can aid Leo both in fights, and when building, such as a saw or drill for instance.
