20) “Dark of the Moon”
After Yuri Watanabe's former mentor Augustus Roman announces that a new Supervillain prison called the Cellar II is being held in the Moon, Spider-Man and his team go there to inspect the new facility. Unfortunately, they discover that Roman is in reality forging protocols to duplicate the super-villain inmates' powers and channel them into a new armor he built to bring crime to his knees as the Regent, but by the most extreme matters. Spider-Man and the team now work to put a stop on the Regent's plans and expose him for his true colors. But first, they must get past the prison's inmates (consisting of the remaining members of the Sinister Six and the Dragon's Breath) who happen to be under the Regent's control.

21) “Negative Endgame”
After overhearing that Mister Negative has defeated the Mandarin and obtained his Ten Rings to resurrect the forbidden army of Attila the Hun with the goal to overthrow all nations and renew them to his own liking, Spider-Man and Shang-Chi must lead their superhero allies on a last-ditch effort to defeat Mister Negative and save China and the world. Doctor Octopus also seeks to challenge Mister Negative over the Ten Rings for his own purposes, even though one of the rings repeatedly forces him to experience memories of the old misery of his life, including ones with his own abusive father Torbert and a jock and bully named Steve.

22) “A Champion's Christmas”
After the final defeats of Martin Li and Doctor Octopus and the end of the Dragon's Breath, Peter and his friends prepare to enjoy a comfortable party in Christmas Eve. Peter enjoys himself by telling the Mutant and Inhuman children four stories about his friends' adventures during Christmas, which are surprisingly coming true as he tells. Like City of Heroes in Season 1 and Tales of Heroes, this episode features an anthology format, being split in four different segments:
 * “White Rabbit Hunt”: Tigra and White Wolf chase after White Rabbit, a new criminal vigilante planning to commit as much mischief as possible to ruin the citizens' Christmas night.
 * “Ant-Ballerinas”: Cassie Lang has to participate her school's Christmas ballet, but when her ballet set is accidentally shrunk by a Pym Particle device and lost in the middle of the Christmas gifts, she (as Ant-Girl) and Gwen (as Ghost Spider) shrink themselves to the size of an ant and venture themselves in a long way to retrieve the shrunk set, even though they are relentlessly chased by their neighbor's cat, who is mistaking them as mice and eager to devour them.
 * “Frost Fight”: Frost Giant Ymir invades New York to search for the Casket of Ancient Winters recently guarded on the main museum. But Kid Arachnid, Spider-Girl, Reptil and Ms. Marvel, who have more than a few surprises up their sleeves, will get the Frost Giant to fall into numerous pranks and embarrassing bobby traps until he finally relents from his plans.
 * “Jingle Bell Rock”: Firestar and Wave agree to take part in Luna Snow's pop-rock show to bring more joy to New York in Christmas. Screwball and Typhoid Mary plan to sabotage their show by any means, but the three girls' performance will soon lead the two villainesses into embarrassing mishaps.

23) “Into the Spider-Verse, Part 1”
Looking for revenge for his previous defeat on the Champions' hands, the Regent escapes prison and allies himself with demonic sorcerer Morlun, who leads him to a quest across dimensions of the Multiverse to find the resources they need. Alerted of their plans by Master of the Mystic Arts Madame Web, Spider-Man, Kid Arachnid, Ghost-Spider and Spider-Girl also follow the two villains to stop their plans. Their first dimensional stops are in the futuristic world of Marvel 2099, where they team up with Spider-Man 2099 on defeating Maestro, and then in the Marvel Noir universe where they help Spider-Man Noir apprehend Scorpion and his mob.

24) “Into the Spider-Verse, Part 2”
While chasing Morlun and Regent across the Multiverse, Spider-Man and his team arrive back in the Revengers' reality, where they help Spider-Punk and the Revengers defeat the Symbiote-mutated Sinister Filth. Then, the team heads to a Caribbean-themed reality, where they help Captain Spider (a pirate version of Spider-Man) and his crew defeat the Sinister Dutchman's crew led by Captain Octopus (an older and mutated pirate version of Doctor Octopus).

25) “Into the Spider-Verse, Part 3”
As Spider-Man and his team continue chasing Morlun and Regent across the Multiverse, they land in the Secret Warriors' reality, where they help the Secret Warriors (now joined by Wakandan Princess Shuri) contend with Madame Hydra, who had obtained Kree technology for her purposes against the Americans. Then, their last stop before heading back home is in Earth-199999, where they help that reality's version of Peter Parker overcome grief of Tony Stark's death and the disassembling of the Avengers and expose Quentin Beck / Mysterio, who is faking his heroic acts using illusion drones which summon the Elementals.

26) “Into the Spider-Verse, Part 4”
After Spider-Man and his team finally end up back in their own universe, they find out that the Regent has double-crossed Morlun and used his recreated armor to replicate the powers of the villains from all the universes to become the Ultimate Regent, while also creating an army of androids to bring New York to its knees. With Madame Web's help, Spider-Man and his team summon their fellow Champions and all the Spider-people from the alternate dimensions to battle the Regent's army and save New York from ultimate doom.

Season 3
Three months after the Regent's final defeat, Peter Parker and his friends continue their roles as heroes while attending to their last year in high school before graduation. Along the way, they also need to contend with new potential foes and threats, such as Riot and his Symbiote force, who took over the Kree planet of Hala intending to conquer the galaxy on a way the Kree failed to do, and Raymond Warren's son Gabriel, who is resuming his father's work with human cloning and has become the new Jackal. Spider-Man and his team also need to contend with the threats of the Arachnid Queen, a vicious force of Norman Osborn's past making and the First Spider who seeks to bring humans to their knees and convert them into a new, and "superior" species.
