Filmation Star Trek Cartoons
I saw that Paramount+ has the old Filmation Star Trek cartoons from 1973 / 1974.
I began re-watching these episodes.
Yesteryear was one of my favorites as a kid. Because of a mishap while using The Guardian of Forever, history is changed and Spock never lives to reach adulthood and his mother, Amanda, is also no longer alive. Isolating the pivotal point where time changes, Spock travels back through time to meet his family and his childhood self ( whose voice sounds like that of Linus from the Peanuts cartoons ) acting as a relative on religious travels.
