I was thinking and been pressing for something for a long time. A semi-feathered male Velociraptor that was part of the Raptor Squad, but was exiled to Sorna since it kept challenging Owen as alpha male.
Here's my idea.
Blue has a twin/slightly older brother. Since male monitor lizards, like Komodo Dragons, are larger then females. This male raptor will be slightly larger then then the females. This one will also have golden eagle or Philippine eagle DNA which explains his feathers on the body, arms, tail, and neck. At first he was fine...but when he got older he realized that he had no competition...except for Owen. And the two kept on fighting. Worse, nobody took away his reproductive abilities and those that tried when he full grown failed and were badly wounded and almost died. After years of the male raptor and Owen fighting, and much debating, it was decided to exile him to Sorna since Blue might rebel against Owen if he killed her brother.
When they get to Sorna. They realize that the male raptor, named Omega since he was the first and last male Velociraptor bred on Nublar, he has his own pack-which is also the largest on Sorna after it was made out of outcasts from other packs-but he also has his own kids, and remembers how he was booted out from Nublar.
The undisputed dominant predator of Jurassic Mainframe.
