If your character knows the future.... · 3:15pm Feb 14th, 2016
Don't give them any other powers.
Seriously, there are many fantasy/sci-fi books out there where the character's foreknowledge is their ONLY superpower. They could be a little old lady and even Galactus would give them respect.
Why?
Because foreknowledge.... even sporatic foreknowledge is extremely powerful.
Examples:
You could place a bet on exactly when Celestia will finish raising the sun.... during the summer sun festival that Nightmare Moon returns. Most ponies would bet times like 7:00:30, 7:01, 7:02 or 7:01:30... etc. While you would be like 7:30.
Chrysalis....you could stop the entire invasion or invest in stocks in companies that make military supplies before hand and then sell them when they go up in value afterwords.
If you knew about the fight in Apploosa. You could go there with a wagon full of flour, sugar, and a lard substitute to sell to the ponies after the fight. Since many ponies would be low in the ingredients for pie. (You wouldn't be able to gouge them, but you probably would earn a bit of profit.)
You could bring a camera to the Gala and secretly take pictures to sell to the paparazii afterwords.
etc. etc. etc.
If you know even sporadic future events .... you can easily become extremely rich and influential. With enough planning, you could change events however you liked. Hell, you could easily start a cult dedicated to following you if you knew the future.
Why did I bring all this up?
Because I just read a fan-fiction where the protagonist has magic on the level of Discord and has foreknowledge. 
<Sarcasm> Oh, my character is virtually omnipotent! He/she needs a boost of power..... I know lets give him/her foresight! We wouldn't want my omnipotent character to experience any surprises. I need him/her to be halfway omniscient as well!</Sarcasm>
Foreknowledge isn't a minor superpower! Stop giving it to otherwise extremely powerful OCs!
Welp, I suppose that happened... Seriously, fore-knowledge is actually more of a geas; you end up knowing all the surprises! Life would get boring! The only time that would be a good thing is when you either just got the power, were an emotionless-already-depressed robot, or in a bad fanfic.
