DISCLAIMER: IF YOU ARE ON ANY OTHER PLATFORM BESIDES OLD MOBILE IGNORE THIS TIP.
On old mobile these things are neutral to all tames, meaning that if you try to lure a giga to a rando's base to be evil and they have all their tames set to passive, then that's not gonna do anything unless you manually aggro the giga then tank each hit with your tame and the dude's tames in the giga's hitbox until something dies.
This also means that you can easily trap a giga by using a medium sized mount, equipping 4 metal dino gates in your hotbar, then go up to the giga and quickly place the gates when it stops moving. There exists a video somewhere on the ark mobile discord of me doing this with a pachy.
This also applies to rexes
However if you try this on any other platform including ark use you and your tame will almost certainly die as unlike old mobile wild gigas WILL always be aggressive to all tames.
