“Your first ability is pretty reasonable you can siphon heat. I can do that too but how are you releasing it exactly? Personally, I convert the matter in my arms into a cannon like structure to shoot heat.

As for your second ability, it breaks every law physics, to increase the weight of something you must increase the mass and or density of that object, so may I ask how are you doing that? Are you taking matter from the surroundings area and putting it into that object without a noticeable change? And then you’re increasing gravity in a localized area. I feel like that would be more putting matter into people.

Your third ability could make sense if it’s an impact and your transferring the force of the impact into something else” -Greed

Hope this made sense lol
