The Puppet Theatre

This rivalry involves a user named Shenron Weasley, as well as the entire Geometry Dash Wiki Off Topic Board.

For whatever reason, users Brown Eevee and Shenron Weasley repeatedly engaged in flame wars in various threads, often throwing insults. Shenron's primary account profile listed Eevee as "the source of the darkness that has occurred time and time again throughout Geometry Dash history", and also insulted user 404 found, stating that he "tends to spend most of his time generally loafing around".

At some point, Shenron also decided to start using sockpuppet accounts, such as Heatran Rudania Ultima Weapon, Cala Marity Ganon, Ignotus Pervrell.exe, The Last Laserdisc Dragon Priest, Fireblight Heckylpoo XI, Unnamedblockster661 and TheMajesticZam accounts, to try to pretend he was a different user. Others quickly saw through the disguises, allowing the rivalry to continue.

Eventually, after several bans, Shenron decided to stop using most of his sockpuppet accounts and stick with the UnnamedBlockster661 account, using that as his main account. It would take a bit longer for the insults and general disrespect to stop, but those eventually came to an end as well.
