After entering [[Castle Oblivion]], Ansem manipulates the [[darkness]] in Riku's heart, giving Riku the ability to use Dark Mode freely. In this form, Riku can use his darkness without the worry of being taken over by Ansem. Since Riku has a strong affinity to darkness, this form gives him a substantial advantage in battle, such as increased speed and feeding the [[Soul Eater]]'s unique power-up ability with the power of darkness. The [[Riku Replica]] can embrace the darkness willingly, thus he can also use and stay in Dark Mode.

[[Vanitas]], one of the main antagonists of ''[[Kingdom Hearts Birth by Sleep]]'', as well as the [[Vanitas Remnant]], wears a bodysuit similar to the one Riku wears while in Dark Mode. Under [[Ventus-Vanitas|Vanitas's possession]], [[Ventus]] also wears this suit.

{{Q|The darkness will destroy you.|Riku upon entering Dark Mode for the first time.}}

Riku fled injured and severely weakened through a [[Corridor of Darkness]] back into the heart of the castle, where he reverted to his normal form. There, he met a hooded Ansem, who persuaded Riku to open his heart to darkness. The enigma possessed Riku, and used his body, now permanently in Dark Mode. In this mode, he created and wielded the [[Keyblade of heart]], which he used to unlock Maleficent's true darkness. He waited and watched as Maleficent fell at Sora's hand, allowing Ansem to claim [[Kingdom Hearts]] as his own. All he needed was the heart of the last [[Princesses of Heart|Princess of Heart]], which resided within Sora. He attacked the Keyblade wielder, but was defeated. Riku used the last of his strength to fend off Ansem as Sora released his own heart to free [[Kairi]]'s heart.

[[File:Reunion with Riku 02 KHRECOM.gif|thumb|250px|Riku Replica entering Dark Mode.]]

After his re-encounter with Ansem in [[Castle Oblivion]], Ansem tempered Riku's darkness, activating Dark Mode once again. Riku would utilize this form as he struggled in the card worlds. He would change into Dark Mode sparingly, a massive fear of the darkness manifesting in the depths of his heart, much to Ansem's displeasure.

Later on, [[Vexen]], [[Lexaeus]], and [[Zexion]], members of [[Organization XIII|the Organization]], wished to use the boy and his dark powers to halt the plans of the traitorous [[Marluxia]]. When Vexen challenged Riku, it was his immense power that led to the creation of the [[Riku Replica]], an aggressive replica of Riku created by Vexen from the boy's combat data. Ansem seized the replica as an opportunity to use it as a model for Riku, urging him not to fear the dark like the fake.

Eventually, Riku came before Lexaeus. A battle ensued between the two, Ansem possessing Riku's body in order to do away with the [[Nobody]]. Riku's sudden recollection of Ansem's control almost allowed Ansem complete control over his body. Were it not for [[Mickey Mouse|King Mickey]], Ansem's plan to get Riku back under his control would have succeeded.

In the [[Twilight Town]] card world, Riku was approached by [[Ansem the Wise|DiZ]], the bandage-faced man telling him to seek out Naminé. He battled his replica a final time, meeting up with Naminé at last. She offered to put him to sleep so she could lock his heart, freeing him from Ansem and the consequences Ansem had on Riku's heart. Riku refused, needing his power to finish Ansem for himself. It was then Riku headed towards his final battle in Castle Oblivion to face Ansem for the last time. Afterwards, Dark Mode is never used by Riku again.

[[Data-Riku]] is shown to be able to use Dark Mode after he is infected by the [[Bug Blox]].

===''Kingdom Hearts III''===

Riku Replica appears in Dark Mode whenever he appears to the real Riku. Although [[Dark Riku]] and Vanitas are initially seen wearing the same black coats as the other Seekers of Darkness, they don their Dark Mode bodysuits during their clashes against the Guardians of Light.

In ''Kingdom Hearts Birth by Sleep'', Vanitas's suit is colored in various shades of blacks and reds rather than blacks and violets, a distorted version of the Unversed insignia appearing on Vanitas's chest rather than the Heartless insignia-like emblem that appears on Riku's while in Dark Mode. The Vanitas Remnant uses the same suit, but it is black and white instead of black and red.

In ''Kingdom Hearts Chain of Memories'' and ''[[Kingdom Hearts Re:Chain of Memories]]'', since Riku is a playable character, he has a specific moveset while in Dark Mode, along with additional sleights.  

Dark Mode is only triggered when the player manages to fill up the Dark Points gauge up to 30 by either breaking cards or taking damage{{?}}<!--Does this work exact the same way as Riku losing DP while in Dark Mode for CoM and ReCoM distinctively?--> and while having any card(s) in use at that time. If Riku takes a Card Break, he loses DP and cannot enter Dark Mode, even if he was going to do so.  

Whether Riku is in Dark Mode or not, he loses a certain amount of Dark Points if his card is broken, with the game displaying along with the "Cardbreak" text how many DP are earned or lost. The number of Dark Points lost is equal to the difference between the enemy's card and the broken card. For example, if an enemy breaks Riku's 2 card with a 9 card, Riku loses 7 DP. Additionally, if a sleight card breaks Riku's single card, the total value of the sleight is taken into account when calculating the difference between the sleight and the broken card, but with a maximum amount of 9 DP for Riku to lose. The same calculation is applied when Riku gains DP when he breaks cards while not in Dark Mode, and gains 5 additional DP from performing a Rapid Break, where he can gain up to 14 DP with a single Rapid Break.

{{Main|Game:Riku|Game:Riku Replica|Game:Dark Riku}}

During the first battle with Riku's Dark Mode in ''Kingdom Hearts'', he uses supreme agility to jump far distances, either away from or towards Sora's location. While Sora is in close range, Riku will attempt a powerful spin-slash. He can also perform a single slash before following it up with a rushing slash, and he is also able to deal immense damage. Magic has no effect on Riku, so the player must rely solely on the Keyblade. Jars can be found on the sides of the battlefield which contain HP Orbs and Hi-Potions.

When tackling a possessed Riku, who wields Dark Mode to its maximum potential via Ansem, one must take extreme caution. Riku will dodge almost every hit, attacking with just as much speed. Guard and retaliate immediately afterwards. Depending on what attack is blocked, a certain number of Tech Points may be earned. As his HP dwindles, Riku will begin to empower himself further with Darkhand state, gaining new abilities and adding additional properties to his old abilities. His dash attack fires Shock Slashes that can be blocked back to him, and he can use Helm Split to perform a jump attack that fires bursts of darkness from the ground and ends Darkhand state. Eventually, he will also gain the ability to use Dark Aura, and when he reaches his final HP bar, he will stay in Darkhand state permanently. Again, magic has no effect, the Keyblade and its abilities the player's only chance of survival.

When fighting the Riku Replica in ''Kingdom Hearts Chain of Memories'', he attacks in a fashion comprised of a two-hit combo that stuns on the second hit. He also uses a jump-attack that causes flames to burst from the Soul Eater. Over the series of four battles, the Riku Replica gains access to Sleights, each very powerful and threatening to the player's HP Bar.
