Never start talking to me about Marvel comics. The sheer amount of useless information my brain holds about Marvel comics is astounding.
Like... did you know Psylocke from the X-men is Captain Britain's sister? She used to be a white lady who dyed her hair purple and she had cybernetic purple eyes because she lost her real ones and she was super-famous as a model and was a psychic mutant and was even Captain Britain herself for a while (in a really ugly costume). Then she got body-swapped by... gangsters... into the body of... an asian assassin lady called Kwannon, so now she's Asian, but she... is still psychic? (which makes no sense because mutant powers are attached to your DNA, not your soul...) and her old body, the white lady with bionic eyes, got the soul of the assassin and became a villain called Revanche.
So the important takeaway here is whenever they give Psylocke an American accent in games and stuff set in the main Marvel 616 universe continuity (ie. the universe of the comics), it's WRONG. She should sound like a posh British lady.
