So I’m pretty sure people have explained it already, but in case you’re unsure still:
Legendaries with just normal white backgrounds are normal legendaries. Think T-Rex.
Legendaries with golden beams shooting out of them (lol that’s the best way I can explain) are Tournament Legendaries. Dracorex and Gorgosaurus are tournament legendaries. You unlock these at the last battle stages in the game or by reaching Dominator in tournaments. They’re stronger than legendaries.
Legendaries with golden hexagons are VIPs. These are insanely strong, and as such, have no hybrids. Thylacosmilus is a VIP. You get these in Loyalty Point packs and I think maybe Trade Harbor later? You cannot unlock VIPs or buy them with DNA in the market.
Hybrids with just the golden border and some golden hexagons are normal legendary hybrids. Their highest rarity component is a normal legendary. Indominus Rex is a legendary hybrid.
Hybrids with purple shiny backgrounds are tournament hybrids. These are just like hybrids, but their highest rarity component is a tournament legendary. Yudon is a tournament legendary.
