Zero has a Special Bracelet on his Left Wrist Gifted to him by Arceus Herself for being her chosen Champion/Guardian This Bracelet is imbedded with Elemental Gems that allow Zero to Transform into any Eeveelution he chooses. Each Eeveelution holds a Legendary weapon Gifted by his Aunt of the Same typing that the Weapon Represents. This allows Zero use their powers through the weapon.

Zero's Umbreon form is his Primary Eeveelution form. the First and natural Evolution Zero ever took as a Result to this it's also one of his Most powerful and Versitile forms. Boasting the highest stats overall especially in the Defense and Special Defense department like umbreons naturally do. Although Zero is Naturally a Dark type he has the personality of a hero and a heart of pure Gold. He fights to protect and rid Multiple worlds of evil. His Family known as the Blade family has always been under the Protection of Arceus herself. The Blade Family has been tasked for Generations to protect their pokemon world from threats from inside and outside their realm. Due to this The blood in Zero's Veins Drives him to persuit justice and protect the innocent and destroy evil wherever it may lurk. Zero Struggles with his Dark nature though at times that splits his spirit between a destined path of protector or destroyer. because of this Zero hesitates to use dark type attacks in fear or losing himself to the darkness within his soul. Despite this drawback to limited Dark type uses he is still able to use Fire attacks (This is because his spirit was blessed by Moltres and Ho-oh with something called the Phoenix Fire. This blessing is what keeps Zero alive. otherwise his own power could destroy his own body)

With Zero's Dark type capability being Limited the weapon gifted to him is a Sword and Shield Combo given to him by Arceus herself. with the intent that if Zero cannot use Dark typing...then why not embrace the Light type that she possesses. This sword and shield combo eminates with Zero's Aura allowing him to activate the sword and Shield like Energy. The Sword's blade is Energy and can be activated and Deactivated using Zero's will. and the shield when Deactivated just looks like the Symbol of Arceus. showing that he is indeed Arceus' chosen Champion and Guardian. The power of Arceus' weapon is similar to that of the Master sword and Hylian Shield where they are nearly Indestructable, holds Light power that is the Bane of all Evil, and can be used in a Multitude of ways. the shield can charge up and fire a beam out of it (Similar to Gallantmon's Shield of the Just move from Digimon Season 3) The Sword can charge up and release Beams of light similar to the master sword. and Zero under certain conditions can use the shield to...well surf down mountains or block Devastating attacks like hyperbeams and Explosions. With this weapon being given to Zero by Arceus it also has the power to unleash Arceus' Judgement Attack which is Zero's Ultimate move when using this weapon.
