Karma, karma, karma, Khameleon...
Reiko/Khameleon is interesting.
You can combo from the command throw using Kitana's lift.
Command throw, f+kameo, jumping 2, 3,4, EX slide, standing 3, tackle.
The damage highly scales. On the bright side, though, Khameleon always disguises as Mileena after this combo, which means that you have access to the 18 frame overhead. 3,4, EX slide, jumping 2,1,4 works after the overhead for 30% of damage.
Khameleon now disguises as Jade who improves your zoning with the glaive.
Ideally, you want to be Kitana and Mileena up close because of the launching command throw and un-reactable overhead, respectively. You want to be Jade from far away because of the glaive and glow. However, sometimes the rotation is off, and I am struggling to "switch", for the lack of a better verb, to the appropriate disguise. Perhaps such is the nature of Khameleon or perhaps I need to do a better job alternating between the three disguises.
NRS did a really good job with this kameo. I initially thought that she was going to be as bad as Shujinko. "Random buffs" and "per chance" designs tend to be unviable in fighting games. Top tier or not, she is fun to use and explore.
Speaking of top tier, Reiko/Tremor still appears the way to go because of the damage output, extra health, and consistency.
