I learned how to Bdacus (
http://www.youtube.com/watch?v=WcDLKBJyQzk ), if you press up on the C stick, you'll buffer a Dash attack. Today after I learned some characters can't jump from B-throw and Fthrow (Bthrow> Fthrow though F throw has better follow ups) and but I only find it possible to Bdacus from Fthrow, some characters are forced to land, others have the ability to jump near ground, it doesn't work at all for some... these are not true combos. These arent useful on character that are sent flying as they can DI away from you. The Bdacus can be used to rack up damage and dash attack can lead into juggles and strings.
I used two controllers to test this
Forced Landing
Near Ground
Barely Works
Doesn't work too well
Doesn't work at all
Fthrow
Mario - Bdacus/? - Can (barely) escape. Just jump.
DK - Bdacus - dash attack only works if he didn't jump- He goes a bit high but it can still be pulled off
Link - Bdacus/Dash attack - It works well on him... lol
Samus - ?Bdacus?- Can escape if she wanted to. Just jump.
ZSS - Dash attack/Bdacus - you really have to make sure you do this quickly as her jump gets her out of range quickly
Kirby - Bdacus - I honestly expected this to completely fail, but the Usmash's first hit can knock him into the third hit, otherwise, it fails.
Fox - Bdacus/dash attack/Grab? - Fox has to go through 4 frames of hard landing lag giving us more time to attack, if he shields then you can get a grab
Pikachu - Dash attack?/?Bdacus?-This thing goes way too far, Dash attack barely gets him and usually will miss. The Bdacus will be late and Pikachu can escape before you can really move
Marth -Bdacus - Marth (barely) escapes. Just jump. Dash attack will give a red spark(don't know name) if he doesn't move at all.
Gaw - Bdacus - Dash attack will miss since it goes too far and Gaw can easily counterattack or jump away
Luigi - ಠ_ಠ - He goes too far for Dash attack and once he flips, he's out. BDacus won't won't reach him in time
Diddy Kong -Bdacus - he goes too far for Dash attack and Bdacus will only work if diddy doesn't buffer a jump
Zelda - Bdacus - it all depends on what Zelda does after hitstun. As long as she didn't jump, then you can get the hits in
Shiek - Bdacus/dash attack- Same as Zss
Pit -?Dashattack?/Dacus - Same as DK
Meta Knight - Dash attack.../Bdacus - Bdacus can hit MK out of his jump, and dash attack won't hit MK unless moves towards you
Falco -Bdacus - He goes to far for dash attack. He can counter Bdacus though... if he expects it...
Squitle - Bdacus - Most light characters just go too far squirtle is not an exception. BDacus works but only if squitle doesn't jump
Ivysaur- Bdacus..../?Dash attack? - he flies too far for dash attattack, in order for it to work, he must move forward. Bdacus only works if ivysaur doesn't jump.
Charizard - Dash attack../Bdacus - Same as DK, you can be counterattacked... if expected. Dash attack will miss if Charizard moves back.
Ike - Dash Attack/Bdacus - I prefer dash attack as it is faster and Ike has very little time to react to it. I'm not to sure about this but i think if Ike dodges, you will still hit him.
Snake -Bdacus/Dash attack- Use Bdacus, Dash attack doesn't send Snake far at all.
Peach - ಠ_ಠ - You can try Bdacus but she flies too high, she'll only get hit if she doesn't jump or float
Yoshi -Bdacus - Yoshi flies too high for dash attack, and with it's mobility, it can easily move out of the way of Usmash. It will only hit if yoshi doesn't move too much or DJ.
Ganondorf Dash attack/Bdacus- again, I prefer dash attack. If ganon ends up landing, he'll go though 5 frames of hard landing lag. It doesn't make much of a difference
SoPo - Bdacus- Popo really goes pretty far but not that far. Bdacus will hit as long as Sopo doesn't move away or jump
King Dedede -dash attack/Bdacus- Same as meta knight... lol.
Wolf - Dash attack/Bdacus/...grab... - unlike fox, wolf does not undergo hard landing lag so getting another grab would be harder. He lands just as Dash attack hits. He has the ability to shield Bdacus.
Lucario - Bdacus - He goes too far for Dash Attack and Lucario can counterattack your Bdacus
Ness - Bdacus - Same as Lucario
Sonic - Bdacus - He goes low enough for the initial hit. Basically, same as Kirby
Bowser - Bdacus/Dash attack - Just like Ike, he doesn't have many options, but once he jumps, he's out.
Wario - Bdacus - Doesn't work to well since he goes so far, and is out of hitstun when in midair. Just as long as get gets caught in the first hit, it should be fine.
Toon Link Bdacus - Same as Wario
R.O.B. - Bdacus - Same as Wario
Olimar - Bdacus - Same as Wario
Captain Falcon - Bdacus/Dash attack - It's possible for CF to escape from dash attack if he jumps away
Jigglypuff - Bdacus - Same as Wario... meh.
Lucas - Bdacus - Same as Wario. I wish i could say more but it's just so stale.
Yeah, I guess I created another Link gimmick, haha.
I wasn't too sure where to post this, I hope it's the right place
