Reiko - keep his MK4 moveset, add a couple of Kahn's hammer attacks and spiritual Kahn's helmet to his winning pose. I will not go with shoulder charge since we already have several characters who use it.

Frost - while Sub-Zero use ice for freeze his victims, Frost can use it for everything else. Her moveset will be like this: ice nugget (Sub-Zero's move from MKvsDC), ice spikes (ice spike appear from the ground sending victim into air), ice/snow boulder throw - just like characters could do in MK4, ground ice (Sub-Zero's classic move). Fatality - frozen kiss - Frost kiss her victim, freezing him/her into the process, enemy falls back and shatters upon contact with the floor. The story is, since Sub-Zero is dead for now, she will fight against Sektor over control of Lin Kuei.

Drahmin - look at posts at page 2.

Taven - give him more time control powers: slowing down - Taven sends a projectile towards the opponent and if it contacts it will slow down opponent's speed for a little time, enhanced version will freeze him in place. flying time/eternity time - Taven will decrease/increase round time for 10 seconds. Time bombs - Taven will throw a bomb that looks like sand glass. Also his speed of light special from MKA is good enough to make a return but with slow mo effects behind it, instead of fire.

+ Tanya, Shinnok, Quan Chi, Fujin, Mavado, Kenshi, Havik...Khameleon

I love the ideas you have for taven moves so he wont be just another character with fire and hopefully the firegod could be playable one day maybe you should make a idea for his brother deagon
