Anytime Divatox interacts with the other female villains. It's usually Astronema, but she and Rita share some amusing zingers in the season opener.
Divatox: How wonderful to see you... Frita.
Rita: It's RITA. So, still after the Power Rangers?
Divatox: Who? Oh, them. Really, Frita. You MUST get out of the dumpster more often. I've DESTROYED the Power Rangers! Well someone had to.
Then later, when Dark Specter is deciding who will be the one to go after Andros, the two actually get into a physical squabble, fighting for who will be the one to do it, Divatox throwing in a Continuity Nod / Lampshade Hanging of Dark Specter's resemblance to Maligore.
In "True Blue to the Rescue," Divatox calls Astronema asking her (in the most condescending fashion) to be on the look out for Storm Blaster and let her know if she sees it, and Divatox will send 'an army or two' after it. At one point, Astonema makes a 'blabbermouth' gesture to Ecliptor. Then she declares that she'll capture Storm Blaster herself and Divatox gets into a huff and begins mocking Astronema, leading Astronema to hang up on her. Evil Is Petty indeed.
Cassie teasing Ashley about her reaction to seeing Andros unmorphed.
In the team-up with the Teenage Mutant Ninja Turtles, after Astronema has mind-controlled the Turtles and made them take over the Megaship, they come across a glowing cloud. Astronema asks what it is.
Michelangelo: You're asking a turtle who lives in a sewer to explain a cosmic event?
Raphael kicking Elgar out of the way. For those who were pissed off that he was the one who blew up the Power Chamber, seeing him just get knocked aside was very satisfying.
When Andros and Zhane go to try and find Karone, there's this brief exchange:
Andros: You dated my sister?
Zhane: I didn't know she was your sister, but I should've.
(Quantrons approach, but Zhane and Andros manage to hide in time)
When Elgar calls Astronema the smartest boss he's ever had over a phone, Divatox then grabs the phone away from her to berate him. Elgar then hides behind a console and pretends to be an operator with the Veemonvoice.
Anytime that the Rangers are on Earth and not on a mission tends to produce plenty of hilarious moments due to Andros's unfamiliarity with human customs leading to things such as him attempting to eat a banana without peeling it first.
After the Rangers have defeated the Psycho Rangers in "The Enemy Within," Zhane sneaks up on Andros in a Psycho Red costume, pretty much solely for shits and giggles.
At the beginning of the episode "Survival of the Silver" when the Rangers are surrounded by the aliens. It's all in Andros' tone:
Andros: You think they're friendly?
Andros: I didn't think so either.
It's the 'I know the answer to this, but I have to ask anyway' resignation in his voice that gets this troper every time.
Divatox muttering to herself about her demotion from lead villain status in "The Delta Discovery."
Divatox: Why don't I get any of the good gigs anymore?
The Hilarious Outtakes are this by definition, but it's all the more funny whenever Melody Perkins (Astronema) breaks character, because of the sheer Mood Whiplash. The blooper reel of "A Date with Danger" stands out, as it's all about her (except for one scene with Patricia Ja Lee messing up her line).
T.j's And andros's dialouge after the latter jumps on Mega V 5 (A Rocket) with Mega V 1(A Astronaut)
T.J: "H-Hey! Watch the paint job! What'd you think I am? A taxi?!"
