The final episode of the season was on tonight, and I just finished watching it. This was definitely a fun season to watch, with quite a lot of unexpected outcomes. If you haven't seen it yet, then I would highly recommend checking it out.
I think I should mention that, thanks to the recently introduced streaming service "Discovery+" (only $5 per month), it's now possible to watch every episode of the past five seasons of BattleBots whenever you want. In addition, there's a special new BattleBots series available exclusively on Discovery+, called "Bounty Hunters", which is basically a series of mini tournaments where lesser bots compete for a chance to face off against one of the more popular and/or destructive bots, and if they can triumph over all of that, they win a small cash prize.
I don't yet have Discovery+, but I certainly intend to get it sometime soon, and once I do, I will definitely be checking out the BattleBots Bounty Hunters episodes.
