This is the first Union monster in a Generation 5 booster set.
This is the first and only Union monster of the Six Samurai archetype.
This monster is an older, post-mortem version of Legendary Six Samurai - Shinai, according to the Master Guide 3 card storylines.
This is also supported by the fact that both monsters have the same armor, Type, Level, ATK and DEF (barring a difference of 1000 for each).
The Spanish Gladiator's Assault and Turbo Pack: Booster Five prints of this card have a typo, as the word Unión is printed as Union. Its lore (in both cases) uses the correct spelling.

For the effect "Once per turn, you can either: Target 1 face-up "Six Samurai" monster you control; equip this card to that target, OR: Unequip this card and Special Summon it in face-up Attack Position", only one of the effect to equip to a monster and the effect to Special Summon can be activated per turn.: Spirit of the Six Samurai
The monster effect to "Target 1 face-up "Six Samurai" monster you control; equip this card to that target" is an Ignition Effect. It targets 1 face-up "Six Samurai" monster in the player's Monster Zone. (The effect "If the equipped monster would be destroyed, destroy this card instead" is applied while "Spirit of the Six Samurai" itself is treated as an Equip Spell Card. This effect does not make a Chain Link.)
The effect "Unequip this card and Special Summon it in face-up Attack Position" can be activated while "Spirit of the Six Samurai" itself is treated as an Equip Spell Card. (It makes a Chain Link. It can only be activated during the player's Main Phase. It does not target.)
The effect "While equipped by this effect, the equipped monster gains 500 ATK and DEF" is applied while "Spirit of the Six Samurai" itself is treated as an Equip Spell Card. (It does not make a Chain Link.)
The effect "If the equipped monster destroys an opponent's monster by battle: Draw 1 card" is applied while "Spirit of the Six Samurai" itself is treated as an Equip Spell Card. (It activates at the end of the Damage Step in which the equipped monster destroyed an opponent's monster by battle, and makes a Chain Link.)
"A monster can only be equipped with 1 Union Monster at a time" is not treated as an effect.
If the Union Monsters "Protective Soul Ailin" or "Spirit of the Six Samurai" that were Special Summoned face-up on the field by "Celestial Transformation" or "Return of the Six Samurai" etc. are treated as Equip Cards, they are not destroyed during the End Phase. Also, if a Level 5 or lower Fusion Monster is Special Summoned by the effect of "Instant Fusion" but during the End Phase it is treated as an Equip Card, it is not destroyed.: If a Fairy-Type monster Special Summoned by the effect of "Celestial Transformation" is treated as an Equip Card, is it destroyed during the End Phase?
If "Heavy Mech Support Platform" or "Spirit of the Six Samurai" etc. equipped to the opponent's monster is destroyed by the effect of "Ally of Justice Catastor" instead of the equipped monster, and the equipped monster remains on the field, then after that perform damage calculation.: If an opponent's monster cannot be destroyed by the effect of "Ally of Justice Catastor", is damage calculation performed after that?
If "Spirit of the Six Samurai" and the monster it is equipped to would both be destroyed at the same time (by an effect such as "Final Destiny"), the effect of "Spirit of the Six Samurai" being destroyed instead is applied, and the monster equipped with "Spirit of the Six Samurai" remains on the field.: If an equipped "Spirit of the Six Samurai" and the equipped monster would be destroyed at the same time, can "Spirit of the Six Samurai" be sent to the Graveyard instead?
If "Heavy Mech Support Platform" or "Spirit of the Six Samurai" etc. equipped to the opponent's monster is destroyed by the effect of "Ally of Justice Core Destroyer" instead of the equipped monster, and the equipped monster remains on the field, then after that perform damage calculation
The effect of "Spirit of the Six Samurai" that activates when the equipped "Six Samurai" monster destroys a monster in battle begins a Chain at the time when the destroyed monster is sent to the Graveyard.
If a "Six Samurai" monster is equipped with "Legendary Ebon Steed" and "Spirit of the Six Samurai", when the equipped "Six Samurai" monster would be destroyed both the "Legendary Ebon Steed" and "Spirit of the Six Samurai" are destroyed instead.
If both "Spirit of the Six Samurai" and the equipped "Six Samurai" monster are destroyed by the same effect, the "Spirit of the Six Samurai's" effect is not applied.
