Tropers / Cydrius

Cydrius is a french-canadian troper of Montreal, as well as a Brony. Having accumulated knowledge of many more or less obscure details, he tends to swoop in and answer questions asked on pages, correct inaccuracies, but rarely add examples, as most of those he notices are already pointed out.

In a Five-Man Band, he's either The Hero (if at the center), or The Smart Guy.
