Arishem Question?

I'm not really into marvel, just never been my thing, my boyfriend got me playing rivals and it didn't really change much, but then he got me to play the card game, Marvel Snap. It's fun, but the question I have is about the character Arishem, not the card.

He looks really cool, and have been hyper focused on him since I've seen him, he's just so aesthetically cool.

for the actual question,

Are there like specific things I can find out about him, like is he in specific comics, I mean obviously he is but what? is there like lesser known stuff about him? I'm just very curious about this specific uh robot celestial being dude.

hopefully didn't blab too much, bad habit, anything would be appreciated, recommendations for comics with him or even like....a poster or something would be cool.
