These are a part of a bigger Marvel Zombies set I've recently completed. The Colonel is a repainted movie Captain America figure (one that came with parachute accessory), with mod to the head and custom sculpted brain. Black Panther was created from quite a few parts; the body from a single card Bullseye with arm removed and sculpting for the bandages on his arm chest and leg. His head is a GI Joe Rise of Cobra Ripcord with cowl sculpted on. Wasp's head is from a GI Joe 5-pack Lady Jaye.
