"Ah!"
When their pursuer caught up, all three of them were halfway up the ladder, caught between top and bottom.
Since the entire platform and ladder were metal, their pursuer merely drove the twin batons in his hands into the ground, and a powerful current instantly swept over the whole platform. The three of them cried out in pain as the electricity struck them, then fell from the ladder.
