All of Doom’s combos are pretty modular. I’d say start off with the Buktooth and duckstrong loops. The notations for both combos are splattered all over these pages.
If you want something “tougher” with more optimized damage, you should try sehmehnov’s combo midscreen, and then the maziodyne corner combo as they both milk out a little more damage.
Where exactly, the references I’m seeing are all from vanilla not from UMvC3, has anything changed?
The maziodyne and sehmehnov ones are on this page and the page before. They are a little difficult I would say especially if you have no doom experience. But it might jsut be bettter to learn those straight up since they are the most optimized ones.
anyway buktooth one is the same as vanilla and duckstrong is the corner one, also same as vanilla. timing may have changed in the buktooth one slightly, but they are fairly easy to learn and do some nice damage.
just search for buktooth and duckstrong in the search box.
I have a pretty scrub question but how do you land Doom fast enough after hes BnB ( M,M, F.H, S) so you can dash, otg and do it all over again.
I’ve heard people are using M to somehow land faster but I have no idea how that works exactely. Can you tell me the exact input and timing for the faster landing after the S. Thanks. 
after you input the S in the air string, immediately air dash down forward and press H. IF you ever air dash with doom you notice that he floats to the ground at the end of the dash. by pressing an attack button, you negate this floating property and cause doom just to fall quickly to the ground. Once you land, I do, dash forward jump cancel, air dash down forward, then OTG H.
I’m sure you could probably do: land, jump air dash down forward, OTG M or H.
i hate dooms ray gun 
im trying to lean some of dooms bnbs nd i get the ray gun instead of foot dive 
How do you connect Air :s: after Air :f::h: outside of the corner? It only seems to connect sometimes for me.
Launch, then do j.M as early as possible, do j.M again, then j.f+H and j.S.
hello, im new to doom and all i know to do right now is the buk combo but ive been seeing the midscreen ccombo where you have to tri dash to get the otg to keep the combo going…anybody know the notations or tell me how to do it?
2L 2H 5S {j.L j.6H ADDF land 2M 5S} x2, Buktooth to j.M j.M j.6H j.S ADDF land 5H 5S j.M j.M j.6H j.S does ~870k with 1 bar. It’s the old midscreen combo but with two maziodyne loops thrown in. Only tested on a few medium-sized characters.
Yay, Doom.
Hello gentlemen and scholars.
I need some help, if you’d be so kind. I’m rather new to the game, and I’m trying to learn how to play Doom.
I’ve lurked this thread and honestly can’t make heads or tails of most of the stuff being mentioned.
What I think I know: when you launch an opponent you extend the air combo with his 8-way air dash into more hits before launching them to the ground, then use standing H to OTG then launch and repeat.
The thing I’m having trouble with is the air dash piece of the combo. When I air dash my opponent will fall out. I’ve tried air dashing different ways to avoid it but I still have trouble.
I guess the point of this whole post would be to ask if anyone could give me a beginner friendly explanation of how to do these combos successfully, if you would be so kind
Is their a way to combo his assist (missle) to a combo with wolverine?
Ummm…I’m not sure exactly what you’re looking for, but a combo that I made up in my head that should work is:
LMHS, sj. MMH xx drill claw, dive kick, land, H, S+Missiles, sj. MMHS, land, Missiles hit, fatal claw
Ah, hey, you’re from Edmonton, right?
From what it sounds like, you’re mashing up 2 different combos. You want to use the air dash combo extensions for the buktooth loop (which does not need OTGs). You use tri-dash (which is just air dash down forward very close to the ground) to get the OTG standing H after what most people call the clockwork/shady k loop (which is LMHS, sj. MMHS)
I think you’ve already started off trying to learn the buktooth loop. It’ll probably help to just look for tutorials of it. I think this one was done by one of the users on SRK.

Yeah I am. I’ve been a little bit out of the FG loop for a while. Been busy with other stuff. That video helped me understand things a lot better, thanks a bunch.
To the training room!
Another question: near the end of the end of the loop when he does footdive > footdive, he gets to the ground really fast to OTG into his hyper
Is there a specific way to do that? I tried air dashing after the footdive S but it doesn’t seem to work.
When I finish the S I just float down and barely have time to OTG into my hyper
I think I pretty much go over it in the video. After you connecgt with the S, you do an airdash. It will cause u to float towards the ground. During the float, you need to use a normal so that Doom cancels the float animation and falls to the floor. any attack will work, but its recommended that you use H, (the faster normals might cause unwanted hits in x factor).
The H will come out, and doom will fall while the gun whiffs. Its in the video.
Ah okay. I must’ve missed that in the video. Thanks.
hi guys!
I’m starting to learn doom but I don’t know whats a good BnB combo to start off with (corner and midscreen). I was learning [media=youtube]12kCkw854cw[/media] but then I realized it was MvC3, not UMvC3
Thanks for making this 
I put Doom on my team I need still need to learn how to use him properly
