Here's some starters.
First and foremost, he is indeed, a male ninja so he already has awesome normals. He walks faster than any character in the game which enables him to extend juggle combos a bit, enabling to score right around 50% from a JP to popup on just about anyone. You should be able to get at least 3 juggle jabs after a pop up easily on anyone, which many other characters can do, so try for 4 on many, and 5 on some (Jax, Stryker, Sub, Male Ninjas etc). The fact that he walks fast essentially allows him to get 1 or 2 extra juggle jabs on any character, so don't treat as if he should be able to juggle anyone across the screen. He has Kano's combos so he has a variety of options. He can do the low starting knee lift pop up the ground, or swap to the 4 hit pop up on a jump in and gain significant damage.
On certain stages you can take advantage of his lack of color. He doesn't take chip damage on combos after the first hit which is a huge benefit, on top of that he takes approximately 75% of normal damage, ie: uppercut = 16% vs 21%. The fact that he has no special moves really makes you focus on normals, combos, and relaunch juggles, since he can relaunch everyone. Take advantage of what you can. His greatest asset is the low damage.
Basic combos:
HK, LP, aaHPHP, aaHP, JK/HK/ or LK - 6 hits 31%/30%
JPS, HP, HP, D+LP, DHP, aaHPHP, aaHP JK/HK/ or LK - 9 hits 48%/46%
Basic Corner combo:
HP, HP, D+LP, DHP, JK, RH, LK - 7 hits 44%
Advance combo example:
JPS, HP, HP, D+LP, DHP, aaHPHP, aaHP, aaHP, aaHP, HK 11 hits 54%
Advanced corner combo example:
JPS, HP, HP, D+LP, DHP, aaHPHP, JK, RH, HK - 10 hits 63%
Male Ninja Teleport Punch punisher:
aaHPHP, aaHP, aaHP, aaLP, HK - 7 hits 45%
So mess around with extra jabs using run to cancel them, the least jabs you can get is on Sheeva (not worth trying more than 2), the most on Jax (up to 5 HPs and 1 LP within reason), everyone else is in between. Also notable, Liu, Shang, Kung, etc, are difficult to get multiple juggles on.
On a side note, I think the damage Noob takes would be great if all the characters took it. It would be somewhere between UMK3 and MK9 damage, extend matches a bit, and make it a little harder for characters who rely largely on pressure mistakes like Kabal and Human Smoke.
