All the RayEvil’s were built / ‘owned’ by a different Rayman villain throughout the franchise. Some overlay, yes, but mostly it’s diverse

Most of the times their creators would leave 'brands' on them to know who belongs to who

They were all created to oppose Rayman or someone else once in their life

RayEvil’s aren’t entirely natural Thingamajigs. They were all artificially made for whatever their creator desired. These normally consist of a Blue Lum and whatever else they have (most commonly Dark Magic)

Now some individual facts about the characters!!

Raymesis:

Created by Mr. Dark, stolen by Ales Mansay at a young 'age'

Hates Mansay and wants to go back to being Mr. Dark's creation (Mansay claims that he created Raymesis)

Became an 'older brother' figure to Shadow after Mansay dumped the two in a room together

Super snappy, angry, and extremely petty. Thinks he's Rayman's true rival but Rayman couldn't give a shit

Created the Antis (Him, Glombrox, First King, and Selena) as a way to get back at Rayman

Shadow Ray:

Created by a Blue Lum and copious amounts of Dark Magic. This made them extremely unstable and (if they could feel it) in lots of pain

Ales Mansay's favorite creation. Thinks that they're the most 'sucessful'

Half-blind and only really cackles / giggles. Needs glasses to sorta see

Can't fully move. They need to 'mark' someone and follow their 'trail' to even go anywhere

Fascinated with art and film. Loves a good movie and is easily amused

Shadi (Bad Rayman)

Also created by Mr. Dark but left for dead in the Livid Dead after his defeat

Did not understand free will until she met Goth Teensy. He helped her find her own personality and being

Very disliked in the Livid Dead with the other Nightmares. She looked too much like Rayman for them

Can pick things up super easily by just watching

Still friends with Goth but became distant after he because the Livid Dead Door guard

RayX

Created by Razorbeard; he was left in the Glade after the Robo Pirates fled the Glade

Made to tire Rayman out and keep him occupied. Very much destined for sports and high-energy activities

Very competitive and will do anything to win. He will cheat, cry, and fight to get what he wants

Cannot handle loosing. He will throw a fit and get extremely violent

One of the only RayEvil's without a Blue Lum. He is pure machinery and alien technology

Showbiz

Mansay's first RayEvil. He created him, but he was sold to Rigatoni. Gave him a hatred for Mansay

Athletic, can breathe / control fire, and can detect his limbs. Everything Rigitoni wants in a star

He's very snobbish and under the impression he's more popular than Rayman (He also has never left the circus)

Even as a performer, still has his old programming. If he see Rayman or anything similar, he will get needlessly violent

Extremle 'one man show' and hates working with others
