Season 1, Part 1, Disc 4, Episodes 22-26.

22 - Vow
Megatron tries to take on the Autobots again, this time with the Star Saber and 7 Minicons.
Intro - Wreckage, Knockout, Dualor, Buzzsaw, Backtrack, Oval
Errors/confusion/notes:
-The Decepticons have been busy collecting heaps of Minicons 'offscreen', with 6 shown at the start of the episode that haven't been seen yet.
-Optimus can't understand the Minicon language in this episode, but Hotshot does.
-The constant fat/food jokes for Fred are a bit much.
-They try to explain the Minicons being loyal to Megatron as 'looking up to him as a father figure'. Huh? They fear him. Why don't they just try to escape?
-Megatron retreats leaving behind 7 Minicons (the six 'new' ones and Bonecrusher).

Minicon count:
Autobots (21) - Highwire, Sureshot, Grindor, Jolt, Longarm, Sparkplug, Liftor, Spiral, Rollbar, (unknown), Incinerator, Mirage, Downshift, Dirtboss, Bonecrusher, Wreckage, Knockout, Dualor, Buzzsaw, Backtrack, Oval.
Decepticons (10) - Leader-1, Crumplezone, Blackout, Swindle, Drillbit, Rook, Crosswise, Jetstorm, Runway, Sonar.

23 - Rebellion
Sideways tricks Starscream and Megatron into fighting each other, to help make the Decepticons a tighter fighting machine as the Autobots start getting the upper hand in the war.
Intro - none
Errors/confusion/notes:
-Sideways is reporting into someone, far off in the galaxy.
-Sideways mentions the Astroblaster (is really the Requiem Blaster), as if the Autobots already have it, but none of the Minicon team have been found yet.
-The war is 10 million years old according to Starscream. The 'millions of years' war concept never made sense, with all the destruction and casualties they cause in just a few days.
-Cyclonus snores as well, as if he needs to breath. And flys in helicoptor mode on the moon again (no air, so shouldn't work).

Minicon count:
Autobots (21) - Highwire, Sureshot, Grindor, Jolt, Longarm, Sparkplug, Liftor, Spiral, Rollbar, (unknown), Incinerator, Mirage, Downshift, Dirtboss, Bonecrusher, Wreckage, Knockout, Dualor, Buzzsaw, Backtrack, Oval.
Decepticons (10) - Leader-1, Crumplezone, Blackout, Swindle, Drillbit, Rook, Crosswise, Jetstorm, Runway, Sonar.

24 - Chase
The 3 kids and Street Action Team are sucked into 'Cyberspace' (an alternate dimension) by Sideways, on behalf of his true master.
Intro - (none)
Errors/confusion/notes:
-Laserbeak appears to be a mere drone who loses power when the Autobot's computer is destroyed.
-Laserbeak is stepped on by Megatron, but is later okay.
-Sideways calls the alternate dimension 'Cyberspace', which Alexis calls the Internet. This is such a '90s' perception of the internet being a 'world' or place where all the info is stored. The 'world' is a shared illusion, generated by an unknown force.
-The sneak peek silhoutes are always fun to try to work out when they are thrown into episodes like this. One appears to be Tidalwave, while another jet shows up that doesn't look familiar.
-Sureshock is repeatedly called Grindor by everyone.
-We get our first look at Unicron in Planet Mode.

Minicon count:
Autobots (21) - Highwire, Sureshot, Grindor, Jolt, Longarm, Sparkplug, Liftor, Spiral, Rollbar, (unknown), Incinerator, Mirage, Downshift, Dirtboss, Bonecrusher, Wreckage, Knockout, Dualor, Buzzsaw, Backtrack, Oval.
Decepticons (10) - Leader-1, Crumplezone, Blackout, Swindle, Drillbit, Rook, Crosswise, Jetstorm, Runway, Sonar.

25 - Tactician
Thrust and Jetfire arrive, which further intensifies the conflict.
Intro - Jetfire, Thrust, Inferno, Terradive, Thunderwing, Gunbarrel, Fetch, (at least 4 other Minicons), (generic? Minicon)
Errors/confusion/notes:
-Heaps more Minicons are revealed to be in the possession of the Decepticons (I could count 10 - Terradive, Thunderwing, Gunbarrel, Fetch, Inferno, Sonar, and 4 others), suggesting that the 'Minicon Hunt' plot concept could be mostly over now, and the rest of the series deals with the Unicron plot concept.
-Thrust mentions that the Minicons in that room have been there for years, but could be a translation error.
-If the Decepticons had so many Minicons, including the 7 that they lost in episode 22, they should have been plugging them all in, 3 or 4 each, and blitzing the Autobots. They are mere tools and weapons, so why didn't the Decepticons use them while they had them, instead of being defeated on level playing terms.
-The room also contains Sonar (animation error), who is currently on Earth with the Decepticons in the next scene.
-Thrust appears to be able to be invisible.
-Megatron welcomes Thrust to Earth, but they are on the Moon.
-Thrust is said to be undefeated, but is easily defeated by the Autobots in his first couple of encounters.
-The Minicon the Autobots retrieve and release is unrecognisable, and could just be a generic Minicon as it is not named or seen again.
-Thrust recommends to Megatron that Starscream is loyal and should be his second in command.
-Demolishor was/is considered second in command, and doesn't like Starscream being 'promoted' above him.
-Thrust convinces Megatron to let him use the Star Saber, but then never uses it.
-Megatron trusts Thrust, but should know that no Decepticon can be trusted.
-Thrust is also using the Air Military Minicon Team (the triple changer jets).
-Scavenger asks Optimus for strategy when in trouble, but should be taking charge as a battle master.
-Animation error has Optimus reversing from Megatron with his trailer between shots without it.
-Jetfire arrives 'just in time'.
-Air Military Team crash to the ground, and the Decepticons retreat, but somehow they manage to be back with the Decepticons later.

Minicon count:
Autobots (22) - Highwire, Sureshot, Grindor, Jolt, Longarm, Sparkplug, Liftor, Spiral, Rollbar, (unknown), Incinerator, Mirage, Downshift, Dirtboss, Bonecrusher, Wreckage, Knockout, Dualor, Buzzsaw, Backtrack, Oval, (generic? Minicon).
Decepticons (19) - Leader-1, Crumplezone, Blackout, Swindle, Drillbit, Rook, Crosswise, Jetstorm, Runway, Sonar, Inferno, Terradive, Thunderwing, Gunbarrel, Fetch, (at least 4 others).

26 - Link Up
Thrust sets up another trap to defeat the Autobots, but Jetfire is once again instrumental in saving the day.
Intro - (Jet Convoy)
Errors/confusion/notes:
-Optimus is said to be requiring extensive repairs from the battle in the last episode, but didn't appear to be injured in that episode. I think the original script (before translation) probably had the 'repair' process being an *upgrade* instead, to prepare him for his powerlinking to Jetfire and give him the ability to fly (which he does now).
-Kids are introduced to Jetfire, but talk as if they already knew of him (probably stories from the other Autobots).
-Hotshot is said to be too young to have been in any of the wars on Cybertron. Probably a translation error, because the 2-part episode 'Past' contradicts that.
-Jetfire is just as cocky and reckless as Hotshot, which makes it odd that he is second in command.
-Liftor is called Longarm, yet again, by Smokescreen.
-The Air Military Team is called Air Defence Team by Thrust.
-As mentioned above, Optimus can now fly.
-Optimus combines with Jetfire to form 'Jet Convoy'. Odd that they used the Japanese 'Convoy' name, instead of something like 'Jet Prime' or 'Jet Optimus'.
-No one else knew of their combining ability, even those who have fought with him for millions of years, suggesting that it is something he was just upgraded to do, but the Western Translation made out he was just being repaired instead.
-Animation error has the chest of Jet Convoy coloured red like Super Optimus, and with a Decepticon Symbol on the chest, when he has defeated Megatron.
-Animation error has Jet Convoy flying over to the Autobots after the battle, but landing as Super Optimus.

Minicon count:
Autobots (22) - Highwire, Sureshot, Grindor, Jolt, Longarm, Sparkplug, Liftor, Spiral, Rollbar, (unknown), Incinerator, Mirage, Downshift, Dirtboss, Bonecrusher, Wreckage, Knockout, Dualor, Buzzsaw, Backtrack, Oval, (generic? Minicon).
Decepticons (19) - Leader-1, Crumplezone, Blackout, Swindle, Drillbit, Rook, Crosswise, Jetstorm, Runway, Sonar, Inferno, Terradive, Thunderwing, Gunbarrel, Fetch, (at least 4 others).
