Yes, stealing Genzoman's art and putting it on a t-shirt and giving him no credit would surely be awesome.
Still, Nintendo would never allow for that much blood and violence in a Zelda game. well... not the blood anyway~
Wait, GENZOMAN did that?! Yeesh. Didn't think he was that violent. Also not quite sure how making it a one-off T-shirt design and re-purposing it for a macro are terribly different
Just gotta act chill as you do it, it's like killing a cajun lightning bug -squish- then adjust your suit and nothing happened.
