Cobra CRAB w. Sea Bastion - Delta Vehicle 19.99$ MSRP
A force to be reckoned with! The heavily armored CRAB is Cobra's sea dreadnaught. Armed with machine gun turret and two launching missiles! Includes Cobra pilot Sea Bastion. Other figures sold separately.

From the desk of Bucky:
Sea bastion was one of the first brainstormed characters that popped into mind while thinking about another project a couple days after new sculpt was finished up.
The name was a play on Sebastian, which is the crab from the little mermaid, which I was watching with my daughter while brainstorming other ideas. I thought it'd be a fun character to do and give him a boat called the crab. A side note, that head, minus the hair, has been done for years, and was sitting in a bag that was supposed to be a voltar that was never completed.
The crab was one of those clearance price finds at tjmaxx I think. It was on sale for around 8 bucks, and I picked it up knowing someday I would do something with it. That was late 2012. Better late than never.

The filecard by G1Trekker makes the mention of a connection with Shipwreck. Shipwreck is an orphan, and Sea Bastion is an old man. What is the connection here? A built in easter egg for Resurgence!
