I'll make the profiles in a moment, but here's the ideas I had for reference and early judgment.

The first is angel, a young man who has to help his single mom raise his brothers and sisters.  His a very kind soul who puts others over himself, his overly nice though to a fault, and doesn't know how to fight so that is a issue that will require fixing.

The other is a character based on the blob of the brotherhood only made a good guy.  A young English boy who was once skinny as a rail but becomes fat with the ability to become fatter and bigger.  The bigger he is the more durable, stronger, ands unmovable he is, but at the cost of speed and mobility.  His very shy and timid but does enjoy getting big and strong.
