Tanks are durable, front-line champions that help lock down enemies and start fights. They're usually found leading the charge, choosing the right times and situations to initiate aggression. Many tanks can also protect their more fragile teammates by stunning or pushing around dangerous foes and limiting their damage potential. In mobile legends most classes of heroes are really versatile in terms of abilities and with the item crafting variations a "tank" can be played as a dps if you choose the right equipment. Usually, tanks are laning on the bottom tower.
There are currently 9 Tanks in the game.
