Huh…

Looks like that image specifically is from a fan-made version of Phase II, but yeah you’re spot-on.

I knew about Phase II, and that elements of it were merged into TMP and TNG, but I only remembered the triangular Enterprise concept that was later the basis of Discovery.

This all sent me down a rabbit hole where I learned things like Xon (originally a replacement for Spock) became Saavik, and Decker and Ilia were the basis for Riker and Troi.

Thanks!

Oh, what a terrible day to have eyes
