The colossal Titan.
This titan can utilize explosive transformation describe as Atomic bomb, Depending to the user it can use steam emission causing high temperature winds to inflict damage to skins of the individual near the area. Colossal titan is also used for anhillated enemy nations due to it's power to create atomic bomb transformation. Just like Armin did to the naval fleet of Marlyen.
The downside is every time the user utilize explosive or steam emission it's tissue muscle/ muscle mass will decrease making only the skeletal structure remains. Which will make them vulnerable for attacks. They can't defend themselves due to their slow in nature movements.
Tell me your thought about the Colossal titan.
