Again this section will seem to swim by, so after you gain the Key of Beginnings, head to the crown door to face off against Ursula.
Boss Battle: Ursula
Again, this witch is nothing to be afraid of. She still uses her tentacles as a barrier so that you must defeat them first. However, if you can use D Mode, you can make short work of those useless appendages.
Ursula still shoots bubbles out of her mouth, so be sure to dodge those intently, since they cause your controls to act upon the reverse order (forward becomes backwards, left becomes right, and so on).
After you defeat Ursula, you gain the Ursula Card and level up. Now it is time to move on to Olympus Coliseum.
Back at Castle Oblivion, things take a turn for the dark side as Zexion, Lexaeus, and Vexen discuss what is to be done. Riku Replica appears, however he does not get the welcome he was hoping for. Vexen sizes him up and realizes Riku Replica could be of greater use if Naminé messes with his memories as well. Riku Replica gets quite confused and brings a feeling of guilt and sorrow when the Organization forces him against his will to be “more like Riku”. He is forced against his will to have his memories filled with false ones, and is none too pleased about it.
