To understand Transformers fiction, it is important to understand that it exists to sell toys. Hasbro and Takara Tomy are toy companies, and they are primarily interested in continuing to sell toys to children and, yes, even "adults". The cartoons, comic books, etc., mostly exist to make this happen. To be sure, they normally make a profit in their own right, but this is regarded as mere gravy.
The "to sell toys" effect often distorts the fiction in interesting ways. Primarily, since you can't usually sell someone the same toy twice, HasTak constantly introduces new toys, and often requires the creators of the fiction to introduce the new characters into ongoing storylines. Older characters (whose toys are no longer being sold) are shoved aside to make room.
Optimus Prime: The humans should not have to pay for our mistakes...
Mike: ...just our overpriced action figures!

Ass: HYPNOSNOT, I CHOOSE YOU!
Crock: Why did you pick that particular Hokéycon to battle with?! Because it can absorb high damage?
Ass: Because the last quarterly report showed an 18% dip in Hypnosnot sales! Luckily, our viewers are sheep! A little TV exposure should boost earnings back up!
"Buy all our playsets and toys!"
— Cheat Commandos theme song
The Nerd: We know what the real message is...
Both: BUY OUR FUCKING PRODUCTS!
"New toy not stop Hulk!"
—Hulk regarding Iron Man's new armor: Iron Man, "Hulk Busters"
"Daisy-head burgers and Daisy-head drinks,
Daisy-head stockings, and Daisy-head sinks,
Daisy head buttons and Daisy head bows,
Mayzie was famous,
The star of her shows."
—Daisy Head Mayzie by Dr. Seuss
Calvin: Look at the dopey clay tiger Hobbes made.
Calvin's Mom: Gee Calvin, I think this is good.
Calvin: You LIKE it?? Where's the marketabiity?
Calvin's Mom: Ask Hobbes if we can put it on the coffee table.
Calvin: But look what I made! A hundred shrunken heads of popular cartoon characters!
Calvin's Mom: Eww, you stitched their mouths shut?!
Calvin: Gloat now, 'cause some day I'll be a lot richer than you.
Hobbes: I call it "Symphony in Orange, No. 1".
Calvin's Dad: Our lives are filled with machines designed to reduce work and increase leisure. We have more leisure than any man has ever had. And what do we do with this leisure? Educate ourselves? Take up new interests? Explore? Invent? Create?
Calvin: Dad, I can't hear this commercial.
-Calvin is thrown outside.-
Calvin: If it were up to my dad, leisure would be as bad as work.
Calvin's Dad: How can you stand these cartoons? They're just half-hour commercials for toys. And when they're not boring, they're preachy. And these characters don't even MOVE. They just stand around blinking! What kind of cartoon is THAT?
Calvin: Meet my dad, the Gene Siskel of Saturday morning TV.
Calvin's Dad: Watching a Christmas special?
Calvin's Dad: Another show extolling love and peace interrupted every seven minutes by commercials extolling greed and waste. I hate to think what you're learning from this.
Calvin: I'm learning I need my own TV so I can watch someplace else.
Jason: Honestly, what do you think of my strip?
Peter: Well, it's not particularly funny...
Peter: And it's not particularly well-drawn...
Peter: In fact, it's probably the lamest thing I've ever seen.
Jason: But will it sell T-shirts?
Peter: My, but you do have pure motives...
Do you think the world is ready for cartoon-shaped Ty-D-Bol tablets?
