I think people who you play online with should be able to do multiple tag team fatalities against other tag team fighters. Like if I use scropion and Zub-zero against Ermac and Noob-saibot they could team up and do fatalities against the other tag team.

That would be cool.Another tag team fatality would be Ermac and Kenshi.

Kenshi or Ermac would use their telekinese power to lift their opponent in the air.Then,the other uses his telepowers to rip the opponent apart.For a winning pose, they can hover in the air and do flips,then land.
