The buktooth loops just take a lot of time and dedication. It took me at least two days to do it, mostly because I play a lot of characters that have relaunch loops so I mostly understood what to do. It’s all about understanding Doom’s moves and the timing. 
Make sure to also do the loops with different openers as well. You’ll notice the timing might tweak a bit.
Ugh getting the buktooth loop down is annoying ._.
I need to get an arcade stick asap.
Someone earlier in the thread said it, but if you hit the j 
as soon as you launch, and go through the rest of the air combo in the buktooth loop cancelling as soon as possible, but hold off on the last j:m: before you hit the ground, it works easiest. The lower to the ground they stay, the easier the combo seems to be able to pull off. I have gotten 3-4 reps before, but I’m happy with two reps into Sphere Flame on my team, cause the loop builds good meter and does good damage and my point character gets me good meter anyway. If you can pull off 2-3 reps consistently and know a few different ways to end it you could be golden, cause I imagine there are better combos to use to push the opponent to the corner (Fly combo as seen by clockwork, which I’m working on now)
So I’m getting the loop down without too much difficulty, but I want to learn his most damaging by himself combo, and his most damaging with assist. Is it has loop in the corner that ends with level 3? Just not sure what those last two are, I’ve heard legends of a one mil combo with one assist and one bar.
I just do the loop after last launch I do j.m,j.f+H,j.s otg H, M rocks lvl 3 gets over 1mil easiest combo with no assist for me. can change lvl 3 for sphere flame does abot 700k
I may have missed this from some combo video but you can do anywhere on the screen finish a combo with launch j.M pause j.M f.H S. then end with an otg combo. This lets you from about one dash length from the corner you can do one bukloop, then two reps of the above to put them in the corner, and end with a ground otg into super. You can get about 777k with this or 830k if you do a full dive m h S before the combo.
I think the first page definitely needs an update, to include duck strongs combos as clockworks flight combo.
Clockworks flight combo is purely for gaining meter after a TAC, other than that, there’s no merit to it in conjunction to his usual combos. So if you add that, be sure to add it as a side note.
It probably pushes people closer to the corner better than most any combo Doom regularly uses so I would say there’s merit to it considering Dr.Doom can nearly 100 percent Wesker if he lands a hit close to the corner.
I believe you can actually do some corner loopage after the flight combo to get some decent damage
this. I got his fly loop down, currently working on the magnetic blast loop, but the hyper grav and roms on pad are impossible for me to do. D: I need to get myself a TE ASAP.
Man i sit at home and i figure out all this shit on my own (except bucktooth) and then i come here to be all “yo dawgs i got some info!” and half of it is already here! Ohwell.
Here is the ultra low quality vid i did, seems pointless now xD YouTube - Doom Combo - Bucktooth extend + foot dive loop
having troubles with the bucktooth loop after the down forward airdash and jumping m, i cant seem to land his crH. any tips?
You’re either waiting too long to do j. after the :s: or you’re doing the j. after the addf too early. The first j. should be as early as you can pull it off and the j. after the addf should be as late as possible. Besides that, you’ll basically just have to try to find the exact timing in the lab.
aight thanks man
i’m gonna work on a potentially more reliable version of buktooth loop that involves dash-jump cancel. ill see how well it works
My intuition tells me dash-jump cancels would be harder than Buktooth loop, but if your efforts say otherwise, let us know!
Doctor Doom bnb combo guide
I made a video and wrote a little guide thing about Doctor Doom bnb combos since I have been hearing a number of people asking about it lately both online and in person. I am no expert player, but these are the kinds of combos that I rely on and hopefully this post will at least give new players a solid foundation to build on and maybe give some other players an idea or two. The goal of this post is to provide reliable intermediate level combos that aren’t too heavy on execution, so things like flight mode j.M loops and wall to wall carry combos will not be covered. I will also not go into great detail about DHCs and exchange combos because they are team-specific and you need to experiment and find them for yourself.
Most of Doctor Doom’s bnbs consist of variations/combinations of a few main combos. In this post I will primarily be covering two combo paths which I will refer as the Midscreen Loop and the Corner Loop. All the combos listed here are in one video, arranged and labeled by section with links to each section placed throughout this post.
Being the lazy person that I am, I will just be posting notations for the basic combo paths and assuming that people can use their knowledge and common sense to figure out the rest by sight. If someone would like a particular combo notation or if I made something confusing let me know and I will try to clarify.
The Midscreen Loop:
The basic Midscreen combo. This is what you will need to use if you cannot push your opponent into the corner. If the Midscreen Loop carries the opponent into the corner, it can easily transition into a couple reps of the Corner Loop for more damage, which I will cover later. If you aren’t 100% sure where the corner is relative to your starting position, performing the Midscreen Loop and waiting to see if you hit the corner is a valid strategy and won’t completely butcher your combo damage. The Midscreen loop also works in the corner so learning it first will give you a reliable starter combo for all situations until you have mastered the corner-specific combos.

Notation:
:d::l: :d: :d::h: :s: j. j.:f::h: airdash:df: j. land
:d: :d::h: :s: j. j.:f::h: airdash:df: j. land
:d: :d::h: :s: j. j. airdash:f: j. j.:s:
Potential enders:
Full combo into air super
Shortened combo into sphere flame
Shortened combo into level 3 at midscreen
Exchange combo into whatever
There are a number of ways to make the Midscreen Loop easier by substituting some different normals in the final relaunch. I have recorded some of them and will hopefully get a video link to them soon.
The Corner Loop:
This an extremely damaging and easy combo that only works in the corner. Hitstun scaling will require you to use an assist for a sphere flame ender, but you can cut the combo short by one repetition if you have no available assist. Ending in a level 3 super does not require an assist, but using one can add extra damage to the combo and allow you to add an extra attack like heavy plasma beam for even more damage. Experiment with your assists to see what works best.

Potential Enders:
st.H into sphere flame with various assists
Shortened combo into sphere flame without assists
Full combo into level three with or without assists
The Midscreen Loop into the Corner Loop:
If you aren’t right in the corner from the very beginning of your combo you can still reap the benefits of the corner loop by adjusting mid-combo from one to the other. Starting from the Midscreen Loop there are two ways to do this: after the first repetition of the midscreen loop, or after the second. If you hit the corner before the final repetition of the midscreen loop you can still do the longer version if you wish, it just does a bit less damage.

Examples show transitioning from Midscreen to Corner loop from the first or second relaunch of the Midscreen Loop. I have left in the pre-combo resets and dummy pushing to show approximate distances for when this combo is possible
Potential enders for these combos are the same as the regular corner loop
Throw Combos:
Comboing after a throw generally means going into a Midscreen or Corner Loop. The throws scale the damage pretty hard and have harsher initial hitstun scaling, so you generally have to cut your combo down by at least one repetition. It is still possible to get some solid damage off of throws with Doom, especially in the corner or with xfactor/DHCs.
Throw combos can be ended in mostly the same ways as the basic combo paths they lead into, I am including some basic enders to make the combos less boring to watch but you can do whatever works best for the situation.

Back throw midscreen
Back throw into corner
Front throw into corner
Back airthrow midscreen
Front airthrow into corner
There are a lot of slight variations to combo off of a front airthrow in the corner, much like the different ways to do the second relaunch in the midscreen loop. The main goal is to catch them in the air with a falling j. and then land and juggle them with whatever attack you choose, then combo into a launcher and go straight into a shortened Corner Loop. In my video example I used a very easy variation as timing can be a little tricky with the hitstun scaling from the throw.
Xfactor Combos:
With Doom, a great place to use xfactor is between one of his ground normals and st.:S:. You can do this for the first launcher of a combo, or wait until a bit later for a later hitconfirm (and a slightly less damaging combo).
All examples are shown using level one xfactor
www.youtube.com/EWjOawa8MjE#t=6m16s
Early hitconfirm xfactor combo
Late hitconfirm xfactor combo
Back throw xfactor combo with amazingly difficult execution
I will be editing and cleaning up this post but the bulk of the information should be here already
space reserved for future expansion if necessary
if anyone can think of anything that should be added let me know
Aw man, I was thinking of making a long ass Doom tutorial, but now I think it would just be a little redundant.
Hehe, nice vid just the same, I like how its to the point and everything you mention is practical and worth knowing.
I might make one anyway, just one more out of a bazillion Doom vids, lol.
