Challenger Creation Concepts

In DOTA, they are known as Heroes, In League they are known as Champions but in this book I called them as Challengers. Some characters herein are based on those above-mentioned games, some are inspired from other games like Flash Games, some are inspired or based on Webnovels, Comics, Real Life, or H-Doujins. Some are a 80% carbon copy from the original, but some are my own ideas.
