Don't know if it can be useful but I found this. I couldn't copy the link but it sends me to the page in the second image.

Hoo boy some people in the comments should really show him some respect. To Bruce in that specific point in time? Probably not, but yk, even a rock is a better father than Brian. To other people in need in the Immortal Hulk timespan? Absolutely. Everyone is getting in line (me, I'm getting in line)

Sorry for taking so long. I searched again on pinterest and found a signature on a Marvel Disk Wars fanart (which I have a lot more of) and if it's them it's mittonox on twitter. I dunno if they locked their account or something else 'cause the tweets are protected but you could try reaching out.

Kind of reminds me of this fanart here, also considering it's about agents of smash AND in japanese. I think I found it on pinterest but sadly no signature. If you want I can go check later if I can find something in the comments of the post.
