One person lists a way to protect Teemo, and after that name a champion that wants to kill him.

I'll start, Teemo just managed to survive a teamfight with 40% hp, But Darius is chasing him down and Teemo already has 5 bleed stacks on him. Who jumps in to help?

Nobody.

I jump in to help Darius.

All of a sudden lux starts laughing dealing 500 damage then snipes both rumble and darius.

Rumble and Darius run into a Teemo mushroom minefield

talon chases low health teemo, he uses his cuthroat and ult at same time and now he is invisible ready to rake

But then Jervan jumps in and ults, teemo flashes away from ult, leaving Talon, jarvan and Darius stranded into the cataclysm.

He's helping guys

Blitzcrank flashes into the Cataclysm and pulls Teemo back to the group.

Gragas Ults everyone away from teemo
