Most unlike Henry VIII — king, cross, bumping off queen (5)

I believe the answer is:

rangy

I'm a little stuck... Click here to teach me more about this clue!

'most unlike henry viii' is the definition.
(rangy can mean thin - Henry VIII was famously fat)

I don't understand the rest of the clue.

Can you help me to learn more?

(Other definitions for rangy that I've seen before include "with gangly limbs" , "Having members at length" , "Long-legged" , "Gangling" , "Antipodean mountain" .)

I've seen this clue in The Times.
