And, according to Thomas, he is looking forward to the challenge that lies ahead. He said: "It's a massive honour to be given the opportunity to lead the club.
"It's not something I really thought about but I was never going to turn down such an honour. When Dean asked me I was over the moon."
Thomas, who has won 67 caps for Wales, joined Warriors this summer after spending a decade with Ospreys. And he believes his experience will help him with his new role.
He continued: "I've experienced quite a bit over the years in regional and international rugby and been through a lot.
"One of the things I was aware of before I joined the club and one of the things Dean spoke about when I first met him was that it's a clean slate for everyone.
"Dean has come in and he wanted to create a really good environment. When you're trying to create something special like we are at Warriors it's about everyone playing their part and trying to create a positive environment for the team. And I will look to pass on my experience within that.
"Something I've always expected from captains I've played under is for him to lead by example on the field. I think that's the most important thing.
"So as long as I play to the best of my ability on the field and lead by example then I'm sure that's half the battle."
