Hmmm...I got quite a few, actually...
When in "Victory" Rhinox says to Tigatron: "Back in your seat!" And Tigatron says: "But..." And Rhinox scolds: "I said SIT!" That was really funny and memorable, and I'm bettin' if Tigatron had protested further, Rhinox woulda given him a SPANKING! That'd be a sight to see! XD
The part in "Other VOices, Part 2" where Airrazor punches Blackarachnia's lights out! I Loved seeing her do that. It showed how effective AR is, plus it was nice retalation for the then obviously not yet Maximal Blackarachnia's deed of shooting her down in "Spider's Game." A good ol' quid pro quo!
The part in "Equal Measures" where Cheetor chuckles: "All part of being perfect!" And looks at Dinobot, who walks out in a huff afterwards(clearly he meant to get rid of the cat, this being prior to their becoming the friends they were later)
The aforementioned part of "Victory" where Rattrap slams Dinobot in the nuts with that pole. Well, Dinobot, YOU'RE certainly not gonna have any children!
The part in "Proving Grounds" where Blackarachnia head butts Silverbolt and says: "Warned ya!" and suddenly starts to collapse and groans: "Ugh...not such a good idea..."
The part in "Cutting Edge" where the same Blackarachnia blows Waspinator outta the sky and his eyes get all big and inflated! Yeesh, imagine how embarassing it must be to have she who was once your teammate blow you clean away! And the way his eyes looked was priceless.
The part in "Deep Metal" where Depth Charge shows how rude he is with saying: "Go chase a mouse." to Cheetor, and, even funnier, "I gotta hand it to you, Primal, when you screw up, you do it big time." Man, is he obnoxious or WHAT?
Finally, I loved the parts in both "Power Surge" and "Dark Designs" as well as "Coming Of The Fuzors" where Terrorsaur, Optimus, Rhinox and Waspinator all had seperate turns at copying Megatron's "YESSSSSSSS" catchphrase. I always liked that sorta stuff.
That's that.
