It’s probably supposed to be “Death Reborn Revolution”

The Japanese is:  デス・リボーン・レボリューション 

“Desu Riboon Reboryuushon” 

In general Japanese spelling conventions, uually the long “o” in Riboon is derived from the English word “Reborn” while “ リボン “ribon” with a short o is used for Ribbon. 

Cyprine and Ptilol, in the very same arc have an attack that uses this short “o”  called “リボン・バスター” (ribon basutaa). So we know “ribon” and “riboon” are probably two different things. With Cyprine’s attack, the use of ribbons is an essential part of the attack while in Saturn’s attack, it’s not necessarily as important and seems to be there more for stylistic purposes. So we have stronger reason to believe it’s Cyprine who has the “ribbon” and Saturn who has the “reborn”, “Reborn” doesn’t quite fit Cyprine’s attack very well.

Additionally Naoko gives us a set of Japanese characters to help Japanese readers understand what is meant by Saturn’s move, these characters appear for some attacks with the purpose of assisting Japanese readers who might not be familiar with the English-derived words. These are not necessarily literal…

For example: Dead Scream is given “ 破滅喘鳴 “ (literally, Destruction Stridor), it’s not identical, but the gist is the same thing.

For Death ??? Revolution it’s: 死世界変革 literally “Death World Revolution”.

From this, we can get a clear sense of being “reborn”, any reformation of death is likely to have an aspect of rebirth.

However, there is no indication at all of any words that could connect well to “ribbon”.

I hope that answers your question
