Hasbro Has Unintentionally Destroyed My Personal OC...

So many of you have seen the new episode "the times they are a changeling" and it's quirky changeling guest star "Thorax" while I find it exciting that a villainous character has gotten a return front the past I am disappointed not in his portrayal but because his existence has caused the destruction of my own personal OC (my ponysona so to speak)

His name is Thorax, he was a changeling drone who often takes the form of a unicorn named Type Font he was my OC both sides of it. However because of this episode and the emergence of this new Thorax I can no longer use the name "Thorax" because I would be violating their copyright even though I came up with the name first this more then unfair and most people have said I should just change the name but I can't it's the name that made him who he was and the inky option I have now is erase him fully.

I know it seems stupid and sentimental but thorax was born from a very personal part of me and having to just give that up and change that is like having to change my own name cause I can't use it anymore.
