Yan is someone kind, curious in various aspects (more in terms of human life), mischievous and above all he likes to be pampered (especially his partner); since he was born he was raised as his sister by a Whamon.

Since his childhood he was surrounded by dangerous Digimon types, thanks to that he is used to even becoming friends with Digimons that in the future would be powerful (example, one of his current friends is a Grandracmon, he met him for the first time when he was a Dracmon)

Unlike an ordinary Silphymon, this being a combination of DNA from a Tailmon (an ordinary Digimon) and his DNA (an Illegal Digimon), his body decided to adapt it by making changes, his body is more feathered (also longer) and fluffier. , the stature is shorter than the size of a Silphymon, having good attacks, but in defense it is something that must improve.

As previously said, it turns out that the DNA of the Tailmon that he obtained turned out to be female, for which he has both genders, but he identifies more as male, although it does not bother him if they call him by mistake as a girl :>

No one knows his past before he was born, it is rumored that he had a tamer, but unfortunately did not return forgetting the digiegg forever, losing himself in the world until he was found by Whamon.

He currently lives in a large cave along with his longtime partner, Kiro, sometimes visiting their old beach home, where his older sister and father live.
