This might have already been addressed, but after looking at the Pyrosphere stage, the direct, and Sakurai's posts I observed some things.
- Ridley WILL be in the game 100%, either as a boss or a playable character.
- The way he moves on Pyrosphere in the direct seemed awkward for several reasons
1. If he was as big as Ridley is (Sakurai is keeping this game detailed, and Boss ridley wouldn't be scaled down for any reasons that I see) then it would appear he would clip through the platforms on Pyrosphere, which wouldn't look visually appearing.
2. If he's a "smaller" version of a stage hazard, why? Why size down a non-playable boss character?
3. We've observed from several PotD's that Sakurai is paying very very very close attention to detail in this game. A YouTuber by the name of cephalopod17 noticed something about the boss fight seen here. In his Video, "Possible Metroid Newcomers for SSB4 - The Ridley Video" at 12:20 in the video, he makes a good point: in almost every Metroid game, except the original, Ridley's boss fights are extremely hectic. The direct showed us a slow moving object that didn't even acknowledge Pikachu. If Sakurai was really putting as much detail into SSB4 as we've seen, Ridley should be swooping around, clawing, fireball-ing, etc. You could argue this is to keep the game less hectic so you don't lose track, but stages in the past(Summit, Mario Circuit, Rumble Falls(Worst stage ever), etc.) have shown semi fast to fast stage hazards. This a good reason (in my opinion) why I really don't think he's just a boss.
4. We've only ever "seen" Ridley once. We've never seen him in any other screenshots, leaked footage, etc.
- The Size argument is complete bull**** in this game, and you all know it. Even Sakurai himself has said "Size doesn't matter." Yes, yes, I know what you're thinking. SOME THINGS ARE JUST TOO BIG TO EVEN BE IN THIS GAME. We can look at great examples of re-sizing in the past games, even inconsistencies.
1. The Chars. You've all heard about Kirby, Olimar, and Pikachu I'm sure. Instead of listing one's that aren't canon sizes in smash bros, let's list 1 char that is perfectly canon size in Smash...! No one. There's not a single char in this game who is the exact millimeter that they are in their canon (which, by the way, also is inconsistent.)
2. The Stages. Wozny, what do you mean? Luigi's mansion and Mario Circuit (assuming all chars in the Mario kart series fit in a kart, which Bowser would never on MC) were both sized down. So was Fountain of Dreams, the Arwings on all Starfox stages, And Mute Cuty. Things that have been sized up? Distant Planet, and the Bulbord.
- Character Deconfirmation. 90% of people, including myself, thought Toon Link was out when Spirit Tracks was revealed.... wait? He's playable! let's think about Deconfirmation in Smash, beginning with Melee. On the stage Corneria, when using Fox or Falco (even if both were there at once) taunting would cause the Starfox crew to contact the player. As Fox, Falco would be on the comm, and vice versa for Falco. So, what gives? Fox is there.. and here....? Obviously, he can't be playable. Next, on every Smash Bros. F-Zero stage, Falcon races in the background. Again, breaking the canon. DK appears on 75m, so why is he playable? Squirtle was literally part of a stage in SSBM (Pokefloats), then he became playable. So, back to the point, considering how we haven't even seen Riddles yet and people are deconfirming him is ridiculous. It's funny, because these are mostly the same people that thing a new FE stage means Chrom confirmed 111100000%.
- Lil Mac was shorter as an Assist Trophy than he is as a playable.
- Charizard, Ridley, and Dedede have been physically present in every SSB game. Charizard as a pokeball and char. Ridley seen flying in the BG of Planet Zebes on N64, in the intro of SSBM, and a boss in SSBB. Dedede as a BG effect for Dream World in both SSB64 and SSBM, and playable in SSBB.
- Sakurai. Yes, Sakurai. In the past few months, he has surely made the SB community happy(GC controller, FD mode on all stages, etc.) This man is fully aware that the Space Dragon is requested, how the hell would he miss it? In my opinion, he cares a lot about his fans, contrary to what people say, and he acknowledges the west's request for a fighter who fits the qualities of:
1. Iconic.
2. Important to their franchise.
3. Great Moveset Potential.
4. Popular.
To end it, Villager was once seen as an impossiblity because Sakurai himself stated AC characters are impossible because of their cuteness (I thought it was ironic with Pika, Yoshi and Kirby in the game). However, with his psychotic look, Villager is in SSB4.
Nobody should read this random post, say "This 17 year old kid posted that Ridley is in SSB4 as a fighter" , and get mad if he isn't. I'm being unbiased with the facts here. In my personal belief, yes. Ridley will be a Newcomer in SSB4.
