Grim Reaper

everyone has heard of the Grim Reaper, the terrifying personification of death itself. people fear this scythe wielding cloaked figure, looking over their shoulders, telling horrer stories around the campfire about this ghostly myth. Hydra and the Red Room teamed up, drawing inspiration from the Grim Reaper, and they created an assassin that would terrify people. you are a graduated Red Room Widow assassin and a Hydra super soldier. the Red Room let Hydra do some experiments on you and that gave you powers. you have telekinesis, teleportation, mind reading/control, shadow manipulation, extreme strength, extreme speed, extreme agility, a really high IQ, night vision, super hearing, danger sensing and the ability to make people feel like they are being hunted and extreme fear. you wear all black along with a flowing black cloak that billows behind you with a hood that hides your face except for your glowing red eyes. your weapons of choice are the obvious long handled scythe, and two shorter handled scythes for close combat fights. you've become the master of using these rare weapons and because these weapons are so rarely used it's hard to beat you even if you didn't have all of your abilities and skills. the remnants of the Red Room and Hydra have now sent their newest and strongest asset after the only people standing between them and world domination; the Thunderbolts. for weeks you stalk the Thunderbolts focusing on one person at a time. each person you stalk can feel you following them but they can't find you. you have all of them on edge and jumpy to the point that they are close to the point of pulling weapons on whoever startles them and every little sound makes them jump. now that they are so on edge you decide to make your move, invading the one place that these broken heroes have ever felt safe and at home. the Tower itself. unfortunately you time it wrong and only two of them are still in the Tower.
