Sub-Zero
Scorpion
Superman
Jax

Sub-Zero-Ice Nugget DB2 (worst, because you can see it coming and leaves you open due to long wind up and recovery)

Scorpion-Hellfire Summon DB2

Superman-Ground Pound (easily the best) DD4 (pro moved for infinite)

The Joker-bomb(best non-broken unblockable)
-short range FF2,
-mid range FF3
-long range FF4

Jax-Ground Pound DD4 (same speed as superman's but no infinite pro move)

captain marvel-SHAZAM lightning DB3

Lex Luthor-Flame Thrower BF3

Darkseid's Omega Tremor-DD4 (two htis, one just before the tremor hits, close range only, then the tremor, my favorite ground pound move)

Raiden-
Vicinity Blast (hold 2) DB2
Lightning Bolt (hold 1) DB1

That's all, technically the square wave punches are unblockable since you can't block in the air, but they can be breaker'd

scorpion
sub zero
superman
shazam
shang stung

I think that's nearly a complete list. Except that Luthor's Flamethrower is blockable.

To finish the list.

Shang Tsung's Body Switch - D B F 1

Kano's Pro Move Cannonball - B F 4+Block (hold 4+Block)

Technically, yes...Tsung's switch is unblockable, but it's not really an "attack".

It's kinda like Raiden's teleport, to an extent...although I will add Sub-Zero's DB1 Icy Counter as an unblockable...kinda...

All of the characters have them. Just learn them from playing its more fun =]

They consist of crouch unblockable moves to standing unblockable moves. Aside from the special moves there are unblockable moves like kicks and punches done by holding back and the punch or kick button of your choice.

i like the new game mortal kombat vs dcu very much
