Psh, fatalities were overrated.. Babalities and Friendships is where it's at!

Brutalities and Animalities are where its at plus three fatalities per character. I loved the stage fatality when you uppercutted your defeated opponent off the stage to either be impaled by spikes or fall into acid or hit by a train.

 I don't remember those.. what game was that from?  I'm only familiar with the first three I believe, watched friends of mine play it a lot when it was new.  I kinda always liked street fighter better, myself.

Mortal Kombat 3 had them.  Some of the animalities were pretty awesome to watch.
