(House of X#1 - BTS) - When Charles Xavier and Magneto established the sovereign mutant island nation of Krakoa, Xavier delivered a telepathic message to the world, welcoming every mutant to live on Krakoa. Sonos Rex was one of the many mutants who accepted.

(House of X#1) - Sonos Rex, Fauna, Wrench and seven other mutants met with senior X-Men Banshee and Jean Grey at the former Xavier's Institute for Higher Learning, now renamed the Graymalkin Habitat. Outfitted in standard X-Men costumes the mutants followed Banshee and Jean through a Krakoan gate granting them access to the new mutant island nation. The new arrivals were welcomed by Wolverine and Charles Xavier.

(X-Men VI#10) - Sonos Rex and a friend witnessed Rogue fly by at supersonic speed when she rushed to save the lives of Wolverine (Laura Kinney) and Lady Deathstrike on Phobos.

Comments: Created by Jonathan Hickman and Pepe Larraz.

Sonos Rex codename implies that next to his reptilian or dinosaur-like exteriors as some form of sound abilities.

Robert's last name implies that's he's of Welsh descent. Wynn and its variant Wynne are derived from the north Wales and Shropshire form (with initial mutation) of south Wales Gwyn(n), Gwynne.

Sonos Rex is one of the many new mutants introduced in the Krakoan age, but one of the few who's been identified. Others include Abeni, Curse, Fauna, Fish, Kayla and Wrench all of whom are getting a profile.
