==Trivia==
*He has a resemblance to the ''Beyblade: Metal Fusion'' character Ryuga, most notably their similar hair color and reptilian-like eyes. Also, the strange headband Ryuga wears looks very similar to Ren's forehead in his true form.
*Prior to being revealed as an antagonist, the official website spoiled the fact that Ren was working for Barodius.
*Ren is the only major character to be recast partway through his respective season.
**He is, however, not the only main character to be recast overall. Ace was also recast towards the end of the season. Coincidentally, Ace's second voice actor was also Ren's first voice actor.
*He is the only one of the Minor Twelve Orders to have an intermission screen that shows their real form.
*He is the earliest of the six/seven antagonists to change sides in the series, joining the Brawlers less than two-thirds of the way through the season.
*Out of the three villains to swap sides, he is the only one without a mask. Instead, he uses something to change his entire appearance.
*Ren's name could possibly be reference to the ''Ren'', a part of the soul in Egyptian mythology.
