Who could be the main villain in a Gremlins 2: The New Batch fanfiction story?

One possible plot could be that a new type of gremlin is accidentally created in a lab near the Clamp Center. This new gremlin has the ability to fly and is much smarter than the regular ones. The main character, Billy, has to team up with Gizmo again to find a way to stop this new threat before it takes over the city.

It could be a speedster from another universe who has come to challenge Flash. This villain might have some unique powers related to speed that Flash has never encountered before, like the ability to steal speed from other objects or people.

In a new Ash Unova fanfiction, the main villain could be a scientist who is conducting unethical experiments on Unova Pokémon. He believes that by fusing different Pokémon together, he can create the ultimate Pokémon. His experiments are causing harm to the Pokémon involved and are also disrupting the natural balance in the Unova region. Ash discovers what's going on and has to stop the scientist, not only to protect the Pokémon but also to save the Unova region from the potential disasters that could be caused by these abnormal Pokémon creations.

A jealous show - dog breeder could be the new villain. He sees the Dalmatians getting all the attention and decides to plot against them. He tries to frame them for causing chaos at dog shows so that his own dogs can win all the prizes.

A possible main villain could be an ancient sorcerer from the new dimension who has been awakened from a long slumber. He's enraged that the wizarding world has been interfering with his dimension's magic, and decides to take revenge on Harry Potter's world. He has powers that are unknown to the normal wizarding world, like the ability to control time in his dimension, which makes him a formidable foe.

A corrupt politician could be the new villain. He uses his power and influence to cover up his illegal activities, like embezzling funds meant for the city's development. The Punisher would see through his lies and decide to take him down.

It could be a long - lost relative of Voldemort, carrying on his dark legacy.

A tech - genius who was once a protégé of Tony Stark but turned against him out of jealousy. He creates his own army of robotic suits.

I don't know for sure since I don't have the details of this 'gremlins first story'. It could be a human protagonist who discovers the gremlins.

A tech - savvy billionaire could be the new villain. He uses his wealth and technology to create chaos, like hacking into government systems and causing global financial meltdowns. He believes that the world needs to be 'reset' under his control, and Ethan Hunt has to stop him before it's too late.
