Since I had no clue which incarnation of Annihilus they were talking about I am going to have them go through several different fighting scenarios, each of which are to be considered as separate battles happening in separate times and separate places.
The first four scenarios all take place in Las Noches, the Arrancar stronghold which resides in the realm of Hueco Mundo and the last four scenarios take place on Annihilus' homeworld of Arthos in The Negative Zone.
Scenario One: This is a random encounter for both Ulquiorra and Annihilus. Annihilus only has The Cosmic Control Rod and neither combatant has prep time.
Scenario Two: For Annihilus this is a random encounter. Ulquiorra on the other hand is well aware that Annihilus is coming. Ulquiorra has prep time, Annihilus does not. Like before Annihilus only has The Cosmic Control Rod.
Scenario Three: Take Scenario Two and reverse the positions I put Ulquiorra and Annihilus in.
Scenario Four: Both combatants have prep time. Again, Annihilus only has The Cosmic Control Rod.
Scenarios Five through Eight: They are essentially the same Scenarios as before except Annihilus has both The Quantum Bands and The Cosmic Control Rod.
Scenario Nine through Twelve: Same situations as before except Annihilus does not have either The Quantum Bands or The Cosmic Control Rod.
So...could you guys all help me to end this argument between my friends once and for all by giving me a definitive answer to this question? I'd really appreciate it.
P.S.: In case this ends up being seen by members of the AnmeVice Community as a spite thread then I just want to apologize in advance for making it, I am just trying to end an argument that has been going on for too long.
