They are treated as Effect Monsters. You can Normal Summon them either by Tributing 3 monsters/tokens or by a card effect. (they can't be Set). The Normal Summoning of them can't be negated. On the turn they are Normal Summoned they are immune to card effects that Tribute. The controller of them can change their Battle Position once. If they are Special Summoned from the Graveyard or out of play they are sent to their controller’s Graveyard or Removed From Play area during the End Phase. If they are Special Summoned in face-up Defense Position when a monster your opponent controls declares an attack or activates a card effect that targets 1 of your monsters switch the target to them. While face-up on the field they are immune to card effects that negate their attacks, destroy them, return them to their controller’s hand/deck & change their control/type/attribute/Battle Position except their own effects or the effects of other DIVINE monsters. Card effects that alter their ATK & DEF Points can only affect them for the remainder of the turn (Afterwards their ATK & DEF Points return to their original value from when they were Summoned). Any Equip Cards that target them are destroyed immediately. All activated Continues Spell & Trap Cards that designate them as the target are destroyed at the end of the turn they were activated.

If the ATK or DEF is decreased to 0 destroy the monster(s). The controller of “SLIFER” can't do anything until “SLIFER'S” effect resolves.

After his effect resolves the controller of “SLIFER” can still declare an attack with him if it is their turn.

The Hidden Powers of Obelisk or Fist of Fate: Once per turn you can tribute 2 monsters you control to increase “OBELISK'S” ATK & DEF Points to infinite. You can then either have “OBELISK” destroy all monsters on you opponent's side of the field & if all your opponent's monsters are destroyed inflict 4000 points of damage treated as Battle Damage to your opponent’s Life Points. Or alternatively have him attack all your opponents monsters (once each) & inflict 4000 points of damage treated as Battle Damage to your opponent’s Life Points. Also the difference between his original ATK Points (4000) & your opponents Attack Position monster's ATK Points is taken away from your opponent's Life Points). You can't declare an attack with him the turn you activate this effect. Also you can't activate this effect the turn you declare an attack with him
Fist of Fury: Tribute “SLIFER” & “RA” to increase “OBELISK'S” ATK & DEF Points to infinite, destroy all monsters on you opponent's side of the field & and inflict 4000 points of damage treated as Battle Damage to your opponent’s Life Points.

THE WINGED DRAGON OF RA
You can also recite the Ancient Chant below when Normal Summoning RA
Almighty Protector of the Sun and Sky. I beg of thee Please heed my cry.
Transform thyself from Orb of Light and bring me victory in this fight.
I beseech thee grace our humble game. But first I shall CALL OUT THY NAME! WINGED DRAGON OF RA!
While RA is face-up on the field he gains ATK & DEF Points equal to the ATK & DEF Points of the tributed monsters.
While RA is face-up on the field he is treated as a Machine-Type monster.
Egyptian God Phoenix: You can choose to activate this effect when Special Summoning “RA”. When this effect is activated “RA” is immune to all card effects, he can't be destroyed by battle & you take 0 Battle Damage from battles with this card. Pay 1000 LPs to have “RA” attack 1 of your opponent's monsters (even when he is in DEF Position). The Attack target is automatically destroyed without applying Damage Calculation. You can't declare an attack with him the turn you use this effect
Instant Attack: You can only activate this effect when “RA” is Special Summoned without activating his “Egyptian God Phoenix” effect. “RA” can attack instantly (even when a card effect has been activated that prevents him from attacking) & attacks all monsters your opponent controls (once each). If all your opponent's monsters are destroyed he can attack your opponent directly, even if he has already attacked one or more times this turn.
Point To Point Transfer: Pay all but 1 of your Life Points & tribute any other monsters you control to increase “RA'S” ATK & DEF Points by the amount of Life Points paid & the combined sum of the ATK & DEF of the tributed monsters. If “RA” were to be banished/removed from play or your Life Points were to reduce to 0 by card effect or Battle/Direct Damage or an opponent's monster effect that allows it to attack you directly after you have activated this effect reduce “RA'S” ATK & DEF Points to 0 to gain Life Points equal to “RA'S” total ATK Points & negate the direct attack effect. If you use this effect after you attacked with “RA” his attack is negated. You must wait until your next turn to reactivate this effect. You can't use this effect if you activate “RA'S” Egyptian God Phoenix effect.
The Rage Of Ra: This effect can only be activated once per turn. Pay 1000 LPs to destroy all monster on your opponent's side of the field.
When OBELISK is summoned at the same time as SLIFER & RA you can activate the following effect.
Titan Firestorm: When this effect is activated it can't be negated, your opponent can't activate any card effects & OBELISK can attack instantly (even when a card effect has been activated that prevents him from attacking). Equip SLIFER & RA to him to increase his ATK and DEF Points to infinite (they are not treated as Equip Cards). When SLIFER is equipped all your opponent's Spell & Trap cards on the field are destroyed. When RA is equipped all your opponent's face-down monsters are flipped face-up and all their monster's effects are negated. OBELISK then attacks all of your opponent's monsters (once each). When he declares an attack respective to the Battle Position of the attack target, reduce your opponent's Life Points to 0. (as this effect was not used until near the end of Yu-Gi-Oh! Pyramid of Light & Anubis only had Theinen the Great Sphinx on the field this is what I think the full effect is).
