Not precisely an Evil Overlord, but Dr. Frankenstein has many successors:
A monster I shall make, of many parts; I'll take my fear to fail, and my hope, My anger at the needless social arts, A vow that I'll no longer simply cope. Beneath the dark and circling brows of storm, I'll mix in words that waken it to kill. In all of passion's fire, keep it warm, And waiting for the lightning, hold it still. And when the spark of life has bridged the gap, Twixt earthly body and the airy soul, I'll what I've wrought in mortal vessel wrap. I've found for it a simple child's doll. Who plays with this will see their life destroyed — will live in fancies, of the truth devoid.
