I like the idea of having stretchy powers, similar to Mr. Fantastic. My thoughts are that it would work as a Blaster/Corruptor primary & Defender secondary. It would be 'melee' from a distance. It might look silly, and probably isn't super likely to happen due to the weird stretching effects, but it could be neat.
In a similar vein, I thought telekinetic melee would work something like this. 'Melee' attacks, but from a distance.
