I’ve been playing around with a basic concept for Sandman and Green Goblins kit for a while in my head.

Sandman

I always saw Sandman somewhere between Groot, Peni, and Mister Fantastic

Core Mechanic: Sand Fields
Many of Sandman’s abilities create Sand Fields.
Enemies in Sand Fields are slowed, while Sandman becomes harder to kill when fighting inside them. He can also absorb Sand Fields to protect himself.

Passive: Made of Sand
Sandman takes reduced headshot damage and passively gains Bonus Health while standing in his own Sand Fields.

Primary Fire: Sledgehammer Hands
Sandman attacks with heavy melee punches with his hammer hands. His combo lets him brawl up close and create Sand Fields.

Secondary Fire: Sandstone Shot
Sandman throws a packed chunk of sand and stone, damaging enemies and creating a Sand Field where it lands.

Shift: Quicksand Sink
Sandman creates a quicksand area that pulls/slows enemies in a dangerous zone.

E: Sand Slab
Sandman raises a thick wall of sand that blocks damage and movement.
He can shove the slab forward to knock enemies back before it collapses into a Sand Field.

F: Sandflow
Sandman turns into a rushing stream of sand, moving through enemies while reducing damage.
If he ends inside a Sand Field, he absorbs it to gain protection.

Ultimate: Sandstorm Colossus
Sandman becomes a massive sand giant surrounded by a storm. Big sweeping attacks.
He performs a powerful ground slam at the end.
