The request is Titan Fist combos but with each combo in a specific key, and only 4-hit combos.
Z > Auto Mortal Fist (4-hit Blue combo), with finalization on Z
X > Auto Twisted Metal (4-hit Yellow combo), with finalization on X
C > Auto Titan Surge (4-hit Red combo), with finalization on C
Exora has a similar addon, but for 7-hits, and the same skill on ZXC just changing color buff between them, so i think is possible to make this one.
