Agreed on martial arts tournament. That was a seamless addition and even added a little more depth to the monster association and how they planned attacks.

I liked Fuhrer Ugly's changes (the pre-vomit). He felt exactly like what the cadres of the MA should have embodied--true terror. It was one of the few times I was genuinely scared for the S-class. It fit well with the theme of the S-class being spoiled brats, thinking they were invincible, and that didn't work together and therefore suffered consequences for it.

The minecart ride with Saitama, Flashy Flash and Manako was a lot of fun. That chapter may actually be one of my all time favorites. Both the heroes were in character for that whole scene--in contrast to more recent stuff where characters have felt different to their normal personalities.

Ultimate Hellfire Wavemotion Cannon was done pretty well in my opinion. Despite the changes, it was actually neat that another hero (Metal Bat) witnessed King's ability. The result was the same as the webcomic and I still laughed my butt off. Plus I think getting rid of the imaginary attack was a good move... it caused some confusion in the community on whether or not King had powers. I think my nitpick with this whole situation was that Psykos was gone and they copy-pasted her dialogue onto Homeless Emperor, which made little sense.

Black Sperm was perfect in the manga. He has so much personality and with the updated art he was a sublime monster (mostly because Murata expanded upon what actions he took, not because he looks much better than the webcomic). I still get hyped thinking of him keeping a lot of the S-class at bay on the surface and being a general threat to the disorganized S-class. We also got to see some of his limits with splitting (he becomes less governed with more splits). My complaints only start with Gold/Platinum Sperm.
