Could be from Gundam, or from any Mecha franchise. For me from Gundam, I think Barbatos is my favorite, I love the sleek animalistic look. But overall, I love the Armored Core mechs, I think my favorite design style is what that series hits with a cross between human looking and machine designs. I also love the artwork for Lancer, I think a lot of mech designs in that game are really evocative, and I really want to get a game going if I can get my more fantasy oriented friends to play something other than dnd5e, lol. Also, special shoutout to any mech with wings
Hope you enjoy! There’s nothing else quite like it imo. I’d love for a reboot/sequel/spiritual successor someday.
