Junkrat is a hero that excels at defending an area through the use of traps and indirect fire; he is valued for his damage output and area denial capabilities. He has strong mobility thanks to Concussion Mine and deals high (if inaccurate) damage with his Frag Launcher. The explosive and hard-to-aim nature of his weapon, however, makes it challenging for him to fight at close range with most heroes.
