Colossus (Colossal) Fury

Fury activates when the colossus is at max mana but he keeps using "gather magic" for 10 more seconds. It takes all his mana and prevents him from regaining it in exchange for giving him the power to unleash ultimate destruction.
It has to be a bonus... a nice bonus.
We already got ideas about the Infernal and Stygian colossus:
Infernal creates like 5 volcanos in a circle around him. They spit out fireballs that fall on people's heads and turn into mini infernals.
Stygian kills everyone around him and turns them into zombies.
Your turn to post ideas!

Ice = frozen people and buildings and or damaged with blizzards.
Flesh = :?
crystal = major crystal shard aura?

Flesh:
Releases his smell to all people around him, slowly killing them all to their end.

maybe this is something?

Maybe... The abomination's disease. But he does it in a very large area since it doesn't kill and its power has to be equal to the stygian's.

Also, silent, can you explain a bit more?

They will have a few seconds after their Fury is ready to land it better.
This gives you guys more possibilities for suggestions of Furies so please let me know what you come up with.

with Furies, you mean like Ultimate attacks?

Yep, like in arcade fighting games ya know... street fighter and the likes...
