Sea Clamp was the end result of Cicadacon's early experiments. Following Cicadacon's rediscovery of his own first generation origins he set to work studying his "fellow" Decepticons and found other dormant Cybertronians ready to be awoken. About the only traits Sea Clamp retained from those days are a sense of fierce loyalty (except now to the Cybertronain cause) and a distinct lack of expression. Only Ramhorn is able to get a reaction from him and it is usually violent.
He maintains a fondness for the past and many of his former Decepticon comrades and has encouraged many, including Ravage, to follow the will of the Council rather than the Decepticon cause. Sea Clamp thrives working in secret, on clandestine missions and with hidden agendas, which is why his place operating within a secret council under the noses of the Decepticons and living a dual existence suits him perfectly.
