using this fight(
http://www.youtube.com/watch?v=pZ9gt1oe4Zs) at 5:07 as an example, i do a cargo-release to Jab Combo. Outside the ness/lucas dept., the jabs would not be 'guaranteed', but i argue little to nothing is guaranteed, and the tactic is still useful. In fact only a few characters can slip outside the jab range if they're DIing away (which noone does because they're either mashing or holding Up)
when someone is cargo'd they just want to get out, and often do not plan what they should do if they do happen to get out: which is either rolling backwards are beating DK to the Jab...
if they basically do anything outside shielding or jabbing (or UpBing if ur marth, mk, etc), DK's jab is likely to sneak in - and continue into the 2nd hit or bait them for a grab. The Cargo release itself deals 6%, and if u sneak in a pummel headslap for 3%...= You have a quick 20% for the jab combo, or a 'grab-reset' gimmick so to speak.
His UpAir is underused. it can legit-combo off b.air, And its his quickest, best option to OOS someone above/infront(even standing oponents as short as toon link get hit if done early enough!) Fresh, it kills ~100-140%.
Hit someone w/ an upair at low percent and UpB (before landing) followup for 40+%.
UpB can intercept alot of combos, like Peach's D.air, but it needs be tested for all multihit moves. Help is needed on this, such as Can DK DI-UpB punish from getting hit by Snake's N.air?
also sexy:
DK can grab release Wario to (turn around) B.air.
When someone is b.aired, if they DI away, it usually leads to more b.airs, if they DI up and away a DJ b.air can pursue and often lead to another. If they DI upwards, you simply immediately followup w/ an upair [to uptilt, at low percent].
This should be his dominant grab-release damage racker, as it can combo into itself and/or upairs from low-mid percents. (unless u have, and dont mind nerfing, you're giant punch for the 28%.
At starting percents, release to SH double b.air can combo into a up/f.tilt or even a grab!!
example: grab, release, b.air-b.air, grab, release, jump upB (~70%!)
u could go for more b.airs too if u want, or release to SH UpAir-UpB at low percent, or full jump UpAir-UpB at mid.
