Kingdom Hearts II Is it possible

Is it possible to even fight the Enigmatic Knight on any other than Proud or Critical? I have beaten Proud and Critical without seeing his portal once but I notice videos of people only with Proud and Critical...Can you fight him on anything except those two? Like Standard or Beginner? I actually just want to see the portal but never do and get tired of wondering why

Well I just wish I knew how.....I have all drives maxed out, the summon is maxed out, I have completed 2/6 puzzles, I'm lvl 65, I've beaten all of Org. XIII, I've beaten all tournaments except the Paradox ones, I've beaten 2/13 of the mushrooms (I avoided them at first)

So I wonder if any of the stuff missing above changes it.....I really want to fight him...Since he is tougher than Sephiroth it'd make me happy to see how tough he really is when I fight him...I also want to fight the rest of the Org. XIII re-fights.....I got Xaldin, Vexen, Lexaeus, Zexion, Axel, Demyx, Marluxia, and Larxene.....

Now that I think of it.....I ask to many questions...

Oh so they changed that.....So you can beat the game and continue from it? I would normally stop after beating the boss because I thought that was it...Hopefully that'll work
