it seems to me that the vehicons are intended to be soldiers for any theater of war yet we are missing a vehicon for water conflict. Granted we haven't had need for them just yet but i would think that we would have seen them on the 'cons warship somewhere. as far as the character model for them goes the animators could just use the jet model alter the wings(smaller and with a few propellers) and a smooth alt mode front would do the trick. also while i'm on the subject of water, why, with so much of the planets surface covered in water have none of the relics been in the ocean? they arrived millions of years ago "scattered across the planet" so they only appeared in the 1/3 that was dry?
