Selkies

The Selkies are magical creatures introduced in Season 5 of Winx Club. They are known as the guardians of the portals of each planet in the Infinite Ocean and also become allies of the Winx during the battle against Tritannus and the Trix.

Why they Sucks

 * 1) To start, they're just blatant rip-offs of the Pixies, with the difference of being bigheaded mermaids instead of bigheaded fairies that were created just to match the Season 5 theme.
 * 2) The only reason they exist is just to promote toy marketing alongside the Winx dolls, playing the role of mascots for each doll just like the Pixies and Fairy Pets were in previous seasons.
 * 3) Just like the Fairy Pets in the Season 4, the Selkies were all but forgotten after the season they were introduced in and are not even mentioned again, which makes them pointless characters in the franchise.
 * 4) Their designs are extremely lazy, since all of them are practically identical, just differentiated by the color palettes and a small decoration on the shell, which makes it difficult to distinguish which is which.
 * 5) Their designs can be considered ugly, mainly due to their huge heads (which are even bigger than Pixie heads), their faces and the bad color palette for each one. Being a failed attempt to create a cute character, but it turns out to be quite uncanny.
 * 6) They are also very poorly written, with some of them not even having personality.
 * 7) *Speaking of which, Phila and Nissa were the only Selkies who didn't bond with any fairies either.
 * 8) They are terrible guardians to protect the portals of the Infinite Ocean.
 * 9) Phila can be considered annoying because she often refers to herself in the third person.

Redeeming Qualities

 * 1) The design of normal Selkies is passable, with differences in hair and skin tone.
 * 2) They don't return to appear on the show after season 5.
