Petition to make Evelyn from Everything Everywhere All At Once to travel to the MCU and give The Council of Kangs the Big Smackdown actually.
Like just imagine it, a harmless-looking Chinese old lady suddenly appears in New York and whatever monitoring systems the world organisations have set up for detecting people with superpowers register her as an anomaly. But it can't quite tell what sort of anomaly she is, because at this point in the MCU world 616, they're used to time travel but haven't quite discovered the TVA and multiversal beings yet.
So they bring her in for questioning. She says she runs a coin operated laundromat, she talks about her husband, daughter and daughter's girlfriend, her estranged and recently reconnected father, etc. She moves like a civilian, acts and emotes like a civilian, has the build of a civilian and senses/reflexes of a civilian. Her confusion and fear seems genuine, she keeps wringing her hands nonstop being anxious about getting back to her family, and her self-soothing response to that is apparently cleaning, cutting fruit for the people stationed to monitor her, and making craft items with googly eyes on them. And breathing exercises. Because her doctor recommended them.
Dr Strange is not available for being called in to look at her yet, so she's still being held somewhere for further confirmation on his par, but as time goes on, everyone more or less ends up believing this is legit just a poor little old lady, at the wrong place at the wrong time. Maybe the machine that keeps tagging her as an anomaly is only reading the energy signature of her universe off of her? So they're all feeling kinda bad for her, reassuring her they'll help her get back soon.
Meanwhile Evelyn's genuinely freaking out about how to get back to Waymond and Joy, or at least tell them where she's gone so Waymond doesn't worry out of his mind and her daughter's abandonment issues don't get triggered hard again. They've come so far! They're even doing family therapy! They have family dinners regularly involving Becky, and it's not often bad or weird when her father's also there now! Joy's happier than she's seen in years!
She is NOT about to let this sudden random setback undo all the progress her little family has made.
And if somewhere along the way, she discovers she can still tap into all the powers of every Evelyn in her original universe cluster, and uses that to curbstomp the Kang sent to capture her (because their tech also registered the weird multiversal wrinkle that sent her here, so they are determined to question her or use her, see if there are even MORE multiverses out there with Kangs to control them) AND psychically banish the entire council through him (because her ability is different from theirs, she's literally able to access her other selves through her own body and no Kang has ever faced her before, so they don't know this), well. She's had scarier adventures than this trying to save her own daughter and her own multiverse.
Also, Bob Reynolds gets an awkward auntie mothering session from her some time before the big showdown happens. Evelyn can sense that his Bob/Sentry/Void situation is not dissimilar to Joy/Jobu, so advice is given, heart to hearts are had over comfort fruit platters, and Bob gets a ginormously stilted hug, hand pats and "I'm sure your mom would be proud of you" from her (she's been practicing showing affection more openly with Joy and Becky, and getting better at it!), that is simultaneously very ugly-cry inducing and healing for the poor guy.
(Something probably gets done about Loki in the Citadel too.)
