For me, Pixelmon crashes all the time when I enter an arena or pick up berries, for example.
here is my crashlog:

if you need more of the crashlog then say it
On the one hand: the crashlog is actually too little, but on the other hand I found the full one here: https://www.minecraftforge.net/forum/topic/86854-pixelmon-1122-crashing-ticking-player/?tab=comments#comment-407578
The thing is this: The minecraftforge.net forum is not intended for Pixelmon and other problems (only for the future.).
To your problem: Your version of Pixelmon requires Forge 2838, while you have 2529. So here either the latest Forge version or play it safe and download the 2838 at the end: http://files.minecraftforge.net/....12.2.html
After that, it should work.
