Tasu Leech leads Kanjiklub, one of the two gangs that corner Han Solo aboard his bulk freighter in The Force Awakens. StarWars.com describes "a brutal street fighter" who "grew up on the Hutt colony world of Nar Kanji" and "refuses to speak Basic, dismissing it as a 'soft language for soft people'", preferring "to let his Huttsplitter blaster rifle do the talking".
His grievance is mundane and therefore convincing: Han has twice failed to deliver promised cargo. Between Kanjiklub and Bala-Tik's Guavian Death Gang, the sequence establishes that the thirty years since Endor have not made Solo a respectable man — he is still running the same debts, just to newer creditors.
