Khan's Ultimate will throw Terminus away. If he has Shatterfall he can stop the momentum. He needs cc reduction 70% to do this. Instead be near a ledge before you grab him then aim diagonally down offstage to guarantee Terminus dies.
If you are at low health, using commander's grab on terminus is a really bad idea. Because Terminus is a large character, he doesnt go over Khan's head after the throw so he gets a free hit and gets closer to Khan which is what you do not want.

Seriously BK has a hitbox of a truck and koga deals WAY too much damage up close. And if he uses his ultimate against (and ONLY) you. Thats ez clap for you
Many BK players go close and personal with fernando since they think they can blow him up ( ͡° ͜ʖ ͡°). While that is true, fernando has a weapon that is great for pressure. And a pressured BK will go bonkas. Maybe even blow himself up( ͡° ͜ʖ ͡°)
