Avengers Forever is a personal favorite. And, there are many, many memorable panels. But, I always gravitate to this one. I never loved the Yellowjacket character before this series. But, after … well … I can’t wait for Hank Pym to split his personality and start kicking ass with verve and arrogance again. YJ … you had me at kicking two dudes in the face at one time. Wasp/Scientist Supreme is nice. Sawyer as superhero is better.
How about John Walker ditches the USAgent persona and puts on the yellow and black duds? Hey, Marvel … make it happen! Um … please?
Marvel Smart Ass 
I just read a Busiek era Avengers Annual where the Yellowjacket personality splits off and then grows a new body from the dimension where Giant-Man gets his extra mass. Hank Pym might be due for another mental breakdown. He is already dressing as his dead ex-wife and giving flesh grafts to the robot who has her brain patterns.
Also Avengers Forever is great.
