Jam on the Lam: Featuring Rag the Slave.

In a galaxy where the only thing more volatile than an asteroid strike is the ethical code of a sports executive, Benjamin Rivera (an anxious dinosaur accountant best known for number-crunching and self-deprecation) is just trying to start over. Freshly arrived on the industrial orb of Trashtar after his previous soccer team was liquidated for 429 years of tax evasion, Benjamin hopes for a quiet life.
Instead, he's greeted by a falling star that obliterates his new place of employment. Alongside Fernanda Méndez, a relentless optimist and star athlete who can outrun a train but can't quite outrun her own bad luck, Benjamin finds himself stranded in the wreckage. Their only hope for a ticket home to Mercury comes in the form of Akane Blackheart... a ruthlessly evil witch with the magical ability to solve problems by blowing them up.
From hijacking commercial space cruisers and dodging a relentless galactic inspector to accidentally becoming the world MMA champion through the strategic use of C4, Benjamin and Fernanda are dragged on a chaotic, cross-dimensional odyssey.
