Random Ramble: Lasting 010 Minutes in the Ring with Devil Doom

This has been bugging me for the longest time.


So I have been playing Shadow the Hedgehog since its release, and I have never been able to last in the Devil Doom boss fight for exactly 010 minutes.


The longest that I have ever lasted in the ring with Devil Doom is 09'58"24.


Rings are also a factor at this point, as it is near impossible to keep your ring count above 030 when the 09'30 mark passes.


My question to you folks on this is this:


Have you ever lasted the full 010 minutes in the Devil Doom boss fight;


If you have, what exactly happens?


I would like to finally bring this mystery to a close, having already suffered enough just trying to do this for the past 06.(something) years.
