Ace Lightning: Since Mark is in trouble for destroying the appliances (caused by Ace powering up from them) and not allowing Ace to power up from them anymore, Ace is caught between a rock and a hard place when he's low on power and being stalked by Anvil. Mark gets him to an old observatory which contains a transformer that Ace uses to return to full strength and defeat Anvil. He makes the observatory his home, calling it Thunder Tower.
