Instrument Of Destruction
- The hallways shown in Adam's encounter with the mystery pianist and the Cogs had never been shown as a part of Angel Grove High, and they wouldn't appear again after this episode; they appeared to look more like an actual high school than the Angel Grove High set.
- After finishing his classical music, the cloaked Skull emerged from the door on the southern end of the west wall of the main hall; this was the first time this door was shown in use.
- Mondo turned the piano at Angel Grove High into Fortissimodo, but while the music room piano was brown, Fortissimodo was black.
- Repeatedly throughout the episode, the monster was referred to both as Fortissimodo and Fortissimono.
- Skull should've easily been able to see Adam morph.
- In both the US and sentai footage, morphed Adam used boxing moves, but Adam wouldn't take boxing lessons until Challenges.
- Symphony Hall's appearance changed during the switch from American footage to Sentai.
- After being told by Zordon that Adam had reported that Fortissimodo wouldn't rest until he had captured the mysterious pianist, who was currently watching the fight from the bushes, Tommy said there was no time to lose, and that they had to get to the Zeo Jet Cycles.
- After Fortissimodo had grown and was threatening Adam, the Rangers continued fighting Cogs on the ground rather than summoning their Zords.
- After morphed Tommy had used the Defender Wheel to free morphed Adam from the grasp of giant Fortissimodo, Adam simply followed Tommy around as Tommy fought off all the Cogs around them.
- Morphed Adam spoke into the wrong wrist when he used his communicator to tell the others they needed the Zeozords.
- Tommy told Adam that he and the others had better get in their Zords and that he'd catch up soon, but it appeared that the others were already in their Zords when Adam teleported into Zeozord Four.
- When destroyed, Fortissimodo's hat flew off, and landed on a nearby building, where it remained for the duration of the shot.
