If you're familiar with the anime Evangelion and if you are good at making mods please read this.I always wanted to have large mechs in minecraft which you could use .You can make the mechs(from the show) each part(cooling systems,the pilot plug though requires hard to obtain materials (diamonds,obsidian,iron blocks,etc.). Giant mobs are destroying your land you can use the mechs to slay the giant mobs. The plug suits can also be made(but in different parts according to the armor slots) with the three colors white,blue, and red. Plug Suits are made with leather,lapis(to make it blue), redstone(to make it red), or white wool(to make it white). As in the Anime if the mech takes damage you feel the pain so in the game if the mech takes damage you'll take some damage as well.
I hope someone can do this. Plus I'm sorry if I'm being being too demanding.
