The ARMS North American Open August 2020 was an official online ARMS tournament held from August 8th, 2020 to August 9th, 2020 by Nintendo of America. The bracket was organized by a team of Battlefy staff alongside the help of Era (a prominent online TO for the ARMS scene). The event was first revealed on July 27th, 2020 as part of the NintendoVS summer series of events. First place received download codes for Super Smash Bros. Ultimate, Splatoon 2 and the Super Smash Bros. Ultimate Fighters Pass Vol. 2 while second, third and fourth place received 2500 My Nintendo Gold Points (equivalent to $25 USD). Unlike the ARMS North American Online Open (April 2020), Nintendo of America hosted an official stream for this event on their Youtube, Twitch and Twitter accounts featuring CONEY, EE and Jordan Kent on commentary. Mileve and HanukkahJamboree also provided unofficial streams for pools. The tournament received 767 players, making it the 2nd biggest event in ARMS history behind the ARMS North American Online Open (April 2020) which featured 880 players. The tournament ended with AstroNinja0 finishing in 1st place, Para finishing in 2nd place and Asqew finishing in 3rd place.
Due to the large number of entrants, the player pool was divided up into 4 brackets which were named after various characters in ARMS. These characters included Spring Man, Ribbon Girl, Min Min and Max Brass.
