Stonewall

History

 Before the  Skrulls'  Secret Invasion,  Nick Fury asked  Daisy Johnson to recruit people from his files.  They were to become his new secret strike force.  One of those Johnson recruited was a man named Jerry Sledge.  He was later referred to as Stonewall, due to the stone-like appearance his skin took on when he increased in size.  After being seriously beaten by Fury in a training match, Stonewall understood Fury's strategies and how serious was the Skrull threat to Earth and devoted himself to Fury's  Secret Warriors.   
 

Secret Warrior

As a loyal member to Nick Fury's team, Stonewall fought  Hydra alongside team members  Yo Yo Rodriguez, Daisy Johnson, Hellfire, and  The Druid.   When Daisy decided to let the Secret Warriors engage The  Gorgon (a member of Hydra who was believed to be dead) Yo Yo Rodriguez was severely injured.  Stonewall stayed alongside her in order, to make sure she was safe.   

Parentage 

When the Secret Warriors faced members of Norman Osborn's Dark Avengers, Stonewall came into face-to-face combat with Ares.  During the battle, he was hit by Ares' axe and took on a metallic appearance instead of stone.  This has led to much speculation that his powers are hereditary, which he might have inherited from the Absorbing Man. 
  

The Truth

 It was revealed in issue #12 of Secret Warriors, that Stonewall's father is in fact Absorbing Man, who he visited with Yo-Yo in prison.
 
Nick Fury, Stonewall and the rest of the Secret Warriors recently find Steve Rogers and members of the New Avengers. Together they repel incoming HAMMER agents and return to the Avengers safehouse in Brooklyn. They just learned about the assault on Thor by the Initiative and prepare to strike back.  

Powers

 

Strength 

As the name Stonewall suggests, he has extreme strength & endurance beyond that of a normal human being.  He is able to withstand heavy attacks, absorb the energy and redirect it. 
  

Superhuman Growth 

Stonewall has been able to substantially increase his size & mass.  When he grows in size, his skin does not stretch, and his mass increases in ratio.

Material Absorption & Metamorphosis

When attacked by Gorgon, Stonewall didn't just grow in size but also changed his physiology.  He appeared to be made of stone.  In a fight against Ares, Stonewall was attacked by Ares' axe.  He seemed to reproduce the metallic substance of the axe and changed his own genetic structure into the same material.
 
 

Miscellaneous 

  
Stonewall is the second Marvel character to have this codename.  Therefore he is not to be confused with Louis Hamilton, the original Stonewall who was a member of Mystique's Freedom Force & Brotherhood of Evil Mutants.
