Comment on what world visits the ME universe (basically who comes to visit the Shepard family )

Home: the apartment from the Citadel DLC but with  revamped rooms

His kids
Mark Grayson(Invincible)[crossover with the show and a bit of the comics]
He's the oldest of the kids, his mother blamed him for his dad's attack(like she did in the comics) he's destroyed part of Amber's house(just her room)

Conner (Young Justice)-he heard Superman say that Conner needs to be dealt with as Kara should take his place and he met Tala, who he didn't rat out to the league and in return, she could send him to a new home

Saki-(that manga that I don't wanna name for reasons) - it was before any of the bad stuff happened to her and she wished for a better parent

Butters-(South Park) - he's been through enough and he deserves a better family (plus imagine his conversation with Tali, or Charlie ((if I had her )

I wanted to add Charlie and Emily from Hazbin Hotel but I might have to change a few things, would this be okay?

Also, I might add more

Some plot points

Conner fights a threeser maw, he loves it, and Shepard says
"Ah, see look how happy I've made him

Mark lifts a huge container over Ashley's house but Shepard tells him not to drop it on the house

Shepard brutalized the turian Councilor after he tried to have his kids experimented on (like Mikey Mouse did to the Jonas brother in that episode of South Park)

Butters's personality wins Aria over as she finds him adorable

In the Mk world, Conner is named an honorary Shokan by Goro

Mark and Shepard brutalized Nolan( Shepard's guns might be enough to damage him )

Also you can suggest your ideas too

As for the pairings
Shepard x comment whoever you think should be or how many

Conner x Starfire( her appearance is the DCA films)

Mark x Kate (yeah I'm changing the script but I might go with Eve)
