The heavenly spirit is called Niko-D, and the personas are the following:

Niko Vazquez runs a FIRE Accent deck, while, like European Voice, his cards have Spanish names in them. His ace is revealed only by its last word, that being Marquez.

Niko Herrmann runs a DARK United deck with him having a German accent. His ace is called "Serpent Evil Dread Dragon" (a retrain of Serpent Evil Dragon).

Niko Vasilev runs a WATER Terrain deck with him having a Russian accent. His ace is called "Crystal Depths Dragon", and his deck makes great use of "Umi" and various "counterparts" that it actually has.

Niko Turkoglu runs an EARTH Annotee deck. He is the youngest of the 9 counterparts, and his ace is called "Imperial Sultan, Osman". His deck gives the Level 1 members effects that copy the effects from other members of different Levels.

Niko Sullivan runs a WIND Order deck, which makes use of monsters being in Primordial State, and his ace is "Data Gale Dragon". His deck is going to be called Datadroid, a subarchetype of the "roid" archetype.

Niko Kobayashi runs a LIGHT Feudal deck, which is centered over the Flow mechanic. It is a deck that focuses on the Surge members having their Levels increased in order to make Flow Summons more effective, and his ace monster is called "Feudal Force Paladin".

Niko Shai runs a TIME column-centered Tactic deck, called Dimensional Spirit, making use of Continuous Trap Cards called "Dimension", paying homage to "Dimension Sphinx", "Dimension Guardian" and "Dimension Mirage". His ace is called "Dimension Spirit Sphinx Guardian Duos".

Niko Foster runs a SPACE Bending deck, based off Australian theme. They utilize Level 4 Trainers and Level 4 non-Trainers, which can escalate their Levels to up to 12, in order to achieve Knot 6 Bending Summons, with the ace, quite ironically, being Knot 8 ("Provocateur Colossal Koala")

Niko Bonaparte runs a MONEY Impact deck, based off stall engines and using protective force to replenish Impact Markers as a shield of your LP. His ace monster is Level 8, that being "Transcation Risk Magician".
