 "'''Neo-Spacian'''" ({{Ruby|Ｎ|ネオスペーシアン}} ''Neosupēshian'') is an [[archetype]] of [[Monster Card|monsters]] related to the "[[Elemental HERO]]" archetype which focuses on [[Contact Fusion]] with "[[Elemental HERO Neos]]". In the ''[[Yu-Gi-Oh! GX]]'' anime, the "Neo-SpaciansSpacian"monsters, along with their infant "[[Chrysalis]]" counterpartsforms, were introduced by [[Jaden Yuki]], who created the concept of these cards when he was a little boy. There are six [[Level]] 3 "Neo-Spacian" monsters, each with a different [[Attribute]] and [[Type]]. This theme archetype relies on "Elemental HERO Neos" and was designed to give Jaden an alternate strategy to his "Elemental HERO" monsters. While the Japanese name of "[[NEX]]" is {{Ruby|ＮＥＸ|ネオスペーシアンエクステント}} and "[[NEXT]]" is {{Ruby|ＮＥＸＴ|ネオスペースエクステンション}} and they would make it appear to be part a member of the archetype, they're it is not considered a "Neo-Spacian" card due to "different superscripting".<ref>[httphttps://yugiohwww.faqdb.konamiyugioh-card.jpcom/yugiohdb/EokpControlfaq_search.action?&langope=en4&tidcid=398477162&eventrequest_locale=FE0006 Konami FAQ]: Can ja</ref> Similarly, the effect of "Convert ContactNeo-Spacian" send monsters themselves are not to be considered as "NEX[[Neos]]" cards according to the Graveyard?</ref>a ruling for "[[Elemental HERO Divine Neos]]".==Membersand related cards=={| class="wikitable"style="text-align:center"! rowspan="2" | [[Attribute]]

==Playing style=="[[Elemental HERO Spirit of Neos]]" is a key card which can search the vast majority of "Elemental HERO Neos" support cards or "[[File:ElementalNeosPolymerization]]" 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 to wall out the opponent's attacks, or "[[Cross Keeper]]", from the Deck with "EN - Engage Neo Space" or "[[EN Shuffle]]".jpg|200px|left|thumb|Each 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 which can easily Summon: the two-material "Neos"Contact Fusions, "[[Neo-SpaciansSpacian Marine Dolphin]]" fused with (as an easier way to Summon "[[Elemental Hero Neos (anime)|HERO Marine Neos]]") and other important "Elemental HERO" Fusion Monsters such as "[[Elemental HERO Sunrise]]". Above all else, it functions as a useful extender both within and outside of the "Neos"/"Neo-Spacian" playstyle.

Unlike most Fusion Monsters, which must be [[Fusion Summon]]edOver time, later support for the "Neo-Spacian"/"Neos" Fusion Monsters are instead Summoned via [[Contact Fusion]], which only requires the [[Fusion Material]]s playstyle started to be focus more on the [[field]]. However, the "Neos" traditional Fusion Monsters also have an effect Summon playstyle that returns themselves from the field to the [[Extra Deck]] during the [[End Phase]]. To avoid this, the [[Field Spell Card]] other "[[Neo Space]]Elemental HERO" allows the Fusion Monsters to stay on the field as long as "Neo Space" does, monsters (and the [[Equip Spell Card|Equip Spell]] "[[Instant Neo Space]]" allows the [[equip]]ped 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). The Monster Cardare notable for, "[[G.Bintegrating the two themes' playstyles together more easily. Hunter]]"As such, can also prevent the final effect of the remaining "[[Neos]]" Fusion Monsters from applying, but will also stop further Contact Fusions. There are the 6 primary "Neos" required to be Fusion Monsters, 3 Summoned by Triple instead of Contact Fusions ("[[Elemental HERO Magma Neos|Magma]]", "[[Elemental HERO Storm Neos|Storm]]" and "[[Elemental HERO Chaos Neos|Chaos]]"), and 1 requiring a Fusion Material Summoned with "NEX" ("[[Elemental HERO Marine Neos|Marine]]"), for a total of 10.:

* "[[Elemental HERO Divine Neos]]" is difficult to Summon due to its Fusion Material requirements, though it can banish a "Neos", "Neo-Spacian" monsters are or "HERO" monster to permanently gain ATK and temporarily copy the banished monster's effect.* "[[Elemental HERO Neos Knight]]" is a formiddable beatstick that can attack twice although it cannot deal battle damage.* "[[Elemental HERO Brave Neos]]" is a very flexible "Neos" Fusion Monster with a variety of useful effects whilst being easy to Summon, only requiring a [[Level]] 4 or lower [[Effect Monster]] and "Elemental HERO Neos". Also, it also bolstered does not have an effect to shuffle itself back into the Extra Deck, thereby not requiring "Neo Space" or "Instant Neo Space" to keep it on the field. Furthermore, if "Brave Neos" destroys a monster by many battle, it can search for an "Elemental HERO Neos" support card. * "[[Elemental HERO Shining Neos Wingman]]" can destroy the opponent's cards that range from swarming on the field with upon Summon whilst having destruction protection effects. One of its commonly used materials, "[[Elemental HERO Flame Wingman - Infernal Rage]]", can search "Favorite Contact" which can Special Summon "Shining Neos Wingman" during the opponent's turn to disrupt their plays. * "[[Elemental HERO Neos Kluger]]" can float into "[[Neos Wiseman]]" upon destruction, which can be used for strategic OTKs.* "[[Cocoon PartyRainbow Neos]]" and boasts a 4500 ATK beatstick which can clear the opponent's field or GY. * "[[ContactArmed Neos]]"can destroy multiple monsters upon its Summon, then Tribute itself to upgrading them with cheat out an "NEXElemental HERO"Fusion Monster during the opponent's turn if it destroyed an opponent's monster by battle on the previous turn.

A good card to include is "[[Elemental HERO PrismaNeos Fusion]]". It can send is an important card which easily Summons a Fusion Monster that requires two materials including "Elemental HERO Neos" monster by sending those materials from the field, hand or Deck to your the GY (even [[GraveyardIgnoring the Summoning conditions|ignoring its Summoning conditions]] and have its own name treated as ). This sets up the GY for either reviving materials for Contact Fusions, "Miracle Contact" or "Elemental HERO NeosFavorite Contact"in subsequent turns (as the card's activation prevents the player from Special Summoning for the rest of that turn). You It can then use it 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 Summon of a Extra Deck by their own effect if "Neo Space" or "Instant NeoSpace" is not on the field. This cards greatly supports easier access to the two-Spacian material "Neos" Contact FusionMonsters, as well as most of the aformenetioned "Neos" Fusion Monsters that must be Fusion Summoned, or and protecting said monsters. Other Decks can make use cards like of "Neos Fusion" to Summon "Brave Neos" similarly to a "[[Wrath of NeosFoolish Burial]]" on itfor Level 4 or lower Effect Monsters to make use of their GY effects later.

===Other additions===To alleviate the need of specific materials that "Neos" Fusion Monsters requires, the Deck can make use of "[[Miracle ContactKeeper of Dragon Magic]]" is (for searching out the Neo-Spacians' best cardrequired "Fusion" [[Spell Cards|Spells]], as it Summoning needed materials from the GY for Contact Fusions while also being a valid material for "Brave Neos") and "[[Fusion Deployment]]" (which can access your hand, your side Summon any needed materials for "Neos" Contact Fusions while also being [[search]]able by "Keeper of Dragon Magic"). Decks that can pump out multiple "HERO" monsters onto the field, or your Graveyard for such as the monsters you need to "[[Vision HERO]]" engine of "[[Special SummonVision HERO Faris|Faris]] your "Neos, "[[Vision HERO Increase|Increase]]" Fusion Monsters (however, any monster Summoned by and "Miracle Contact[[Vision HERO Vyon|Vyon]]" do not count as having been properly summoned, so they cannot be Special Summoned again through other cards or effects). can utilize "[[Contact OutXtra HERO Infernal Devicer]]" is especially useful in avoiding card effects that force your to search out "Elemental HERO Neos" and/or "Neo-Spacian" monsters to leave have them in hand or in the field GY (ie. after using them for a Fusion Summon of a monster such as those of your own "Brave Neos" monsters), or can allow in preparation for multiple attacks if your opponent controls 1 "Miracle Contact" or no "Favorite Contact". However, the player should note that a few cards that support the "Neo-Spacian"/"Neos" playstyle ("EN - Engage Neo Space", "Fusion Duplication", "Keeper of Dragon Magic" etc.) prevents the player from Special Summoning non-Fusion Monsters from the Extra Deck (cutting off access to the [[Link Monster]] plays such as the aformentioned "Infernal Devicer"). Likewise, the effect of "Infernal Devicer" prevents the player from Special Summoning non-"HERO" monstersfor the turn (thus preventing the Contact Fusion playstyle), so the player will have to choose one strategy and decide their plays accordingly.

"[[Elemental HERO Neos Alius]]" is a [[Gemini monster]] whose effect allows him to be treated as if his name was "Elemental HERO Neos." This is very useful in a As all Main Deck "Neo-Spacian" Deck, as it gives you the option of having more than three "Neos" to use in Contact Fusion. It is also a monsters are Level 4 monster with 1900 [[3 and have completely different ATK]]. Given that "Neos Alius" is a Gemini monster/DEF values, Types and Attributes, he can be supported by cards like while only "[[SuperviseNeo-Spacian Dark Panther]]" and "[[Gemini SparkNeo-Spacian Flare Scarab]]". One popular strategy is to stick exclusively to have the most useful same DEF, any Deck playing a heavy amount of "Neo-SpaciansSpacian": monsters is capable of using "Dark Panther[[Small World]]"to search any of their key monsters, such as "Grand MoleNeo Space Connector", or "Air Hummingbird" and "Flare ScarabKeeper of Dragon Magic".
