This is how I won against an alpha Rex so I was looking for a male spine to breed with my spina colada my highest spino and I see one of these I rush to my base and grab both my female spinos my 3 Rexes and my Giga to go fight it I thought I could take it on and that it would be an easy fight so I run there with my hoard behind me and the battle started I dealt significant damage on my spino at the beginning but all of a sudden 2 of my rexes just died I was shocked I continued to fight and my weaker Spino fell shortly I saw how low my higher spino was so I stepped out of battle to regain stamina but when I went off she rushed into battle and got killed. That made me board my Rex and I finished the fight My Rex had only 2000 hp left and my Giga had 7000 left I was sad that I had lost Spina colada and the other Dino’s
