For Avenger OCs

They baby Avengers had slowly started to be around the compound less and less. To the point where one member of the team might get a glimpse of a white glove or a muddy footprint on the ceiling. Tony had been one of the only ones to see them, yelling at them and reprimanded them for deliberately disobeying him again. That's when they just stopped showing up entirely, Rachael's room seemed extra quiet at night as well. No one thought anything of it until a week so later when an almost hysterical May Parker showed up at the compound looking for her nephew.

For Villains

The youngest Avengers were out in the open by themselves and undefended after Tony Stark took their suits back and given them news that neither of them had wanted. Seems like the perfect opportunity to nab them and use it against the avengers or get back at them for what they did to you.
