Cannot be Normal Summoned or Set. Must be Special Summoned (from your hand) by sending 1 face-up "Elemental HERO Neos" and 1 face-up "Yubel" you control to the Graveyard, and cannot be Special Summoned by other ways. This card cannot be destroyed by card effects. At the end of the Damage Step, if this card battled an opponent's monster: Inflict damage to your opponent equal to the ATK of the monster it battled, and you gain Life Points equal to that monster's DEF.
Elemental HERO Neos and Yubel are both high-leveled monsters so Normal Summoning them would be costly. Luckily both of them have a number of Special Summoning options, Elemental HERO Neos particularly.
It was a fusion damn u konami why did u ruin it :(( , do u know that if it was a fusion then it could be summoned by neos fusion! Which amazing and terrifying itself but still it should be a fusion not a fuckin' monster
