Leobreaker tries thinking of a way to get to Gigantion, and Snarl preforms a Face Fault.
Leobreacker: ...Or a really big slingshot?
Snarl: (falls over) Will you get serious?!
Jetfire's afraid of needles!
So Megatron has just been beaten, fair and square, and his rage has everyone scared since he has taken hits before. When they're unable to understand why this beatdown at the hands of Metroplex was so rage-inducing, Soundwave drops this golden line!
It really loses something in writing. Cybertron Soundwave talks in a monotone and with extra special effects on his speech, per usual, but he's played more like a DJ (to the point of actually being voiced by one.) The line would be mildly amusing from anyone, but from DJ Soundwave, it's enough that you'll probably be changing your shorts after.
The bots from the Giant planet are good for a laugh.
Sideways is a total Butt Monkey in the episodes "Escape" and "City". First he gets beat-up and embarrassed by some human kids in Escape, then he acts all grumpy in City and has a whole bunch of paint cans fall on his head!
Sideways: Oui, mon Capitaine!
I love episode 42, When Lori and Scourge are reunited after their meeting on Jungle planet. Lori tells Scourge just how disappointed she is in him. "Scourge got told off by his little sister! Scourge got told off by his little sister!"
Time to attend the "Bud's School of Painless Leadership"!
To make this a bit funnier, SCOURGE is also taking that class.
On a franchise-scale, meta, Fridge Brilliance scale, the concept of the Unicron Singularity itself. Turning your Biggest Bad into an all-consuming blackhole that actually affects the continuity of every single Transformers series ever has to rank up amongst the best and most amusing of all handwaves and lampshades ever.
