Danna Por is the daughter of Tom Por, Will Shane's old partner in SlugTerra. She is looking for her dad's share of Will Shane's treasure. She first appears in "Inheritance" where she sneaks into the Shane's Gang's hideout looking for Will Shane's Treasure. She is found out by their Slugs and the Gang starts to blast Slugs at her. Which she seems to be invulnerable to. She than says that she is the daughter of Will Shane's former partner Tom Por. Tom Por found out that Will Shane was working with the Shadow Clan, and a duel occurs between them, which Tom lost to, and vanished. Tom was promised a share of Will Shane's treasure, which Danna hopes to claim for herself. She then flees. She overhears the Gang talking about going into a lava cavern to gain a Forgesmelter Slug in order to open Will Shane's Treasure Chest. She captures one Forgesmelter, and scares the others with a Frostcrawler.
She then uses the Forgesmelter to open the chest, which, to her and the Gang's shock, was filled with supposedly useless items. She puts on the Shadow Talker which shows her that the Shadow clan were coming, and also makes her fall unconiscience. Kord picks her up and attempt to leave the cavern. Danna wakes up and uses her Arachnet to swing herself away from the Shadow Clan and the Shane Gang. In the end it is revealed she took a Shadow Clan Tech Sphere called the Shadow Walker that allows her to walk through the shadows just like the Shadow clan. She mostly uses Arachnets to swing around and get places. The only Slugs seen in her blasters are one Tormato, one Lariat, one Frostcrawler (to scare away forgesmelters), one Speedstinger, and the the rest are Arachnet Slugs.
- The way she walks on walls and shoots Arachnet Slugs from her wrist to get around resembles Spiderman.
