The 21-year old utility made his first-grade debut in the final round of the season.
The talented youngster graduated from the Wests Tigers junior system, before stepping up to ISP in 2016.
The younger brother of rugby league veteran Benji Marshall, King insists that he want’s to do his ‘own thing’.
“He’s my brother, but you can’t just keep following him, you’ve got to do your own thing,” Marshall-King said before his debut.
“It’s given me a bit of inspiration, the stuff he’s done for the NRL and the club. Me coming through, it would be good to make my own footsteps through the club and not follow his, to do my own stuff.”
Although he’s not lining up alongside his star sibling, King hopes that he’ll get the opportunity to play against the 32-year-old.
“Hopefully we can verse each other, I’d love to play against him,” Marshall-King told Fairfax Media.
“There would be a lot of dirtiness, a lot of rubbing his face and that, but that’s just how it is with brothers.
“I just want to keep going with my NRL career and play as many games as I can.
“It will be the first time I get a chance to do a full pre-season with an NRL squad and I can’t wait to rip in.”

Marshall-King was Liechardt’s next big talent after he was utilized as a backline utility in the Tigers NYC squad in 2012. After a number of injuries, King walked out on the game and began playing touch-football in 2016.
King returned to the paddock in 2017, remarkably overcoming adversity to make his first-grade debut in the final round of the season.
