"Neo-Spacian" (Ｎ (ネオスペーシアン) Neosupēshian) is an archetype of Level 3 monsters related to the "Elemental HERO" archetype which focuses on the concept of Contact Fusion with "Elemental HERO Neos" to Summon "Neos" Fusion Monsters. In the Yu-Gi-Oh! GX anime, the "Neo-Spacians" along with their infant "Chrysalis" counterparts were introduced by Jaden Yuki, who created the concept of these cards when he was a little boy. There are six "Neo-Spacian" monsters, each with a different Attribute and Type. This theme relies on "Elemental HERO Neos" and was designed to give Jaden an alternate strategy to his "Elemental HERO" monsters. With the exception of "Neo-Spacian Aqua Dolphin", each "Neo-Spacian" monster has the same Type as its "Chrysalis" counterpart.

While the Japanese name of "NEX" is ＮＥＸ (ネオスペーシアンエクステント) and would appear to be part of the archetype, it is not considered a "Neo-Spacian" card due to different superscripting.[1]

Each of the "Neo-Spacians" fused with "Neos"

Unlike most Fusion Monsters, which must be Fusion Summoned, "Neos" Fusion Monsters are instead Summoned via Contact Fusion, which requires shuffling the Fusion Materials on the field into the Deck to Special Summon them. However, the "Neos" Fusion Monsters also have an effect that returns themselves from the field to the Extra Deck during the End Phase. To avoid this, the Field Spell Card "Neo Space" allows the Fusion Monsters to stay on the field as long as "Neo Space" does, and the Equip Spell "Instant Neo Space" allows the equipped Fusion Monster to stay on the field (as well as allowing the Special Summon of "Elemental HERO Neos" when the equipped monster leaves the field). "G.B. Hunter", can also prevent the final effect of the "Neos" Fusion Monsters from applying, but will also stop further Contact Fusions.

The "Neo-Spacian" monsters themselves do not have particularly powerful/useful effects, but there are notable exceptions in the modern game, namely "Neo-Spacian Aqua Dolphin" (which can help the player gain information on the opponent's hand, but also potentially get rid of a combo starter or a problematic hand trap or baiting out the activations of such effects) and "Neo-Spacian Grand Mole" (which can bounce troublesome monsters by battling them). A couple of them ("Neo-Spacian Aqua Dolphin" and "Neo-Spacian Glow Moss") can be upgraded with "NEX" ("Neo-Spacian Marine Dolphin" and "Neo-Spacian Twinkle Moss").

Due to the nature of Contact Fusion, the Deck must use numerous ways to swarm the field with "Elemental HERO Neos" and "Neo-Spacian" monsters. "Neo Space Connector" is essential to this Deck's playstyle as it serves as a one-card "Neos" Contact Fusion; it can Summon "Elemental HERO Neos" or a "Neo-Spacian" monster from the hand or Deck upon its Normal Summon and then it can Tribute itself to Summon another material from the GY. "Neo-Spacian" monsters are also bolstered by many support cards that range from swarming the field with "Cocoon Party", "Contact" or "NEXT" and "Contact Gate". Rather than Summoning the materials onto the field for Contact Fusion, "Miracle Contact" or "Favorite Contact" can return materials from the player's hand, field, or GY to the deck ("Favorite Contact" can also return banished monsters) to Special Summon "Neos" Fusion Monsters, though this does not count as properly Summoning them, so they cannot be Special Summoned again through other cards or effects. "Favorite Contact" also prevents the Fusion Monster from being returned to the Extra Deck if "Elemental HERO Neos" was used.

Most of these effects require filling the GY with "Neo-Spacian" monsters and "Elemental HERO Neos" beforehand. "Convert Contact" and "EN - Engage Neo Space" are viable solutions for this, sending two monsters while also gaining two cards. "Elemental HERO Prisma", which can send "Elemental HERO Neos" or a "Neo-Spacian" monster to the GY and change its name to the one of the sent card can be used for the Summon of a "Neos" Fusion. Other options include using cards like "Wrath of Neos" on it.

"Neos Fusion" is a key card which easily Summons a "Neos" Fusion Monster by sending materials from the Deck to the GY, setting up the GY for either reviving materials for Contact Fusions, or using "Miracle Contact"/"Favorite Contact" in subsequent turns (as the card's activation prevents the player from Special Summoning for the rest of that turn). It can then banish itself from the GY to act as a one-time protection for "Neos" Fusion Monsters from destruction, as well as preventing "Neos" Fusion monsters from being shuffled into the Extra Deck by their own effect if "Neo Space" or "Instant Neo Space" is not on the field. A strong choice to Summon with "Neos Fusion" is "Elemental HERO Brave Neos", which requires a Level 4 or lower Effect Monster and "Elemental HERO Neos", which all of the "Neo-Spacian" monsters are. It also allows other Decks to make use of it as "Neos Fusion" functions similarly to "Foolish Burial" for Level 4 or lower Effect Monsters to make use of their GY effects. Finally, it also does not have an effect to shuffle itself back into the Extra Deck, thereby not needing to waste a copy of "Neos Fusion" from the GY nor requiring "Neo Space" or "Instant Neo Space" to keep it on the field like the other "Neos" Contact Fusions.

Although the effects of "Neo Space Connector" are catered towards the Contact Fusion playstyle as mentioned before, it also generated easy access to the effects of "Neos Fusion" by Special Summoning a "Neo-Spacian" monster through its effect, then using that Summoned "Neo-Spacian" monster and itself to Link Summon "Predaplant Verte Anaconda", which can then activate its effect by sending "Neos Fusion" to the GY to copy its effect.

"Contact Out" acts similarly to "De-Fusion", allowing the user to replace "Neos" Fusion Monsters for its materials in the Deck to save the Fusion Monster from leaving the field or to gain additional attacks.

"Elemental HERO Spirit of Neos" is a key card which can search the vast majority of "Elemental HERO Neos" support cards (or "Polymerization") upon its Special Summon while also tagging itself out for any normal "Elemental HERO" monster from the deck including "Elemental HERO Neos". It can be Special Summoned from the hand by its own effect during the opponent's turn (which allows itself wall out the opponent's attacks) or "Cross Keeper", from the Deck with "EN - Engage Neo Space" or "EN Shuffle". One of the important cards "Spirit of Neos" can search is "Instant Contact", an "Instant Fusion"-like card which can cheat out a Level 7 or lower "Elemental HERO" or "Neo-Spacian" monster from the Extra Deck, allowing additional extensions both within and outside of the "Elemental HERO"/"Neo-Spacian" playstyle.

As the majority of "Neos" Fusion Monsters list specific materials aside from "Elemental HERO Neos", this allows "Neo-Spacian"/"Neos" Decks to make use of cards like "Keeper of Dragon Magic" (for searching out the required "Fusion" Spells, Summoning needed materials from the GY for Contact Fusions while also being a valid material for "Brave Neos") and "Fusion Deployment" (which can Summon any needed materials for "Neos" Contact Fusions while also being searchable by "Keeper of Dragon Magic"). Decks that can pump out multiple "HERO" monsters onto the field, such as the "Vision HERO" engine of "Faris", "Increase", and "Vyon", can utilize "Xtra HERO Infernal Devicer" to search out "Elemental HERO Neos" and/or "Neo-Spacian" monsters.

As all main deck "Neo-Spacian" monsters are Level 3 and have completely different ATK, Types and Attributes, while only "Neo-Spacian Dark Panther" and "Neo-Spacian Flare Scarab" have the same DEF, any Deck playing a heavy amount of "Neo-Spacian" monsters is capable of using "Small World" to search any of their key monsters, such as "Neo Space Connector" or "Keeper of Dragon Magic".

While the original purpose of the "Neo-Spacians" is to Contact Fusion with "Neos", with cards like "Convert Contact", "Cross Porter" and "Space Gift", they've become an interesting Draw Engine, Deck Thinner and Graveyard Filler disregarding "Neos".

The "Chrysalis" archetype could help in this, but they are very likely to be dead draws, so it's usually better just to avoid them.

"Convert Contact" is the key card, thinning your Deck by 3 cards and sending two monsters to the Graveyard (one of your choice) without making you lose hand advantage. The other key card, "Cross Porter" can be used to keep hand advantage, as it can be easily sent to the Graveyard with cards like "Armageddon Knight", "Foolish Burial" or "Dark World Dealings". If revived (even with cards like Junk Synchron), it can provide an extra Neo-Spacian.

Once in the Graveyard, these monsters can then be used for different purposes, like the Special Summon of "Dark Simorgh"/"Chaos Sorcerer" or using cards like "The Beginning of the End". Since both "Cross Porter" and "Armageddon Knight" are low-level DARK Warrior monsters, and there is one DARK Neo Spacian and one Warrior Neo Spacian, cards that support DARK monsters (like "Dark Eruption"/"Allure of Darkness") and Warrior monsters (like "Reinforcement of the Army") work quite well.

The first known competitive Deck to use this Engine was Junk and Debris Deck.

The main weakness of the "Neo-Spacians" is that their Fusion Monsters return to the Extra Deck during the End Phase of the turn. Relying on Field and Equip Spell Cards to keep monsters on the field can be easily thwarted with cards such as "Dust Tornado" and "Mystical Space Typhoon". This is somewhat mitigated with the "Neos" Fusion Monsters that require three materials as they have powerful effects that activate when they return to the Extra Deck. "Contact Gate" also helps by Special Summoning a "Neo-Spacian" when the monster returns but this only goes part of the way to solve the problem. The main way around this flaw is by using "Contact Out" to Special Summon the specific Fusion Materials listed on the card so that you can hit your opponent for more damage or Contact Fuse something different. Alternatively, you can banish "Neos Fusion" from your GY to prevent the monster from going back into the Extra Deck. This effect can also be used to protect the monster from battle and destruction effects, similar to "Return of the Dragon Lords".

"Neo-Spacians" are fairly weak on their own, with no specific support cards. Since "Elemental HERO Neos" is a Level 7 Normal Monster, specific cards to Summon it are needed such as "O - Oversoul", "Neo Space Connector" or "NEXT".
