Really minor upgrades, more "plastic" surgery then anything else. I know, couldn't help it. Do you remember the 20th anniversary Hulk and those lips. the 1st promo picture was pretty polarizing, some called it pickle lips or Mic Jagger. When it arrived in hand, it wasn't so bad in person. However it's still hard to unsee it on the shelf. I ended up sanding them down and exposing more of the teeth. Then finished what Hasbro should of done with shading the face and the back trim on the ripped pants. My custom avengers now have a Hulk. It's not much, but let me know what you think.
