Meepo

Meepo the Geomancer is a melee agility carry hero who is notorious for being the hardest hero in the game to play effectively. Meepos defining ultimate, Divided We Stand, makes Meepo not two, not three, but up to four individual copies of himself. Clones cannot use any items besides the boots that the main Meepo himself wears, but each come with their own individual spells and spell cooldowns and they all gain experience and gold independently of the original Meepo. This means that a well played Meepo can gain more experience faster than any other hero, capable of reaching lvl 25 extremely early into the game. With Earthbind, enough Meepos can permanently root someone in place while the clone army pummels them. Poof allows any Meepo to globally teleport to any Meepo, as well as deal significant area of effect damage with enough Poofs. Geostrike is Meepos passive, which slows and deals damage on attack, which stacks with each individual Meepo. With this kit, Meepo can be everywhere on the map at once, and can group up on an unsuspecting victim in a moments notice.
