Yes. It's been found out and proven years ago.
Until it's broken of course. I think it works in Versus Battles too but I can't remember.
Ultima Weapon's really only good for beating the final boss really fast. http://www.youtube.com/watch?v=F37fqNGbXIY Otherwise it's terrible, just like every other KeyBlade.
Lexaeus = easiest boss ever.
The only boss I never beat without Dark Mode is Ursula, just because it's an annoying battle and the spin attack really speeds things up when trying to attack her. I don't know if it's just my game, but if I just stay far away from Lexaeus he'll always use RockShatter. So if I ever feel like beating him without Dark Mode I move to the left at the start and keep bashing him with MM Miracles.
Light Dodge Jump is faster/chains more easily and can dodge anything that Riku might have to dodge. Well, maybe not Lexaeus' RockShatter, but that's an easy jump.
Not as cool but it's better/the best for dodging. Too bad his Dark Mode version sucks in this game.
In that case, use Parasite Cage on his Incrementor and then DarkSide on his Sleight Lock, and then just spam Dark Aura!
When in Dark Mode, you can double jump by pressing B and then B again. Pressing A after doing the double jump will make you do the "combo finish". You can see me do this a bit here: http://www.youtube.com/watch?v=PIq3dkeXif0
For some reason I was thinking that he was doing a base AP game, in which Dark Mode wouldn't really be worth it if you can't do Sleights. >_> But if you do have AP upgrades, just dodging/breaking and letting loose OverDrive'd BBAs would probably be more effective.
You might actually want to stay in light mode if you can't use Sleights. This is because light Riku can dodge Dark Aura pretty easily, along with his other attacks.
Lexaeus is the boss that we'll either dominate you or will be utterly dominated. Meaning people that attack him with regular slashes will have a tough time, but people that use Sleights will completely destroy him because of his Physical resistance and Special weakness.
Too bad it still doesn't do as much damage as one hit from a boosted Omnislash. Or a boosted Mega Flare. Or a boosted Holy...
Just make sure you don't give Riku over 100 DP otherwise he won't max out HP or AP. You should also decide now if you want 410 HP/1900 CP Sora or 560 HP/1650 CP Sora (or 560/1900 with 1 Sleight level up, but who really does that?).
Sora's strongest Sleights without using support: Holy = Trinity Limit > OmniSlash > Mega Flare. With support: Holy > OmniSlash > Trinity Limit > Mega Flare. Other noteworthy Sleights: Stopga (just really useful), Curaga (a fast heal), Twinkle (full heal), Blizzard/Fire Raid (dominate bosses), Firaga (dominates bosses), Zantetsuken (just really useful), Blitz (works everywhere decently), Ragnarok (kills any generic Heartless in two hits with Magic Boost). For Riku, anything but Dark Break is just really good.
^ Naminé and Roxas meet during the beginning parts of the game, while Roxas was in virtual Twilight Town. Also, I'd think that Roxas was taken in by the Organization almost right after he was created. This is because Xemnas tells Roxas that he went to see Sora, and it's most likely that he's referring to his Final Mix battle.
I would just not use KeyBlades at all once you get past the first part of the game. Sleights are stronger in general, and then you can always use Items if you're afraid of running out of cards.
By "there" do you mean Castle Oblivion? Why would he be there? You didn't see Xemnas, or Demyx, or the whole other half the Organization. If you mean the game in general though, he does appear in the ending.
I just Stock the cards repeatedly and that gets me to Dark Mode pretty easily. There's also a solid 7, 8, and 9 in there, and even a few 0s. The only decks I don't like are the Atlantica, Twilight Town, and the Destiny Islands decks. Although, all of them have a really easy boss anyways, so I don't care too much about those worlds.
When is there ever a battle in Olympus Coliseum where 3 Dark Auras won't utterly destroy everything? Maybe Hades with low AP, but other than that, I'd have to say that it's one of the stronger decks for Riku.
