I am the Eggman, (Ooh)

They are the Eggmen, (Ooh)

I am the Orbeetle!

I thought Orbeetle made for the perfect pokemon to represent Dr. Ivo Robotnik aka the Infamous Doctor Eggman. Orbeetle doesn't have much to do with Eggs themself aside from Ladybugs laying eggs, (although I guess all pokemon lay eggs) But the colors felt just right and is on point thematically.
Aside from being a based on a Ladybug, Orbeetle's evolution line progresses from being a Nerd who becomes an Inventor, who turns into a Mad Scientist bent on manipulating the will of others for World Domination!
Also Ladybugs are Beetles
Orbeetle is from the Galar Region which is based on the UK
and The BEATLES are a British Band who came up with the song "I am the Walrus" as see above which uses the lines:
"I am the eggman, (Ooh)
They are the eggmen, (Ooh)
I am the walrus"

Also one of the first of Eggmans robots that you encounter in the very first Sonic game is the Moto Bug who's design is also based on a Ladybug!
