New Hero : The Hydra [ dragon like beast]

Hydra:
An land dragon who looks very very ferocious and is dark black color. His base is like a den and some bones outside. It is unlocked at TH10 [or TH11 maybe if it comes] at a hefty cost of 1,50,000 Dark Elixir. He attacks using his 3 heads by biting the target constantly and rapidly. Note he is a NOT flying Hero and not a related to Dragon. He has 40 levels too .
Upgrade from Lv 39 to Lv 40 = 4,00,000 Dark Elixir
HP : 2100 [ at lv 40 = 3500]
DPS : 252 [ at lv 40 = 412]
Speed of movement : 30
attack radius range : melee

He is very fast and tough to aim at.He can also bite aerial troops. His ability , melee range and speed balances his lack of attack. His ability is very special and original and sometimes very effective. Nothing can attack it [ no trap , Troop , hero , defense or anything ] while it is in motion . So to sum up , only when he does damage is he vulnerable. Unlike the previous heroes he does not have any special ability unlocked at LV5. He has no special target and blasts any thing in his radius. He also can be kept on guard or sleep mode
