Gwen: marvel OC; Avenger.
Her homemade hero outfit. It's made well, and pretty expensive. But her father is rich and likes to spoil her a bit so he helped her get the stuff, as long as she promised not to stop visiting after he and her mom got divorced.
Speed enhancement (feet): these boots,
It's number seven, except with a simpler design on the shoe part. The arch thing allows the wearer to jump at least ten feet in the air, and when they run, it pushes them farther, allowing them to go faster. The bottom of the arch is a heavish metal ball shape so that when you kick someone, it still hurts just as much as as a normal foot would
The shoes shown above also blend in with this outfit which is actually protected from bullets. (It has a bullet proof vest.)
This is the helmet she wears, except without the designs and it's the same color as the rest of the outfit. There is a glass pane over the eyes that can be removed if it's raining. The glass is bullet proof. The helmet itself is also bullet proof. It also has a night vision option but can only be used when the glass is up.
The buckler
The buckler can fold in on itself so that it makes a slightly bulky ball that she wears at her hip until she grabs the handle and squeezes which then opens it.
The sword
The sword is a copy of Sif's. Made of vibranium, because Gwen's father is rich and likes to spoil her. Though he only got her enough vibranium to make her sword and buckler.
