Kairi and Riku are flying their Gummi Ship together trying to find new worlds inside the Kingdom Hearts Universe.

"Riku, look up ahead." Kairi says pointing.

"That World is called the Darkwing Duck City, King Mickey's Computer Map shows it as being unexplored, we must be the first ones to discover it since the Heartless invaded Kingdom Hearts... I'm landing." Riku explained while working the Gummi Ship's Controls.

After hiding their Gummi Ship to avoid someone stealing it, Riku and Kairi looked around the City Streets for themselves.

Splatter Phoenix and Taurus Bulba laughed together as Darkwing Duck was being chased around their Abandoned Warehouse by the Shadow Heartless.

Once the two Keyblade Heroes noticed the Shadow Heartless attacking the Crowbar Swinging Launchpad McQuack, they charged the enemies to save him.

"Whoever you are, help me!" Launchpad McQuack screamed panickingly while defending himself from the Shadow Heartless with the Crowbar being his only weapon.

Launchpad McQuack dodged the claws of the Shadow Heartless and continued defending himself with the Crowbar as the two Keyblade Heroes joined the fighting.

"There has to be something that will stop these things!" Darkwing Duck yells while running upstairs from the Shadow Heartless Swarms chasing after him.

"I must keep running towards the rooftop and hope that Launchpad McQuack has called the Justice Ducks together to rescue me!" Darkwing Duck Proclaimed to himself frantically.

"I think these Heartless Creatures will 'Destroy Darkwing Duck' for us." Splatter Phoenix remarked as they watched about 60 Shadow Heartless chasing Darkwing Duck upstairs and then she started the Evil Laughing with Taurus Bulba right beside her.

"Thank you for saving me... we must find DW before these things do!" Launchpad McQuack proclaimed before running towards the Abandoned Warehouse where Darkwing Duck went earlier.

Kairi and Riku followed Launchpad McQuack as he found out that Taurus Bulba's Warehouse was swarming with the Heartless Creatures from the Kingdom Hearts Universe.

Several of the Soldier Heartless and the Shadow Heartless converged on the Keyblade Heroes as the new conflict began all around them.

"Thunder... Cure... Fire!" Riku yelled his Basic Magic Commands as his Keyblade automatically responded to his voice and activated the Old Magic Spells that Yen Sid Incorporated into their Keyblades from Sora's Keyblade hopeful that it would be enough to protect them when they took over for Sora inside the Kingdom Hearts Universe fighting the Heartless Creatures by themselves.

Kairi was fighting the Heartless inexperienced with how to use her Keyblade while Riku took charge protecting Launchpad McQuack from the hidden danger of the Heartless Swarms coming after them.

Together they searched for Darkwing Duck and fought the Heartless Swarms getting in their way.
