Security personnel were on high alert at MegaCon in Orlando due to concerns surrounding the popular Minecraft YouTuber, Dream. A fan reported a gumball cosplayer causing issues, prompting security to be notified. The head of security warned attendees against disruptive behavior before Dream's presentation. The cosplayer was likely referencing Nicolas Cantu, who has a complicated history with Dream, including a confrontation where Cantu made threatening remarks. Dream has faced harassment and safety concerns but his panel proceeded without interruptions, showcasing innovative technology for Minecraft, despite some technical glitches.
