Reserves, also known as Alternates or Backups, are names given to BattleBots competitors who are accepted for an event, but only as surplus in case of any dropouts or late withdrawals.
As early seasons of BattleBots were open invitation with only the later rounds being aired on Comedy Central, there was no need for a specified number of competitors, with robots whose opponents could not compete given byes. However, with the revival of the show on ABC in 2015, there was a set total of 24 competitors with the intention for every tournament fight to be filmed, edited and televised. As such, to prevent the need for bye rounds, reserves were accepted to fill in if called upon. It was then up to the teams whether they still wanted to build for the competition with no fights guaranteed.
In recent seasons on Discovery, the field of robots changed, but the need for reserves did not. Teams were typically listed in order of priority: first alternate, second alternate, and so on. However, the order of reserves have rarely been known.
A list of alternates for each BattleBots competition can be found below. Please note that this list is not exhaustive, and is subject to change upon discovery of new information.

World Championship V[]
The 2020 season is not known to have had any alternates, largely due to the competition being postponed due to the COVID-19 pandemic. This allowed for numerous teams to build during periods of lockdown, and also forced other teams to withdraw once the new filming dates were announced.
World Championship VI[]
A total of three teams attended filming with reserve robots, two of which competed exclusively in BattleBots: Champions. Triple Crown attended as a reserve, but was later granted a single main season battle against Valkyrie. Perfect Phoenix also only competed in the side series, but was originally accepted for the 2021 season. Team Doom Robotics were forced to withdraw from the main season due to conflicting schedules with Tyler Nguyen's school at the time.

With the full Fight Night schedule being released on January 5, 2023, alternates were purposely not added.[1] Big Dill attended as a reserve, but it later entered the main competition after newcomer DOOM was forced to relinquish its place as a full competitor, whose full Fight Night schedule was instead given to Big Dill.
