If a [[Monster Card|monster]] is [[Special Summon]]ed from your [[Extra Deck]] by a [[card effect]] , it is not treated as a Fusion Summon, unless stated on the card. For example Special Summoning a monster from your Extra Deck using "[[Cyber-Stein]]" is not considered a Fusion Summon.

Normally, Fusion Monsters cannot be Special Summoned from the [[Graveyard]] or [[Banished Zone]] unless they were properly Fusion Summoned first before being sentthere. You cannot use "[[Re-Fusion]]" to [[revive]] a Fusion Monster that has been Special Summoned using "Cyber-Stein" or sent to the Graveyard by "[[Fusion Guard]]". Fusion Summoned Monsters can be revived using cards such as "Re-Fusion" unless stated otherwise.
