The battling robots are coming back. ABC has picked up a second season of BattleBots, the epic robot fighting tournament that was revived by the network in 2015.

The summer reality series, from Whalerock Industries and Ed Roski and Greg Munson, creators of the original abclogoBattleBots franchise, ranked No. 1 in its time period in total viewers (5.4 million) and adults 18-49 (1.7/5), as well as across all key male demos in its first season. BattleBots improved its hour year-to-year by double-digit percentages with total viewers (10%), adults 18-49 (31%), men 18-34 (63%), men 18-49 (73%) and men 25-54 (69%). In addition, the series was Sunday’s top-rated broadcast show of the summer with kids 2-11, according to ABC and Nielsen stats.

The second season again will see robots waging battle in a single-elimination tournament until a champion is crowned. Next season, the tournament will double in size and feature an expanded field to include expert roboticists, garage builders, families on a mission and past winners returning to defend their turf, ABC says.

Lloyd Braun, Chris Cowan, Ed Roski, Greg Munson and Aaron Catling executive produce. MGM Television will distribute the program internationally.
