Rikimaru the Stealth Assassin is a hero from Dota Allstars. He is an Agility Sentinel hero.
Born as the heir to the satyr dominion, Rikimaru was trained by the mightiest warriors of his race. However, the power of the Burning Legion managed to corrupt many of his kind, leaving them as mindless beasts in the forest. Vowing revenge against the Scourge, he sharpened his skills for battle. Using his small size to his advantage, he can render himself invisible, enabling him to stab his enemies in the back. And by using thick smoke as cover he becomes nearly untouchable.
