Andrew displays the powers of an electricity wielding Elemental. However, unlike others, he has spent the majority of his life on the run. As such, his physical prowess and offensive abilities are weak. On the other hand, those abilities which have allowed him to survived are much more developed.
'Elemental' isn't a subclass of mutant or other super. It's an entire species of its own (at least it was in the old RPs. any thoughts, O?)
All Elementals had the following characteristics:
-control of a single element (earth, fire, water, electricity, etc).
-superhuman physical capabilities.
-can fly/teleport short distances/both.
-can adapt and disguise themselves as a member of any human culture, including language.
-can sense other super powered beings and distinguish them from humans.
Now, by the standard of his people, Andrew is weak, because instead of being taught and trained by his people, he is running from them. By human standards, on the other hand. his physical abilities are still super-human. To top it off, those racial abilities that have allowed him to escape and hide (such as teleportation, language adaptation and 6th sense) are far more improved.
Make sense?
