Does anyone have any ideas for unusual powers or powers never used something different from the usual (super strength, speed,flying) would be really helpful thanks
I do not, but can direct you to http://tvtropes.org/pmwiki/pmwiki.php/Main/StockSuperpowers. It has a long list of common superpowers that you may not have encountered.
There is a whole fanbased wiki dedicated mainly to superpowers. http://powerlisting.wikia.com/wiki/Superpower_Wiki if people thought of it, you might find it there. If people didnt think of it, it is not there, and we can't help you there either if you are looking for things no one has created yet as they are not yet created. Also, superpower mega chart that I got from pinterest: http://www.bitrebels.com/wp-content/uploads/2011/04/Superpowers-Mega-Chart-Infographic-Design-1.jpg
Also, have a look around blogs and websites dedicated to the history of superhero comics. There have been some really weird ones over time, some of which are remembered fondly and others which make people groan and wonder how anyone could ever have thought that was a good idea. And then there's....erm....this guy: this guy: https://en.wikipedia.org/wiki/Doctor_Hormone
