New promo art for 'Avengers: Infinity War' shows a character who may be the next villain for the film.

Artwork on a mug revealing the Black Order shows what looks like a minion of Thanos.

The character isn’t part of the Black Order as we know it, so their intent is questionable.

'Avengers: Infinity War' is also said to tie together all the Marvel movie stories to date. So how will this character fit in?

The film hits theaters May 4th.
