Excuse me, but... I need some help with a matchup thread, specifically the R.O.B - Dr. Mario matchup.
http://smashboards.com/threads/r-o-b-matchup-analysis-27-dr-mario.407206/
While I've tried to play him for a bit to see how he compares to Mario, (as we've already covered the Mario matchup) he's much, much different compared to the plumber. Slower, tougher, and generally more defensive, I've noticed. For reference, here's the regular Mario matchup thread.

Besides being different, I know that there are at least a few constants between both, that can be said first:
• Both of their N-Airs are decent at getting out of combos, however, since Dr. Mario's does more damage the longer it's out, it could be used to drop down on an enemy, I think? Besides that, R.O.B only has his N-Air to truly space an enemy out, since it swirls around him. With it being slow, either Mario could drop down and N-Air him.
• Capes can reflect R.O.B's projectiles, while fireballs/pills potentially are able to pressure R.O.B as he approaches/you're trying to approach.
• Up-tilt can still be used to juggle, although I think it stops becoming effective 10% earlier.
That being said, I know that there are differences that make this matchup notable compared to the Mario one:
• Both U-Smash and U-Air send your enemy at different angles than Mario's attacks. U-Smash is weird; It sends the enemy diagonally, but... If you hit them with the front of Doc's head, it sends them in the opposite direction, vice versa with the back. Depending on where you are on the stage, you might want different hitboxes to hit your opponent. So, it's a better move than Mario's, but only if you know how to use it, I believe?
U-Air's the same deal, except reversed; If you hit them with the back of Doc's legs, it hits them backward, vice versa with the front. I think this means that you could potentially combo it into Doc's other aerials, instead of keeping them in the air like Mario would. If that's the case, then I'd guess this move is most useful at low percents.
• B-Air and F-Air are much more powerful, and probably more versatile. B-Air just straight up kills near the edge, unlike Mario's, while F-Air can kill R.O.B near 80% if he's in the air.
• D-Air allows Doc to potentially approach an enemy on the ground, or even diagonally, like his N-Air. I think this makes it more versatile than D-Air, especially since Doc already has Mario's D-Air in his Dr. Tornado, but better.
• Dr. Tornado is able to move, albeit a small amount, and can beat out some projectiles.
• Obviously, Dr. Mario is slower, has a smaller jump, and does more damage, which makes him more defensive. Also, without his cape being able to stall him in the air, his recovery is overall worse, although his Down-B helps with going horizontal.
In general, I think Dr. Mario is more defensive than Mario, having a harder time approaching, but his moves are good for knocking people off of you and probably better than killing. While this isn't a gameplay difference, I'd bet that most players choosing him over Mario are more defensive minded, wanting to punish you for your mistakes.
