Alexander, known online as Technoblade, was an American YouTuber known for his Minecraft videos, livestreams, and involvement in the Dream SMP. Technoblade registered his main channel on YouTube in 2013. His videos consisted primarily of Minecraft gameplay, particularly on the minigame server Hypixel. After rising to popularity in 2019 for his performances in player versus player (PvP) events, Technoblade was invited to the Dream SMP Minecraft server in 2020, further increasing his following.

In August 2021, Technoblade announced his diagnosis with cancer. Following unsuccessful treatment attempts, Technoblade died from metastatic sarcoma in June 2022, which prompted widespread reactions across both the Minecraft and YouTube communities.
