What is the Easiest Way of Defeating Stockman?
 

Okay, I get SO frustrated with Challenge mode. One moment, I can barely get past the Elite Ninjas, then I FINALLY beat Hun (thank goodness for having 99 Exploding Ninja Stars, Michaelangelo can easily take out four boxes and collect the items)... but I've been stuck on wondering how to beat Stockman and that huge friggin' machine of his. You REALLY have to get deep into Challenge Mode to get to this son of a...... gun!

Anyway, this guy kicks my ass every time, and I have no idea how many lives I sacrificed facing this son of a...... gun in Story Mode. So please, what is the simplest and safest way of defeating him? I MUST complete Challenge Mode.

Use your jump attack. make him eat your feet until he dies. I posted how to beat everyone in challange mode in another topic Ill find it and post it here
EDIT:
Here I found it this worked for me it should work for you good luck
Here are some tips
SAVE ALL NINJA STARS YOU GET!
To beat the gunner fast jump behind him and waste him DONT HIT THE SHEILD that’s the key
For Quarry just kick his butt his not hard
Razor fist do the same as with the gunner but after like 3 hits jump back because he'll swing back and try to hit you with his head
For Baxter just dodge his attacks and when he’s open jump attack him
For the elite ninjas just dodge like crazy run around and do the run and hit attack a lot, watch the one with the spear he’s annoying
For Hun use the ninja stars you’ve saved
For Shredder Same as Hun and jump and run around if he charges you. Don’t just throw the stars at Shredder though because after one or two he falls down and then they don’t hurt him so time them
For Saki just waste him with stars!
For Yoshi use the remaining stars if you run out then run and do the charge attack
I suggest highly that you use Don he has a great reach so you don’t have to get close to hit the enemies you can hit them from a safe distance
Hope this helps man and good luck

THANKS MUCH!!! I'm definitely going to apply this. But Michaelangelo is the only person I could use that could go this far. I'll see what I can do.

seriously i dont know how i beat that game.. if it wasnt for the thing that takes out half the life points with the push of one button i wouldnt of been able to beat oroku saki at the end.

Donnatello is the one that I used first in challenge mode, thae hardest one to beat in challenge mode for me was hun, for stockman I just jumped and hit him in the head when he put his arm up to shoot them fireballs and ran like shell so the fireballs wouldn't hit me and just did that repeatedly until he was beaten.
Now as for yoshi , fire shurikens are the easiest way to get him.

Yeah, I finally beat Challenge Mode not too long ago... maybe a week ago. I took the advice, but I messed up Stockman with Mikey. He's got quick combos!

Yeah he does Im just better with Don for some reason
