Monster Madness and when it is over
It is rumored when Monster Madness ends in a few weeks/months (Although date is unknown still) that Korath will be available to everybody. It is still unknown though. This will also include his abilities. You will just have to wait and find out.
Now that more informtion is known Korath most likely is going to come back. According to Ikk200 (Thx for the info) he will come back but not as easy as you get him right away). You might have a more difficult or similar challenge than the Monster Madness event but no 100% truth of it. You might find information in the BYM forums but still almost 100% sure Korath will come back but not sure if it will be another challenge.
Please comment of what you think/know about it and thanks for making this wiki page reach over 67 comments. I am just an average BYM user and only a level a 38. Bye
