It's trying to erase certain characters or events from history, and Ralph has to stop it.

It could be a future version of Turbo. He has found a way to manipulate time travel and wants to use it to take over all the games. He's bitter about his past defeats and believes that by changing the past and controlling the future, he can become the most powerful character in the arcade. Ralph has to stop him from altering the timelines and ruining all the games.
One interesting plot twist could be that Ralph accidentally travels back in time to the very beginning of his game's creation. He then discovers that the original concept for his character was completely different. Maybe he was supposed to be a hero all along, but a glitch in the programming made him the 'bad guy'. This would force him to re - evaluate his whole identity and purpose in his game world.
It could be a time - traveling villain from the future who wants to change the past to gain more power in their own time. They might try to stop Naruino from achieving their time - travel goals.
A new, time - traveling villain could be introduced. This villain could be from a different dimension where time works differently. He comes to Ninjago to steal its time - related artifacts to power his own dimension. His unfamiliar powers and motives would make him an interesting and unpredictable antagonist.
Perhaps an alien race that has mastered time travel long before humans. They see Earth as a target for conquest, and they use time travel to disrupt history and weaken the planet's defenses. Peggy would have to figure out their plans and find a way to stop them. This would introduce an interesting sci - fi element to the fanfiction, with Peggy having to deal with advanced alien technology and culture.

A jealous character from another game could be the main antagonist. For example, a character who is always in the spotlight in their own game but feels threatened by the Moppet Girl's new - found popularity. They might try to sabotage her and Ralph's adventures.
