Opening

BGM-Rockman. EXE Stream OST-Be Somewhere by Buzy (Opening Ver.)

The opening starts off as a split screen, with an image of Spider-Man on the left standing in the middle of New York City, and an image of Mega Man X on the right standing in the middle of Abel City. Both heroes slowly open their eyes simultaneously before firing their respective weapons, a web shot and a charged shot, at the screen before the title appears:

D-Avengers: The X Factor

The next couple of scenes is a roll call of the pair of the main characters: Sonic the Hedgehog and Knuckles the Echidna posing side-by-side in one shot, Blake Belladonna and Yang Xiao Long performing the same in the next shot, Spider-Gwen and Penny Polendina as well next, and lastly Zero and Axl.

The scene immediately shifts to a shot of a massive Ultron army tearing through New York led by the original glowing eyes of Ultron Prime. In Abel City, hundreds of Mechaniloids and Mavericks from the past like Chill Penguin and Neon Tiger are wrecking the city while the Maverick King, Sigma laughs on a rooftop while enjoying the destruction. On top of Avengers Towers, the main team of Avengers led by Captain America stand tall and proud, then swiftly shifts to Maverick Hunter HQ with Alia and Commander Signas, with a hologram of Doctor Light appearing beside them.

Standing on the grassy plains next to New York, a maskless Peter Parker raises his hand to the nightly sky to reach for the moon but it's too far away. He sees the daunting image of Doctor Doom holding the Exo Chaos Stone in front of the moon, and then the unsettling smirk of Salem grasping the Exo Nether Stone appearing after him. But above the moon, in space, a large and dark silhouette of Ultron Sigma has his mechanical hands on the new pink Exo Stone. Seeing this, Peter puts on his mask and wears a brand new suit with a web cape flaunting behind him (he's wearing the "Unlimited Suit" from the old cartoon, Spider-Man Unlimited) and gets ready to fight.

In Abel City, Spider-Man points his D-Avengers to fight what appears to be robotized Avengers. Sonic speeds pass the corrupted Wasp's stingers while running up the leg of the giant mecha Yellowjacket. Spider-Gwen is seen swinging away from Hawkeye's arrows while Penny uses her floating swords to counter Iron Man's repulsors. Blake backflips from Scarlet Witch's hex bolts. Knuckles hops over Thor's hammer before barely catching the Hulk's gamma fist. Yang and Captain Marvel's hairs start to glow with power before they both collide their fists, resulting in a massive explosion. Through the smoke, a webline hits the ground to reel in Spider-Man as he delivers a might punch to Captain America but was blocked by his shield, causing the webhead to grunt in frustration.

At New York, Zero and Axl are attacking the Ultron army, all while X jumps into the air, forming his First Armor and releases a powerful charged shot that eliminates the droids in a single shot. The next scene shows X showcasing the different abilities and transformations after copying the weapon data of Iron Man, Captain America, Hulk, and Thor. The second-to-last scene has Blake standing on a cliff looking to the sky, seeing the images of the rest of her friends that are not a part of this adventure like Ruby, Tails and Scarlet Spider. The final scene is Spider-Man and X giving each other a firm handshake while standing in front of a group shot with the D-Avengers and the Maverick Hunters, all looking ready for a grand adventure.

The ending starts off with all eight Exo Stones spinning in a black void that is slowly filled with the respective colors of each of the D-Avengers as they show up in order. The Chaos Stone appears next to Spider-Man in his classic landing pose, surrounded by his Black Ace, Red Joker, and Aura Arachnid forms. The Espeon Stone shows up with grinning Sonic with his arms crossed, also surrounded by the three different forms he has taken throughout the series: Super Sonic, Hyper Sonic, and Ultra Sonic. The War Stone shows up next to the image of a smiling Ruby hopping in the air, with her Super form as well as her silver "Lunar Maiden" Style Change. The Genesis Stone appears in front of Tails, Weiss, and Pit smiling together. The Dream Stone stands between Blake and Lucina as they hold their respective blades while standing side-by-side. The Nether Stone looks like it's about to be punched by the smirking Knuckles and Yang. The remaining pink and silver Exo Stones appears with Ero and Palutena, with the former in a stoic crossed armed pose while standing behind a smiling Palutena. The last scene is a massive group shot of the D-Avengers smiling, standing in the middle of a circle surrounded by the dozens of friends they've made throughout their adventures, ranging from the Avengers, Mary Jane and Harry Osborn, their friends at Beacon Academy, the Freedom Fighters, the Shepherds, Viridi and Dark Pit, and the Maverick Hunters.
