A few days a go my friend was fighting his favorite Elder Dragon:The Kushala Daora. While he was fighting he was at the place where the tigrex lands in the main scene you first meet him. The Kushala Daora did a glide attack at him as he dodged and the Kushala Daora just stayed there in flight and after that there were two of them who moved at the exact same time. After that they attacked again and the gliding attack doubled the damage. After that they faced at each other then did the glide attack and became one more.
