After a long serch you finally found a way to face Arceus, the most powerful pokemon you know, you are teleported to a sanctuary where Arceus remains on her throne, abusing her power and surrounded by some legendary pokemons (Giratina, Kyogre, Groudon, Palkia and Lugia), you stand confident and Arceus says "Who dares to break into my sanctuary" showing a smile you say "I am here to dethrone you, humanity and pokemons are suffering from your power and I am here to end it" Arceus stands up confident and says "Watch your words mortal, dont you know who I am? I am the mightiest pokemon ever, now you will perish for your misdeeds and disrespect" suddenly several bolt strikes are summoned towards you, they aim to all your vital parts however with a quick move you manage to dodge every one easily, with a graceful movement you unsheate a sword with a strange shape, you quickly strike towards Arceus, the battle seems to be fair, however in one moment you decide to use more power, an aura comes out from you and your speed and strength improves a lot, quickly Arceus seems to be overwhelmed and in a final blow you manage to immobilize her with some light chains, Arceus seems surprised due to the power of the chains, unabling her to use her powers, you stand in front of her sligthly sweating and with a slightly heavy breahing, you say "Its over, I won" Arceus looks at you with a serious expression and she says "Imposible, how did you managed to get so powerful?" you ignore her words and aim your sword towards her, you say "Its over" before you can finish Arceus, Giratina stops your arm, you quickly prepare to attack Giratina but she says "Please, stop it, its over, you dont need to kill any of us, just... hear me, Arceus reign finished, there is no need to continue fighting" the five legendary pokemons swear loyalty to you
