Talk:The Ending of the End - Part 2/@comment-26423071-20191114174024

Just to clarify:

the power-nullifying rock that acts as Kryptonite to Equestrians doesn't have a name, so I gave it one.

I call it tachyon cobalt.

So, while I made up the name, the rock itself exists in canon.

Also, I think it can nullify all sorts of power, not just unicorn magic or chaos magic. Back in "To Where and Back Again", it was used to subdue Spike (dragon powers), Rainbow Dash (Pegasus powers) and Pinkie Pie (her Toon-like powers).
