I'm not sure how well this concept will do, as it's not overtly weird, or a moviefied take on a G1 character. Anyway, this design started out as "What would a movie version of Cybertron Thunderblast look like?", and graduated into some curious thought experiment. From a boat, I thought perhaps a smaller robot with a jetski altmode instead. Then I considered a robot with an aquatic mode might be limited to that environment in the movie way of doing things, and I preferred not to do some kind of mermaid-bot, so I started looking around at various amphibious vehicles and came up with this quad bike which converts into something like a jetski. It all (sorta) fell into place from there. She was given the name "Tsunami" as there wasn't too much in common with Thunderblast any more, not to mention "Thunderblast" being kind of a silly name for a feminine semi-aquatic TF.
