Liz will returned and become New Vulture after Far From Home
Liz Toomes (or Allen in comics) one of peter parker love interest in comics,animations and 2017 film Spidermam:Homecoming. After her father Adrian Toomes (Vulture) was arrested and imprisoned for possible life until death that cause his family move and watch Adrian on trial for mostly crimes for stealing stark techs and selling legally alien weapons,so this where where Vulture and Liz story end but not case,in like marvel universe one time characters whole make come back appearances returned like Red Skull for 8 years since back Captain American:First Avengers 2011 he return 7 years in infinity war as as guardian of soul stone. MCU characters whole killed off and just one time again come back for Liz Toomes marvel don't have plans for her she was just peter parker one time love interest,but what likely if how she do
Vulture (Adrian Toomes) who only person have knowledge only peter parker true identity as spiderman that plot hole in MCU,who Vulture going tell someone this information like maybe like his daughter Liz. If Adrian tell Liz about peter parker in fact as spiderman she realized it all make is sense now like how Peter actually at prom and how peter know spiderman became they same person. Now Liz what she do with this revelation information will maybe Liz report about spiderman identity revealed to public,watch every he care about like his friend's & family be target by criminals & super villains peter have putting away and defeated or maybe Liz go route 2007 Spiderman 3 with Harry dawn new green goblin seek vengeance against spiderman (Peter Parker) for killing father. Think Liz would do same choice kill Peter on own personal hands with help of Tinkerer only crew member was arrested created new Vulture to kill Peter Parker for destroyed her family
Fulling aware who is Liz Allen in comics but what if alternative version of Liz like what if in marvel comics,in homecoming film was is what if for character Liz Allen. What of Liz was daughter of Vulture in homecoming when Liz say this line to Peter trip to Washington D.C "This is Really Important. This is my future."this was reference how Liz future going perfect how his going artist,get a perfect boy,loving parents and going ivy league university in new girl. But now all that is ruin by Peter Parker cause he going doing what is right,if he having stop Vulture (Adrian Toomes) Liz and her mother wouldn't move to new state and cost destroyed her family now it was foreshadowing? This was not first time superhero movie created a innocent civilian turn into a villain,best example are Ozymandias,Harvey Dent,Helmut Zemo,Norman Osborn,Magneto,Zod and Chris D'Amico once was victims hero action or quote from comic author Alan Moore (wrote
Batman: The Killing Joke,Watchmen and From Hell) say
“All it takes is one bad day to reduce the sanest man alive to lunacy. That's how far the world is from where I am. Just one bad day.”
I would predicate like ending of far from home or opening like third sequel in MCU:Spiderman series scene Liz talking with her family,his told her ex boyfriend Peter Parker is spiderman it all make sense to Liz. Like in third film Liz became New Vulture be secondary villain to seek to destroy Peter Parker life by taking away people care like her father say to people when he treatment he in homecoming "You forget any of this happened. And don't you ever, ever, interfere with my business again. 'Cause if you do, I will kill you and everybody you love. I will kill you dead! That what I'll do to protect my family, Pete. You understand?" look like Liz fill her promise to kill everybody peter have love and kill him
