Ben Grimm is still Ben Grimm and this Power Man, based upon Mike Deodato's cover does not change his color into a purple man while using his powers. Energy beams would be a nice new progression of the Ultimate Marvel arms race, since for now the Hulk pill is something that isn't suppose to be working, even tho that can be written around so easily. Black Knight, yeah i had totally forgotten him, but that character was a total loser, still why Nick or anyone would want to use that codename again due to the previous' legacy the name carried is beyond me.Seriously, though, the art is great but so far it appears that the ball was once again dropped. 2 of these characters already exist in the UU and the third was strongly suggested to have been Ben Grimm, although it was never truly confirmed. However, we've already seen that the Vision can alter its appearance and gender, so there is a chance that its the same character from the Gah Lak Tus story. Same goes with Black Knight; he could easily have gotten a new costume. How/why all these characters are working together, I guess we'll find out. I just hope they ARE the same characters so that the continuity will at least not be as heavily impacted.
If anything that bothers me the most is Tigra's costume, the boob-belly window (Mike Deodato's cover) is just not efficient whatsoever, this is Ultimate Marvel! Not 616-verse.
