ReBoot - My Two Bobs

Bob and Dot get engaged as a portal opens from the web, bringing through Ray Tracer and a second Bob. The two Bobs look alike, sparking confusion about who is the original. Dot and the Mainframers begin to debate and label them, setting up the central identity crisis.

Dot, Matrix, and the Guardians scramble to determine which Bob is real and which is the copy. The two Bobs' likenesses complicate conversations and plans for the future. The distinction becomes the film's running puzzle.

Bob's reboot ability lets him quickly adapt, and he bonds with Matrix and the other Mainframers by helping them win games. His reliability contrasts with Glitch Bob's unpredictable nature, forcing the team to lean on him. This solidifies Bob's place in the group despite the clone confusion.

Counseling from Phong and Mouse leads Dot to decide to marry the new Bob, intensifying the love triangle under the looming wedding. Glitch Bob makes one last, clumsy attempt to restore his original form to win Dot back. The tension sets the stage for the wedding day.

Glitch Bob's earnest attempt to return to his original form ends in catastrophe as he is left in a catatonic state, covered in a starry crystal that resists penetration. Dot keeps planning the wedding despite the setback. The situation elevates the stakes for everyone involved.

On the wedding day, Welman becomes intelligible enough to escort Dot down the aisle, wearing a mechanical suit thanks to the infection transfer from Enzo's icon. It is a poignant moment that shows how the infection changes even the family of Mainframe. The wedding proceeds amid the crisis.

Glitch's deteriorating condition on the wedding day prompts the Guardians to plan a separation of Glitch from Bob and a revival, returning to the Supercomputer to work on him. The crisis disrupts the ceremony and draws keytools back to the Supercomputer. The tension peaks as they race to stabilize Glitch.

The Guardians uncover that Web Bob's code no longer matches their files, suggesting he is the copy. Web Bob returns to Mainframe to try to stop the wedding, but Dot rejects him in favor of the new Bob. Glitch secretly lends a helping hand by providing some code to Web Bob, reviving him to his original form.

The loss of the code causes the Bob Dot was marrying to shapeshift, revealing Web Bob is the original and the new Bob is Megabyte in disguise. Bob confronts Megabyte in the church, but Megabyte escapes by disguising himself as a Binome. The revelation shatters the wedding's assumptions.

An investigation reveals Megabyte has become a Trojan Horse virus, granting him the power to shapeshift and impersonate anyone. He had previously stolen part of Bob's Guardian code when he crushed Glitch at the end of Season 2 and used that code to impersonate until Glitch returned it. The virus marks a new threat to Mainframe.

Megabyte disguises himself as Mike the TV and other Mainframers, assembling a viral army. He eludes capture through a web of aliases and a doppelgänger before infiltrating the war room by taking on the form of Frisket. The conspiracy spreads quickly through the grid.

Megabyte suborns Dot's father and captures Enzo, gaining control of the Principal Office. The infiltration marks a turning point as the virus asserts its dominance over Mainframe's vital routines. The threat becomes personal for Dot and the other Mainframers.

The film ends with Megabyte proclaiming his predatory virus nature and declaring revenge on the Mainframers; his final line signals a menacing new phase for the series. The threat is clear as the credits roll, ending with an ominous vow of pursuit. Prepare yourselves for the hunt is the chilling echo of his threat.
