Charlotte dominates the air. She has a fast jump, amazing air normals, and a great anti-air with Power Gradation ( :dp: + slash). On the ground, poke with stand :snkb: , Violet Thrust ( :qcb: + slash), and Tri-Thrust ( :qcf: + slash). That’s the extent of my knowledge on her.
Jubei’s :qcf: + :snka: / :snkb: are awesome projectiles. They go really low to the ground, so they slides under most other fireballs and even a lot of reflectors. The :snka: :snkb: version is like Geese’s Double Reppuken: first swing absorbs projectiles, second swing sends a fireball, which chips three or four times. Jubei has three counters: :qcb: + :snka: counters crouching normals. :qcb: + :snkb: counters standing normals. :qcb: + :snkc: counters jumping attacks. His :snka: and :snkc: counters will counter special moves regardless of whether they hit high, low, or medium. His :dp: + slash attacks make him invincible while he is dashing. His :snka: :snkb: normals are all very slow and cumbersome, and his :snkb: moves, while good pokes, are a little on the slow side.
Please feel free to correct me on anything, I don’t use either character much.
EDIT: Also, what are some good anti-Kusaregedo tips?
