Wall of text incoming...
I'm just gonna come out and admit it: I really want Dr. Mario back.
I know people are gonna be like, "Oh, he's unnecessary, oh he's just filler material, oh he's a clone and Paper Mario is better". Which, maybe he doesn't really need his own slot, but that doesn't stop me at all from wanting him. And, you know what? I don't think clones are all that bad. Now, don't get it twisted, I'm not promoting laziness or a ****load of clones to get a spot on the roster in any way, but I feel like if done right, clones can be awesome, if you know what I mean. This is exactly how I felt with Doc. He had the same moveset, but I enjoyed playing as him much more than I did with Mario. Unlike Mario, I felt like there was a lot more personality within Doc's character, with his pills and taunts and unlock screen and whatnot. It's hard to explain, but I felt like there was a little more care woven into this "filler character" than even some of the established characters. Also, as we all know, Mario is the de facto "jack of all trades" character in Smash. A lot of times, these types of characters vary little in between games; except for maybe a few tweaks or move changing, their overall playstyle stays the same. So, in my opinion, Doc felt more like a fresh take on an established character than just a "filler character".
With that in mind, if Doc returns, I personally want him to stay the exact same way he was in Melee. Yep, that's right, as a "clony" clone. And I want him as his own character, I don't wanna see some copout solution such as making him an AT, or even worse, making him an alt costume. I see a lot of people suggest this and I just don't feel like it's the right way to bring him back. Not just the obvious facts that I don't want to see him use fireballs instead of pills and that I don't want to see him use the FLUDD instead of the Dr. Tornado, but I'd like him to have his own Target Test again and his own taunts and animations and whatnot. I want to see the "personality" that I talked about earlier brought back and expanded on. I doubt most of these wants that I have would be realized if he turned out to be just an alt, but that's just me.
I see a lot of these characters thrown around in this thread like Bowser Jr and Lip and Starfy, and they just don't interest me much as playable characters. Sure, I figure, with their resume, they're "worthy" of a spot on the roster, but when it comes right down to it, if/when these characters get into Smash, are you going to actually enjoy playing as them? Are you going to actually main these characters and have fun with them? Not saying the characters I listed are bad choices or that they will, in fact, play like ***, but they just don't interest me much as Doc. If I see a DOJO update in the future confirming Starfy as a playable character, it's not gonna shock me or hype me up for Smash 4 as other characters like Mewtwo and K. Rool and Doc would if they were the ones confirmed as playable characters.
So, with all that said, maybe it's just nostalgia and the fact I grew up playing with Doc in Melee is clouding my judgment, and maybe chances are he won't come back as a playable character at least, but I don't really give a ****. I'd like one of my mains back. I'd like Dr. Mario back
