In the Anime the Phoenix Mode worked as follow:
During either player's turn, you can pay 1000 Life Points to transform "The Winged Dragon of Ra" into its Phoenix Mode. Until the end of the turn this effect is activated, the ATK and DEF of this card are reduced to 0 (The ATK and DEF of this card return to their respective values prior to this effect's use) and it gains the following effects: ● This card cannot be destroyed by battle, and you take no Battle Damage from battles involving this card. ● This card cannot be targeted and is unaffected by the effects of other monsters, Spells, and Traps. The effect of "The Winged Dragon of Ra" only affects this card for one turn.
