Ben 10 True Omniverse Message Reaction by Iscuseri
I should've done this months ago, but it's my fault for forgetting. This is my earnest reaction to Power Master's Ben 10 True Omniverse Message, which announced the series' (now temporary) cancellation. The 2nd chapter covers additional topics that I couldn't cover in the 1st one, and a 4th one is about Power Master un-cancelling True Omniverse. Rated T for some coarse language
