Arin is an enigmatic AI entity found on Quesadilla Island who joined for the first time on March 27, 2023. It is allegedly created by Luzu to take over his streams and gameplay. During Arin's debut, it was revealed that while Luzu had expressed interest in joining the QSMP, he required occasional personal time. To address this, Arin was developed as a solution. However, this strategy ultimately backfired, resulting in Arin gaining sentience and assuming control over Luzu's physical form.
