The card you are thinking. The fusion between "Slifer the Sky Dragon", "Winged Dragon of Ra", and "Obelisk the Tormentor" is called "The Creator of light, Horakhty".
Slifer's only protection is that spell, trap or monster effects cannot be used in response to his summon, meaning he is safe from cards that specifically respond to summons, such as Torrential Tribute. After that, targeted traps can be freely used against him.
Obilisk the Tormentor, Slifer the Sky Dragon, and Wing Dragon of Ra.
Slifer the Sky Dragon is a God and has no code. If you are playing on the PSP get the Yu-Gi-Oh tag force 1 and it will allow you 3 copies of the Slifer card.
The Winged Dragon of Ra is it's at The Final Boss card shop and maybe Slifer as well
There is currently no game-legal print of Slifer the Sky Dragon. Obelisk has a TCG and OCG print, Ra has an OCG print, so there will eventually be a legal Slifer.

Yugi received Slifer the Sky Dragon from Strings per the guidelines of the tournament that each Duelist must ante their most valuable card.

The current game-legal text for Slifer the Sky Dragon says "When Normal Summoned, cards or effects cannot be activated" This prevents the activation of Bottomless Trap Hole in response to Slifer's Normal summon. However this is only for Normal Summon. Slifer can be Special Summoned, and if Special Summoned, then his continuous effect will apply as normal, before cards that respond to summons can be activated. That means if he is special summoned, and his ATK goes to 2000, the summon can be responded to by Bottomless Trap Hole, he will be destroyed and removed.
