Gumpi is a 34cm tall gnome, weighs around 6-7kg and has insanely messy brown hair. He wears a leather heat 3 times too big for his head and a bandolier holding brass cartridges over his torso, and baggy cloth pants held up by his nearly fully tightened belt.
He wields a relatively massive revolver that mainly fires eldritch blasts, and sometimes other blasts. He also has a tiny ring that molded to his tiny finger size that he can go inside of.
Gumpi was brought up in the City Of Brass where his parents still live, Gumpi wasn't really good at much other than stealing things and starting fights, but when Gumpi stole his revolver from a prestigious arms shop and his ring from the Fire Sultan a huge fire genie and the king of the City of Brass him self's quarters.
He was hunted down by the Sultan's soldiers, when he found the Biglibots pirate crew mostly made up of Gnomes, and escaped with them. He officially became their fourth crewmember at first just looking for an escape but over time he became really good friends with the other three crew members Kwimf the captain, Fimple the druid (also his closest friend) and Ringo the walking suit of armour.
In his travels the Biglibots crew picked up nine more crew members (all Gnomes), but while going to explore a new planet they'd found they crash landed on an planet not too far away and all got spilt up.
