Slaughtersaurus is an unlockable extremely hard difficulty Battle Opponent. It was released in April 2013 as part of the Cash Shop Monthly Challengers series, and matches the extinct theme of the April 2013 Collection.[1]
Slaughtersaurus can be unlocked by using the Maimed Research Notes, a Cash Shop item available for 250 CSC. As of 2022, the Maimed Research Notes return to the Cash Shop each April for the duration of the month.[2] This summoning item also doubles as a Book; reading it to a Pet will not unlock the challenger. Once unlocked, Slaughtersaurus can be permanently found in the cash shop challenger tab in the Battle Coliseum.
