Gugu Mbatha-Raw has officially made her MCU debut, as judge Renslayer in the new, Loki series.
The first episode of Loki establishes Gugu Mbatha-Raw as Judge Renslayer, someone created by the Time-Keepers to judge for the Time Variance Authority shows up and pleads with the judge to talk to Loki, and use him to help in another variant case.
The talented actress is certainly not very well known compared to her co-stars Tom Hiddleston and Owen Wilson, which is fitting as her character, Judge Renslayer is not very well know either.
While there is no certainty that Kang the Conqueror will make an appearance during Loki, there is no denying that his character is connected with Ravonna Renslayer.
