Q: What are protogens?
A:Protogens are a regulated species based on primagen. They are more open than primagen in that anyone can create protogen characters, but they are still limited in that certain design features are not allowed. These features are disallowed as they would make them look too similar to primagen. Protogens may not be hybrids, and they must be bipedal.
Protogen are shorter than primagen and have smaller, more rounded visors. Their visors are made of very small machines which can effectively chew food which is then swallowed. Protogen have working digestive systems, unlike primagen. They are stated to be earlier prototype creatures which were eventually modified into the primagen.
Certain "rare" protogen features are allowed to be included freely. These elements include three sets of ears, multiple tails, wings, supernumerary limbs, etc. Source: Click here! [en.wikifur.com]
Q: What is a furry?
A: Someone who says they are furry is generally expressing an interest in anthropomorphic animals and/or creatures (and perhaps some affiliation to furry fandom). They may express that that interest in a variety of ways - through art and stories through to roleplay and performance. How deep or meaningful an interest in Furry is varies greatly from person to person. Source: Click here! [en.wikifur.com]
