Midscreen I've been doing:
c.LK, MK, HP,
j.HP, ad, j.LK, j.HK,
(otg)c.LK, MK, HP,
j.LP, j.LK, j.MP, j.MK, HK Hairball, dash cancel,
LP, MP, c.MK, c.HP, HK Hairball, Fenrir
7.4k-ish damage. Against someone like cerebella and double, you need to do some minor modifications like removing the MK from the otg chain.
The universal corner combo I use is:
c.LK, MK, HP,
j.HP, j.HK, HK hairball, adc, j.MP, j.HK,
MP, c.MK, HK, HK hairball,
(Otg) c.LP, LP, LK, MP, c.MK, HK, HK hairball, fenrir.
Does something like 7.9k. Has worked on every character.
Against Bigband in the corner:
c.LK, MK, HP,
j.HP, j.HK, ad. j.LK, j.HP, j.HK,
c.MP, TK air HK hairball, dash cancel,
c.HP, HK hairball,
(otg)LP, LP, LK, MP, c.MK, HK, HK hairball, Fenrir
