The Londerz Family, originally called the Dolnero Family, are the antagonists of Mirai Sentai Timeranger.
Founded by Don Dolnero at some point in the year 3000, their leader was later captured and incarcerated in the Londerz Prison. However, he escaped with help from his subordinates Lira and Gien. After commandeering the prison, the Dolnero Family traveled 1000 years into the past to the year 2000 where they renamed themselves the Londerz Family. With the other prisoners of the Londerz Prison at their disposal, the Londerz Family sought to begin a new crime wave in the past.
However, they faced opposition from a group of time cadets who traveled to the past to pursue them, the Mirai Sentai Timeranger.
The Londerz Family later collapsed after Gien's insanity led him to betray and kill Dolnero. Taking control of the remaining forces of Londerz, Gien began a campaign of destruction until he was destroyed by the Timerangers.
The only members to have survived were Lira and a couple of Zenitts, though the former's exact fate is unconfirmed.
