Look here and scroll to the additional information and it will show you which characters have the link and see which ones you have

Just a quick glance, your SSJ3 Vegeta is the only one I see that has it. Phy+Agl SSGSS Vegetas, Teq Future Trunks, Vegito, Omega Shenron, Ultimate Gohan, SSGSS Kaiokin Goku, and SSJ2 Gohan will have it once dokkaned, so you should work on these characters before trying Blazing Potara.
