The user can create and fling chains from their arms. Just before launching a chain, the user can choose a substance that the chain will home in on and stick to — it will pass harmlessly through all other substances. If they don’t pick any substance, it will just stick to the first thing it hits. The user can retract any chain they have out, pulling it (and anything it’s attached to) towards them. If the object or person that the chain is attached to is strong enough to counter the pulling power of the chain, the user will instead be dragged to the thing that the chain’s stuck to.
