Blue-Eyes Shining Dragon cannot be special summoned except by tributing a Blue-Eyes Ultimate Dragon. There is simply no way around it.
The Hex-Sealed Fusions are 'fusion substitutes' meaning they can take the place of a fusion component for a Fusion Summon. You may use The Light and two Blue-Eyes White Dragons to summon Blue-Eyes Ultimate Dragon, but apart from that, it has no way to combo with Shining Dragon at all.
In gx season 4 it was summoned with future fusion and dragon heart which summoned it immediately from the fusion deck
I'm afraid you are mistaken. Summoned Skull and Meteor Dragon do not fuse. However... Summoned Skull can fuse with Red-Eyes B. Dragon. Their fusion is called "Black Skull Dragon". On the other hand, Meteor Dragon can fuse with Red-Eyes B. Dragon aswell, their fusion is called "Meteor Black Dragon". Black Skull Dragon has 3200 attack points, while Meteor Black Dragon has 3500 attack points. However, Summoned Skull has 2500 attack points where as Meteor Dragon only has 2000. You be the judge on which fusion is better.
No. VWXYZ-Dragon Catapult Cannon can only be Fusion Summoned with its own described method.
As long as the 'Cyber Twin Dragon' was properly summoned initially, by Fusion Summon, and was then destroyed, then yes, you can resummon it from the graveyard with 'Call of the Haunted'. If the 'Cyber Twin Dragon' got to the graveyard by the following methods - sent from Extra Deck by 'Gale Dogra', special summoned but not Fusion Summoned by 'Cyber Stein', or had its Fusion Summon negated, then it cannot be special summoned from the graveyard.
No. A Fusion Monster cannot be summoned from the graveyard unless it was properly special summoned first. Normally this would be Fusion Summon - the only exception are Fusion Monsters who can't be fusion summoned, like the Neos and XYZ fusions. All you need to do for those is follow their text, for them to be properly summoned. Either way, a Fusion Monster placed straight into the graveyard by Fusion Guard cannot ever be special summoned from the graveyard by any method.
yes, if it was properly fusion summoned 1st
Five-Headed Dragon is Fusion Summoned by using any five Dragon-Type monsters as fodder.
No, "Versago the Destroyer" cannot be used as a Substitute-Fusion Material monster in the Fusion Summon of "Cyber Twin Dragon". "Cyber Twin Dragon" specifically states: A Fusion Summon of this card can only be conducted with the above Fusion Material Monsters. This card can be Special Summoned from the Extra Deck using "Cyber-Stein" or "Metamorphosis", but if it is Fusion Summoned, two "Cyber Dragon" cards must be used. The closest you can get to a Substitute-Fusion Material monster for "Cyber Twin Dragon" is if you have "Proto-Cyber Dragon" on the field. (It's card name is treated as "Cyber Dragon" while on the field.)
Not necessarily. In general, it has to be Fusion Summoned, but this doesn't have to be by Polymerization, there are other fusion cards.
No. Special summonable monsters will fall into two categories. Those that say "cannot be special summoned except by" and "Can only be special summoned by" - Synchro, Fusion, XYZ monster belong to the latter category unless their text indicates otherwise (Dark Paladin).The former group can't be special summoned by anything other than the text on their card. For the latter group, if they are special summoned 'properly' first, and then destroyed, they can be revived by cards like Monster Reborn. Even if the former are summoned properly, they can't be resummoned by Monster Reborn.Blue-Eyes Shining Dragon falls into the first category. The only way it can reach the field is from hand, by tributing a Blue-Eyes Ultimate Dragon you control.
No, the text for Cyberdark Dragon says: "This monster cannot be Special Summoned except by Fusion Summon..."
no, dragon master knight can only be fusion summoned.
