Naldo

Naldo was one of the teenagers from Stony Stream, except from a different timeline known as "Thirteen".

Overview
In 1988, Heck and his partner Naldo stumbled upon Erin Tieng and her friends when they were chased by old-timers. He led them into the tunnels and helped protect them until they reached the ship where he promised to heal Erin from her gunshot wound. However, as soon as they got inside, they took off and left the others stranded in the forest.

Erin later woke up with Heck and Naldo scurrying about their warehouse. She found they had put iNsecs in her stomach, small electronic bugs, to heal her. The teenagers were dying due to a gas leak but told her they will help her return to her time as she reminded them of their younger selves. They took off in the time machine and returned her to the basement where they originally found the time machine as they passed away.
