The bird-like Valvatos appears to be a further development of Zoanoids like Malcult, Casvarius and Citiciss. Its arms have been elongated, like theirs, but this development appears to have reached its extreme: its body has the proportions and flying ability of an eagle or hawk. The only real concession to the humanoid form appear to be two human-like clawed hands on the wings. After Devold, Valvatos is the lightest of the flyer types.
