Hybrid Killingham makes no sense.
First, because we were already seeing his apparently hybrid form: Qilin isn't bipedal nor has human torso and legs, hands and feet.
Second, because both forms of Killingham don't feel like the same person. So far, Killingham looked laid-back, a bit clumsy but elegant; but this new form looks vicious and aggressive.
And third, because this new form doesn't look at all like a Qilin: there's no mane, there's no single horn, there are no whiskers, there are no eyebrows. There's nothing you identify as Qillin's.
A seriously bad design overall and a significant downgrade.
