Grand Unifying Guesses/Transformers

The following are from Cybertron

 * WMG
 * NERV'S technology
 * The Cars
 * The non-human Looney Tunes characters.
 * KITT (Knight Industries Three Thousand).
 * The Iron Giant

Pretty Cure is a Transformers continuity family.
The Dark King, an ancient evil who desires total destruction of all reality, is clearly Unicron, with Gooyan being a smaller, Cybertron-esque regeneration thereof and the Nightmare Group and such being people from Planet X. Primus, who has been female all this time and has learned to create an avatar of herself (the Queen), created warriors in her image (which were cute girls this time around because of her avatar, rather than the usual giant robots) to defeat Unicron. These warriors fight using the power of light, which is the same as the power of the Matrix, and (like Cybertronians) can transform between normal-looking forms that fit in on Earth, and more attention-getting (but clearly visually related) forms that are suited for combat. The Matrix itself originally took the form of the Prism Hopish, but was later transformed into the Symphony Set.

Oh, you want proof? One of the emails posted on the Sector Seven ARG mentioned the Garden of Light.

All of the following scientists were contracted by Sector Seven at one time or another to study Megatron and the Allspark:

 * Drs. Walter Bishop and William Bell
 * Dr. Isaac Kleiner
 * Gendo Ikari--meaning that Evas are reversed-enginered decepticons!
 * Tony Stark
 * Reed Richards ...but nothing much came out of that.
 * Dr. Henry Pym, who went on to build Ultron.
 * Miles Dyson
 * Dr. Katsuhito Stingray
 * Dr. Hell
 * Dr. Catherine Halsey
 * Doctor John Smith, in the 70s... or was it the 80s?
 * Both.
 * Doctor Light and Doctor Wily
 * Dr Leo and Liger Shishioh
 * Doctor Emmet Brown
 * Baxter Stockman and Professor Jordan Perry
 * Dr. Insano
 * Dr. William Magnus, who used his findings to reverse-engineer his own team of sentient robots.
 * Doctor Noonien Soong. Which means Lore is a Decepticon.
 * Dr.Weird, and boy did they regret that choice.
