Tribesmen is a theme created by Wikia user Mat96 and this is my entry to his contest.
As you can see, three brave tribesmen (Including the Ant Shaman) are having to battle the immense mech and the swift drone invaders piloted by that dastardly alien. Can they stop him? Use the Shaman's staff to summon powerful ants to take down the mech or use all of your brute force and weapons to crash the drone into the mountainside! Be brave, be bold, be tribesmen! Or something. xD
