Micro Machines Submarine. It could launch torpedos and ICBMs. 

There was also a Chinook and a C130. I vividly remember owning the former, but only sort of recall the latter. Neither was as amazing as the submarine.

Then there was this, which was so rad.

I have vivid memories of finding it on clearance at K Mart, begging my mom to buy it for me, then going home and playing with it while watching Live and Let Die on TBS during one of their Bond marathons.

My life peaked at a very young age.
