Mission 6: Combine! Go-Buster Oh

'''Combine! Go-Buster Oh''' (合体！ゴーバスターオー Gattai! Gōbasutāō?) is the sixth episode of Tokumei Sentai Go-Busters.

Summary
After failing a simulation that would combine the Go-Buster Ace with the GT-02 Gorilla and the RH-03 Rabbit for the twentieth time, Hiromu apologizes for hesitating in the formation as Ryuji suggests that maybe it is not the younger member's skills that are the issue. Later, while while wondering if he should go faster, Nick reminds Hiromu how he and Ryuji met with the latter teaching him to throw rocks across the lake. Though Nick explains that Ryuji may know the problem, Hiromu sees no need to ask for help. Suddenly, the headquarters' alarms ring as Enter, having used a fragment from the Cutterzord to find an entrance in the Ijima district, invades the Energy Management Center's headquarters with the newly created Sprayloid to make his way to Hangar 7 where Cutterzord is being held. Having the Buglers hold the Go-Busters at bay, Enter finds the Cutterzord and hacks into the EMB mainframe to reactivate the Megazord, while warning another will be coming in nine minutes. As the Go-Busters arrive, Cutterzord's projectiles seal the blast doors as Enter enters the hangar's self-destruct sequence before leaving the Go-Busters to die with a suicidal Sprayloid. However, Blue Buster throws Red Buster out of the hangar so he use the Go-Buster Ace to get his teammates out while they destroy Sprayloid. Though the summoned Sprayzord interferes with the Go-Buster Ace's attack on the hangar, Blue Buster and Yellow Buster escape in time. Having realized that he must trust his teammates as they trust him, Red Buster combines the Buster Machines to form Go-Buster Oh to deal with the Cutterzord and Sprayzord, destroying the Vaglass Megazords with the Dimension Crash attack.
