Help finding toy from late 80s/early 90s
 

I for some reason have been trying to remember the name of a certain action figure line from the late 80s or early 90s. As a child it was a cool action figure in the commercials, but not sure if it had a cartoon? Anyways all I recall is the commercial which went like this:

Kid is playing with this action figure, a GI Joe type, but the catch is they either fit into a bio mechanical like diving suit, or it is like attached to the figures back and flips over the figure, I think ya the earlier one? Then the zip around under water to battle evil.

I hate that's all I remember, I have searched the net on and off for a few years hoping to randomly come across the answer but no luck, so I found my way here hoping someone can help me.

80s Commercial - Centurions Max and Ace - YouTube
was it centurions? check out the commercial...
took me a minute to figure out the figure line name but i think this is what you are looking for...

could it be the centurion's maybe?

*edit* you beat me to it :P

I'm pretty certain that's it! Man, seemed a lot cooler when I was little, lol. I actually saw those toys when googling, but wasn't sure if it was it.....

Big thanks guys!
