Rebirth Fact #213

The Ultimasaurus Rex was created by InGen as a backup plan to contain the Indominus Rex should a accident happen.

However when the events of jurassic world happen,the Ultimasaurus couldn't be released as it's appearance would spark more panic.

However when the Ultimasaurus was discovered it was suggested it would be released into the savage land where it would live out the rest of it's life.

Unfortunately,while it enjoys it's life in the savage land the Ultimasaurus couldn't help but feel to try and kill the Indominus Rex more specifically a gen2 version of the Indominus Rex created by Dr Animo who now is relocated in the savage land with other hybrids animo created.
