Haven't played Pulse Man, but I recall not liking Drill Dozer, I don't remember why so I'd have to replay it to see how it is again.
Anyhow, I've noticed Mewtwo's design has changed throughout time, a design change I really don't care for. I still like Mewtwo regardless, but I feel a lot of Mewtwo's charm has diminished due to making him less serious looking and more skinny. Instead of taking pictures from Sugimori, the movies and other things, I went ahead and cranked up Dolphin emulator to the max settings.
Here below you'll see Pokemon XD: Gale of Darkness (Gamecube) right next to Pokemon Battle Revolution (Wii) which is how Mewtwo is portrayed now. Clearly you'll see Battle Revolution has far superior graphics, however I'm not here to discuss that as the former is using an upgraded Stadium model. I'm merely talking about the art style used, Mewtwo just...his face got pretty weird to say the least.
Thankfully, thanks to Melee, Mewtwo has a much better model in the classic style which I can actually show.
My main point is although Mewtwo is pretty much my favorite Pokemon along with Rayquaza, them removing features and altering it loses a lot of what made me like the design in the first place. It feels very inferior, and more stereotypical modernization design that wasn't needed.
