When I tamed my first Giga I noticed that the meele when from 115 to 60. And dododex said it had high weight my tribe members let me keep him and I named him red moon because he was silvery-blackish top and red belly. My tribe members, Sakura, Ray, and Iron (idk how to spell irons full in game name) went kind of crazy when Ray found a wyvern egg while it was taming and someone named clown helped us trap it and ko it. I thought it was funny it had more hip than my lvl 165 twins that have 215 damage. So if your taming a Giga I recommend having a tribe or people helping you. Now my Giga sits in front of Rays tribe (my tribe but Rays the leader) base , the castle, we tamed it in Ragnarark and now it’s there
