No, the 'Neos' fusion monsters state how they must be summoned on their cards. The monsters must be returned from field to deck, you can't summon them like regular Fusion monsters using a fusion card and components in hand.
it is like a polymerization for elemental heroes it only works to summon an elmental hero fusion monster and you can take the fusion material cards(they are the cards needed to make a fusion monster they are listed on the fusion monster) form the graveyard and/or the feild (not hand) don't put them in the graveyard put them in the removed from play pile (this is seprate from the graveyard) and special summon the elemental herofusion monster (this is treated as a fusion summon) ex:elemental hero flame wingman on feild elemental hero sparkman in graveyard use the miracle fusion spell card to summon elemental hero shinning flare wingman and remove from play elemental hero flame wingman and elemental hero sparkman
if you have the necessary cards (fusion materials) in your hand to fusion summon yes, since fusion monsters have their own deck area.
yes
No, cards like 'Polymerization', 'Future Fusion', and 'Fusion Gate' cannot be used to summon any of the XYZ Fusion Monsters. These Fusion Monsters cannot be Fusion Summoned and requires you to banish the monsters listed on the Fusion Monster from your side of the field in order to Special Summon them.
fusion elemental hero absolute zero elemental hero shining elemental hero flame wingman elemental hero great tornado elemental hero giga elemental hero thunder giant
With cards like refusion and instant fusion
cards that specifically state that they cannot be special summoned from the graveyard, like ancient gear golem, or the very limited card: Tyler the great warrior (only one in the world) also an elemental hero fusion
No one card can Special Summon any Fusion Monster. Because some Fusion Monsters specify that they "cannot be Special Summoned except by a Fusion Summon", cards like "Metamorphosis" will not be able to Special Summon them. Even "Instant Fusion" cannot Special Summon Fusion Monsters that state "This card can only be Special Summoned from your Extra Deck by returning the above cards you control to the Deck."
Almost, if not all Elemental Hero Fusions say "This card cannot be special summoned, except by Fusion Summon". This means the only way it can ever hit the field is by Fusion Summon. Some monsters say "can only be special summoned by.." and this listed method is just for the initial summon from hand, if you do this properly, you are allowed to resummon them from the graveyard with cards like Monster Reborn. However, the 'except by' monsters are different, even if you properly special summon them, you still can't revive them from the graveyard like this. Because of that, Elemental Hero fusions are not valid targets for Re-Fusion, as it does not 'Fusion Summon' them.
Elemental hero neos is a normal monster so there for it is not a fusion and no cards combine to make it.
none and it comes with no fusion monsters as well it only has random cards and all he 1st series elemental heroes
'Polymerization' or any similar fusion summon card, or cards that can otherwise special summon Fusion Monsters, like Cyber Stein.
