Mr.ByeBye

if a green boss bar appears on the top of your screen that’s labelled “Mr.ByeBye” then watch out! a green alien that runs at light speed will instantly kill you. even in full protection 4 netherite! the only damage it takes is direct player attack. you can get a pistol with the crafting recipe (shown in video) or if you kill mr.byebye he will drop it. you can get the sword with the recipe (shown in video). next, you can tame copper golems which will automatically kill mr.byebye for you, but make sure you have a shield just in case. and thats ever thing! also, here is the video link, mr.byebye mod!
