Boom Bot

Boom Bot is a stereo-themed Attack Bot. This Attack Bot infiltrated the Corinth City Shields, with Tenaya 7 & the Grinders, by creating Sonic Interference. It is speaker-themed. They were stopped and held up by the Corinth City Forces, but Tenaya 7 quickly took them out, allowing the bot & the Grinders to continue. Similar to the monsters Somnibot and Dischordia, he uses sound as his main power, even wielding a microphone as a weapon.

When they arrived in the city, the evil forces started attacking the citizens of Corinth. The City Patrol tried to stop them, but they weren't strong enough. Scott, Flynn, Ziggy & Dillon soon arrived and took the Grinders out. They then Morphed and were ready to battle the Boom Bot. However, the robot used his Sonic Bombardment Cannons to keep the Rangers down.

Luckily the Yellow Ranger showed up and battled the Boom Bot. Yellow Ranger was able to use her Energy Blast to weaken the beast. This gave the team enough time to form their cannons and blast the bot.

But the battle wasn't over just yet. Venjix made the Boom Bot grow, forcing the Rangers to form the High Octane Megazord. The Megazord alone wasn't strong enough to take on the Boom Bot. The Black Ranger then joined in the fight with his Zord. By combining the Black Ranger's Zord with the High Octane Megazord, the Rangers gained the fire power they needed to destroy the Boom Bot.

The Rangers & Doctor K later discovered that the Boom Bot was not the primary threat to the city. Boom Bot had been implanted with a self-destruct device, that was activated during the battle. The Boom Bot was then in fact just a decoy to keep the Rangers busy while Tenaya 7 went to steal the Landsdown Diamond.
