LEGO and its products get so much of this it's not funny:
None of the characters in BIONICLE are "Bionicles". Word Of God says it means "biological chronicle" (whatever that's supposed to mean), and you can count the times it is used in-story on one hand (generally as a piece of Magi Babble, "the way of the Bionicle" or some such). Unfortunately, even LEGO fell into this trap on occasion; for example, the last wave of toys included pieces of gold-colored armor for one character to wear, which the packaging advertised as "Collect the Golden Bionicle!" *facepalm*
Then there's the term "Legos", which under pretty much any circumstance will hit the Fandom Berserk Button. The name of the company that makes the toys is "The LEGO Group" ("LEGO" being a contraction of the Danish phrase leg godt, which means "play well"). Their famous childrens' construction toy products are "LEGO bricks". The only time they themselves use the singular term "LEGO" is when referring to the corporation or its business, so using "Legos" actually implies multiples of the corporation, not their bricks; also, it's a very grating-sounding word. The company does not like this trope, with a strong insistence on their products being correctly named. The fandom, for the most part, is in strong agreeance.
Those little figurines that come in LEGO sets? They are called "minifigures", or are abbreviated to "minifigs". They are not "Legos" either.
