The Next Tier of Hero

So as it is going its been a line of Hero troops going from barbarian to archer, so now it would be logical to move to the giant, So this hero would be very slow but would take a bunch of damage and deal it back as well. So here is my idea! A hint of warning is that most of these will be estimates and in ranges for i am not good for finding perfect balance so try to bear with it if you dont mind.

Name of Hero: The Colossus
Buying Cost: Somewhere between 40k to 70k DE
Damage per second: Would be Stronger then the rest of the Heroes in strength
Hit Points: Same with the the HP
Movement Speed: Would Move at a very slow speed atleast slower then giants and golems.
Description: Its "monument" Would be called Giants Cave which would be the cave where this monster lives, When the creature is summoned into the battle it looks like a giant but on a much larger scale giving it the size if 2-3 giants were stacked on top, He would move at his slow pace but end of demolishing everything in its path till it is eventually stopped.
Ability: The ability i believe it should be a Roar or Shout of some kind and would have the effect of a freeze spell in a Area of Effect around the Hero, So it would slow enemy troops and defenses. When being upgraded it results in more range long lasting or effectivness.
Leveling: As shown in the past i am not good with ballance so in basic terms leveling would increase these things as they level up.
