Ren 10 001.jpg

Ren Tennyson is the main protagonist of Ren 10:Equinox. He is Ben Tennyson's adopted brother and is the wielder of the Eonotrix.


Ren is sometimes a wise guy,as quoted by Gwen. He comes up with jokes and puns while battling, and gives nicknames to villians(Ex.Sunder-Mullethead). He is cocky at times, but knows when to be serious. He quotes he will stop at nothing to protect the ones he loves.


Ren's signature style is a black T-shirt under a blue jacket with the Omnitrix symbol where Ben's 10 is. He wears black pants and blue Converse shoes. There is also a special feature inside his jacket,eyes,shoes,and Eonotrix where if he turns into Beastazoid(a soon-to-be featured Eonotrix alien),the mentioned objects turn orange because Beastazoid is enraged by the color blue.
