Does any body know games similar like Dota 2?

You mean the Moba genre in general? There's plenty, just go Google MOBAs.

Heroes of newerth

DotA Allstars? There is also Legendary Heroes on the iOS.

DemiGod, League of Legends, Smite, Heroes of Newerth, DotA [original], Dota 2, Minions, Awesomnauts, Rise of Immortals, Monday Night Combat, Super MNC, Warhammer Online: Wrath of Heroes, Air-Mech, Battle for Graxia, Guardians of Middle-Earth ...
There may be more, but this is all I can think of at the moment.
Like with DotA, many of these are also available campaigns for existing RTS games.

There's Battle for Graxia.

I play demigod and find it quite fun, it doesn't have many characters but it's nice to play even in single player.

Awesomenauts is real great.

Thank you all for the suggestion. That will be it i will close the thread.
