Also, if you'd kindly look nine rows down, second from the right, you'll see Hitmonchan, who is damned near literally just a boxer with a funny head. Also Jinx, Mister Mime, and Machamp.
The defining aesthetic drift of the generations is a matter of complexity, and nothing more. Even so, Pokemon are still overwhelmingly two to four colors, what we've gotten is increasingly intricate shapes, which will naturally have the frequent human archetype be reinforced by the additional degree of detail.
As for "fixing" Kleavor, the first order of business is putting the dark stone on the head over Scyther's head shape. Small exposed area between the middle spike and two outer ones, keeping the "face with head-knot" shape, but with the "knot" being a slightly more forward spike and the "face" simply being a ridge around the front of the head.
Secondly, start with turning the axes into rectangular wedges. Then, make them slightly shorter than the forearm, while making the forearm about a third shorter. Finally, add a light portion marking a wrist joint blocked from moving backward by the "axe", making it into a full mantis arm structure with stone-age axes for "hands".
Thirdly, focusing on the legs, add a small amount of the dark stone just above the feet while moving the shins closer to the middle of stone portion. Have the front edge of the "hip" become the dark stone, extending about halfway up the outside and with a spike all the way along the top.
Finally, for the upper torso, re-arrange the shoulder-guard to a spiral arrangement leaning inward towards the chest, reducing the range of movement interrupted by spikes and allowing the arms to move more fully forward as follow-through, alongside adding a dark stone spike along the upper wing to mirror how Scyther and Scizor have carapace there.
