In Gen 2, there are seven Pokemon that evolve via high friendship: Pichu, Togepi, Cleffa, Igglybuff, Eevee, Chansey, and Golbat.

But in Gold & Silver's 1997 demo, the friendship mechanic didn't exist -- all these Pokemon evolved by leveling up (except Togepi, who didn't evolve).

Galarian Ponyta & Late 90's Shinies:

Ponyta & Rapidash had Shiny colors unique to Gen 2 -- their Shinies were changed in every future generation.

Interestingly (and probably coincidentally), recently-revealed Galarian Ponyta bears a strong resemblance to Gen 2's Shiny Rapidash.

The Evolution of Ivysaur:

From his creation around 1990, to his original Japanese sprite, then his first artwork by Ken Sugimori -- Ivysaur was heavily revised during the early days of Gen 1.

This Ken Sugimori artwork was featured on the Japan-exclusive Carddass collectible card set, circa 1997. Backgrounds photoshopped out and replaced them with white.

The Evolution of Nidoqueen:

Nidoqueen was created as a bulky reptile, then was later revised with some serious weight loss and a set of fangs. But ultimately, Game Freak settled on a de-fanged design for Nidoqueen.
