One of the things I’ve heard from almost a dozen FAQs, and reviewers is that certain characters are better in either power or speed. While this is true for some characters, almost everyone uses the same two examples “Zantetsu for example would be better in speed due to his quickness, while Shigen would be better in power due to his slow speed and lack of combo ability”.
This isn’t true.
Zantetsu on power is able to link:
Crouching C > Crouching C > Standing C > QCB B > QCB HCF AB > Jumping QCF A X 2 as well as:
Crouching C > Crouching C > Standing foward C > F B F C > QCB A > Jumping QCF A X 2
On power, these combos do a sickeningly large amount of damage.
Also for Shigen: He has insane damage potential simply because of the reach of his standing B, which makes up for the slow speed of his attacks, and you can indeed link many of his moves on speed; the secret lies in chaining his QCB C x 2 from a light or hard slash, and then ending with either another tackle, his claw, the C version of his dashing throw, or his anti-air grab.
If you choose to use the claw (anywhere) or the tackle (in the corner), you can follow it up with a running throw that’ll actually scoop them right off the ground.
