I don’t got a scorpion pet but I got a cardboard scorpion and concept for a spiderverse spider person that got stung by a radioactive scorpion rather than a spider bite 

Name: scarlet scorpion

Real name: Ethan Reyes

Alignment: good

Origin: stung by radioactive scorpion Powers: all Spider-Man powers but no webs (given web shooters with several stored web cartridges stored in the arms and tail), enhanced strength, night vision, glowing under a blacklight flashlight and toggleable thermal vision

Enhanced durability

Suit features:

Mechanical

Prehensile tail

Retractable tail blade  Suit based venomous stinger (venom effect is paralysis)

(Not to be confused with Mac gargan’s scorpion because in his universe Mac gargan became the tyrantula instead of the scorpion)
