I never fight a giga before and I have op rexes.. I just experienced how powerful he is.

I have 19 rex always ready to fight boss.with saddles 100s

Someone lured the giga close to my base so I decided to give it a try. I bring 10 rexes and my tape whistle attack they fight for like 5 minutes he killed all my op tames.. they had 37k and D600 D700.. so I grab my tek tape and kill him.. I learn my lesson plus now you guys know that u can't fight a giga with rexes.. I may give it another try with healing pigs and rexes to se how it goes..
