The current version of Doomerang
Robot statistics correct as of its most recent competition
Doomerang is a heavyweight melty-brain spinner entered by Team Ignition into /r/BattleBots: Hammerfall. Armed with low wedged weapon arms and an intimidating look, it immediately struck chords throughout the other competitors, which eventually led up to a pre-season grudge match with Crazy Lobster. Doomerang handily won this match by knockout.
Doomerang was placed into Group H in the round-robin qualifiers alongside Parasite, Jean Baudrillard and Omni-Bus. It quickly defeated Jean Baudrillard by knockout, but lost a similar knockout to Parasite and a close controversial judge's decision to Omni-Bus, meaning it did not qualify for the single-elimination finals. However, it was voted into the finals as one of the wild-card entrants, and defeated the destructive Doomsday in an upset before losing once again to Parasite.
Doomerang was rebuilt for the second /r/BattleBots competition, Pressure Drop, changing its look heavily and replacing the four double-wedged arms with three arms with pointed ends. Before competing in Pressure Drop, however, it was entered into The Monsterworks' tournament Extinction, where it met with decent success, eventually finishing 3-2. Unfortunately, it was kept out of the playoffs by a tiebreaker.
Doomerang 2 was placed into Group B of Pressure Drop alongside Hellhound, Channel One, Scarab, Powerdrive and Popo's Corkscrew. Doomerang 2 sadly underperformed greatly in this group, losing hard matches to Hellhound and Popo while also being defeated by Scarab in an upset. However, for the second time it was voted into the finals as a wildcard where it was handily defeated by Exertion in the first round of the playoff bracket.
Doomerang underwent another redesign for its next event, Robot Fight Night. Its number of wheels increased from three to nine, with three wheels mounted at the end of each arm, and a new weapon shape. Doomerang lost early in the group stages to Hati & Skoll, but rebounded to reach the playoffs where it defeated Tongue of the Fatman in the semifinals. In the grand final, it met Hati & Skoll for a second time, but this time was able to clinch the victory to earn Team Ignition's first heavyweight title.
Doomerang would return, relatively unchanged, for ROBOTS 3, due to changes in the rules regarding melty-brains. Despite early doubts that it would be able to perform well, Doomerang did incredibly well in the group stages, ending with a 4-2 record and reaching the playoffs for the fourth time in its career. However, it came up against the brutal undercutter Blackburn Kangaroo in the quarter-finals where it lost in a decisive knockout.
