--Heavy D!

normal version:

standing D -> f+A -> qcb,hcf+C (9 hits)

opponent cornered:

standing D -> standing A -> f+A -> qcb,hcf+C (10 hits)

crouching B -> standing A -> f+A -> dp+A (7 hits)

Heavy D! has the most chain combos in KoF98, so it's best to experiment a bit with them, it's awesome what he can do.

--Vice

standing A -> f+A -> qcb+C (3 hits, 2 rush hits)

standing A -> f+A -> hcf+B (3 hits, 2 rush hits. If you feel brave and your opponent isn't the quickest, you can immediately follow it up with a super-jump towards the opp. and pull off her qcfx2+P DM very shortly before landing)

jumping C -> qcb+K (in air) -> hcbx2+K (about 5 hits, no rush hits, but all moves combo/connect)

--Joe

jumping A -> f+B -> dp+B (3 hits)

crouching C -> f+B -> qcf,hcb+C (13 hits)

jumping B -> standing C -> tap C rapidly -> qcf+C finisher -> qcf,hcb+C (pseudo-juggle, 11+ hits, this is a very tricky and risky combo tho, only the last hits of the DM connect. Don't pull it off against skilled grapplers)

--Mai

jumping C -> qcb+C (in air) (2 hits)

f+B -> standing C -> dp+B (3 hits, timing is tricky)

f+B -> D+C -> qcfx2+C (3+3 hits)
