Trueno

Trueno is the firstborn in the Gold Pack.

Appearance
Trueno, due to a 2.5 glitch, is a mostly brown and black male wolf. However, he is shown as white with a faint bit of orange over one eye in "How to Fix Pup Colors!" where it is shown how to fix the colors for your wolf pups.

Personality
Trueno attempted to explore behind the den, unlike his littermates, however, once he was trained he preferred to lay around and beg for food when it came. When his siblings tackled him, he normally stayed beneath them and whined, not doing anything about it for a few moments before getting them off. During the journey to the Summer Hunting Grounds, Trueno laid down lazily and waited for his parents to carry him.

Thunder
Trueno and Thunder got along well. Thunder usually fed Trueno first, even when he wasn't as hungry as the other pups, and was usually carried by Thunder when traveling to the Summer Hunting Grounds. When a hawk carried Trueno away, Thunder was shocked but didn't take the time to properly grieve until reaching the Hunting Grounds.

Silver
Trueno was always quick to beg Silver for food, and Silver was always quick to deliver it. However, beyond being a source of food and his mother, Trueno and Silver never became close. Silver wasn't there when Trueno died, as she was off hunting, but she came back to see Thunder staring after him.

Storm
Storm and Trueno were never close, but Storm often ended up trying to butt Trueno away from Thunder and Silver when food came.

Plata
Plata often took advantage of Trueno's slight laziness and tackled him regularly, annoying him but not prompting him to tackle back.

Gold
Gold was Trueno's closest sibling. Gold and Trueno normally stuck by each other, and Trueno was seen following Gold away from the den when they were still being trained.

Death
Trueno was carried away and killed by a hawk when Thunder had to save Gold from drowning in the river. Trueno was park of the Spirits of the Sky Pack.
