Transmetal Predacons have organic features, though not as "mammalian" as the Maximals. For example, Terrorsaur's hands and legs look organic, Megatron has a kind of leathery/scaly reptilian aesthetic, and Rampage's "skin" looks like a crustacean carapace, Tarantulas' hands and legs look fibrous (and he has organic like claws on his fingertips), Scavenger's shoulders, thighs and feet resemble a chitinous insectoid look etc.
