the hardest boss in kingdom hearts recoded would either be roxas or sora's heartless in it's last form
i think its data roxas
Not the "official" Roxas. Roxas appears as a Data form of himself that was store in Jiminy's journal. He is a hooded figure that appears from time to time and is the final boss.
What boss.
The hardest boss for kingdom hearts is seporathith (sorry bad speller) and he wont be able to take damange from normal attacks and with his abilities your going to need to be at the top of your game it took me 2 days to beat him lvl 81 and all elixers
