Blackarachnia: Why do you always talk to yourself? Megatron: I simply have a penchant for intelligent conversation.
The Predacons set-up an ambush at Tarantulas' lair for the two approaching Maximals. Upon Scorponok warning of their near arrival, Waspinator, Inferno and Terrorsaur immediately open fire at the entrance.
Megatron: Cease your fire, you fools! Wait for a target!
Failed hostage negotiation:
Dinobot:(holding up Tarantulas) Do not fire, Megatron! I have a hostage! Megatron: Why so you do. (Megatron immediately blasts Tarantulas to scrap)
Every and any time Waspinator is blown up(which is all the time, by the way). Even in the most hilarant ways:
Rattrap vs. Waspinator in Other Voices, Part 1. Rattrap reminds Waspinator that they have a ceasefire. Waspinator agrees and points out that he's not using any weapons and proceeds to punch Rattrap. Rattrap decides to remind him that he's one of the dirtiest fighters of the Beast Wars, and kicks him in the gearbox, robonoogies him so hard that it produces sparks, then kicks him in Waspinators big... FAT... STRIPEY...
Optimus:*stares*note Optimus piloted a trans-warp bomb into the second alien moon, destroying it before it could destroy the planet. But he couldn't escape the pod, so he blew up with it. Then he got better.
Rhinox: "Okay, stupid question."
In "Changing of the Guard", Rattrap is tasked with salvaging the AI from their sunken original base in a mini-sub. Not only do we have Cheetor imagining himself playing with it like a cat toy, there's the bit where Rattrap is enjoying being a sub-captain, complete with a jaunty sea tune playing in the background, then we cut to Silverbolt staring at his communicator as the music still plays.
In that same episode, Rattrap's submarine gets jolted around several rocks, accompanied by pinball noises, and when it finally comes to a rest, both of Rattrap's eyes are flashing "TILT".
"Dark Voyage", where Rhinox, Rattrap, Dinobot, and Cheetor are blinded, and Rhinox is the only one calm when Cheetor is being squeezed to death by a giant snake.
Megatron: Inferno, aid Quickstrike. Inferno: As you command, my Queen. (walks off) Dinobot: I was not aware you had given yourself a new title.
In "Other Visits, Part 1," after monitoring Tarantulas operating on his own, Megatron attempts to contact him and is ignored.
Megatron: Again that spider defies me! Inferno: Say the word, my Queen, and he shall burn. Megatron: Not just yet... and for the last time, stop calling me that! Inferno: As you command, my Qu— (Megatron strangles Inferno one-handed)
"Gorilla Warfare" has Optimus and Dinobot doing a biological survey, and they discover a weird plant. Apparently, this plant can not only hear, but get offended, since it spits a barbed seed right where Dinobots arms can't reach it, leading to this:
Dinobot: Get this thing off of me! I can't reach it! (freaked out) GET IT OFF!!!
(Optimus removes the pod and drops it, where it blooms into a new plant)
Optimus: That's how it spreads it's seed. See, we've learned something.
Dinobot:Yeess. From now on I shoot my dinner salad before I eat it.
The fact that a) It didn't occur to Dinobot that he could just transform and knock it off and b) it actually becomes a Chekhov's Gun later, just makes it funnier.
In "Law of the Jungle," Waspinator remains oddly insistent on waiting for the proper signal before attacking Maximals (or, alternatively, decides to troll Terrorsaur):
Terrorsaur: Do something! Waspinator:(sing-song tone) Terrorsaur has not given signal~. Terrorsaur: ATTACK, YOU IMBECILE! Waspinator:(calmly) Waspinator will engage enemy.
In "Victory," the Predacons are hiding out in very close quarters, and it's clearly starting to get on their nerves:
Terrorsaur: Stop slobbering on me, Tarantulas! Tarantulas: I am feasting! Waspinator: Give Waspinator more room! Tarantulas fat enough already! Tarantulas: If Waspinator does not stop cuddling me like a stuffed toy when he sleeps, I'll eat him as well! Waspinator: I'd like to see you try! Tarantulas: Yes, I will! Waspinator: No, you won't! Tarantulas: I will so! Terrorsaur: You all make me sick! I can't stand this any longer, Megatron! I've gotta get out! (Terrorsaur hops around and cackles crazily until Scorponok casually punches him)
In "A Better Mousetrap" Rattrap does his exercise routine to get through a booby-trapped hallway ("Feel the burn!") and when he rounds the corner he waves at the security camera and by extension, the audience!
From "Other Victories," Megatron puts Quickstrike on trial for betraying him. Not only do we get to see Megatron wearing a judge's wig, but we get to see Waspinator, as Quickstrike's defense attorney, say that he is perfectly fine with his client being executed. See it here.
The season 1 episode "Dark Designs" has Megatron capturing Rhinox and turning him to evil. He's not Brainwashed and Crazy so much as Brainwashed With an A in Evil. Having Rhinox on their side becomes more of a detriment than a bonus, as he proceeds to thrash his way through the Predacons. His Deadpan Snarker mannerisms combined with an almost murderous degree of Chronic Backstabbing Disorder give way to some fun exchanges, mostly at the Predacons' expense. For instance:
After Rhinox squishes Scorponok under a pile of crates, Megatron and Waspinator later discover Scorponok underneath next to a ruined console (both sabotaged by Rhinox), and Megatron pokes at his inert form with his tail-blade like a child with a stick.
Megatron: Idiot! What have you done? Waspinator: Hmm...Idiot does not respond! Idiot is comatose!
Afterwards, Rhinox plasters Waspinator with another crate, leading to Waspinator believing he's the Insecticon Shrapnel, right down to picking up Shrapnel's Verbal Tic and forgetting his own. Blackarachnia's opinion on the matter only encourages Waspinator's bizarre antics.
Blackarachia: He's wacko. Waspinator: Wacko? NO! Wonko! Wonko the Sane! ** Blink and you miss it, but Waspinator actually cops a feel on Blackarachnia.
Megatron FacePalms, Waspinator waves to the audience then starts punching himself in the head, and then both Megatron and Blackarachia stare bemusedly at whatever Waspinator was waving at.*
And yet again, when Megatron turns around to find another couple of his minions have been incapacitated, he finally throws his hands up in frustration.
In "Coming of the Fuzors Part 2." Megatron barks his orders to his team of Predacons to destroy the Maximals, asking (rhetoricall) if there are any questions. When Quickstrike answers, he barely gets a word out before he is grabbed by the throat by Megatron who impatiently asks what the question is. Quickstrike asks if they have to be quick in disposing of the Maximals, and if he can't make them suffer a bit before finishing them off. Amused, Megatron releases Quickstrike, stating that he likes him but that business comes before pleasure.
Dinobot's funeral speeches.
In "A Better Mouse Trap" when the maximals believe Rattrap was destroyed by Sentinal, and they each say a few words about him.
Dinobot: I won't disgrace his memory with lies. He was a stinking omnivorous pestilence! Still in some perverse way I will miss him.
In "Fallen Comrades" when Optimus is shot down.
Dinobot: Fear not Optimus, I will ensure your funeral is a glorious one as befits a warrior who died in battle!
Optimus: Afraid I'll have to miss it Dinobot, I'm not scrap yet.
Dinobot: Hmm are you certain? It would be a triumphant passage.
"Power Surge": Being this series's version of The Starscream (next to Tarantulas), Terrorsaur manages to enact a very rare and unprecedented Curbstomp Battle on Megatron after tapping a giant natural formation of Energon. Megatron is summarily blown to bits. At the end of the episode, this Energon nest egg has been blown up by Rattrap and the Predacons have ultimately refused Terrorsaur's leadership in favor of restoring Megatron. Terrorsaur comes back to the Darksyde thinking he'll still be in charge, only for the single worst karmic rebuttal to occur from a fully repaired and very pissed off Megatron:
Megatron: Well, well, well... Look.. who's.. BACK.(gives him a scorching Death Glare)
