The Metabarons is heavily inspired by and can be seen as a Spiritual Successor to Dune. The Shabda-Oud are the Bene Gesserit devoid of any concern for humanity's growth or future, the Technopriests are the Harkonnen with heavy doses of the Tleilaxu, and the Metabarons themselves are the Atreides with even more tragedy.
When comparing the initial premises, you can see that second volume of Young Avengers is one for Runaways - in both we have group of superpowered teenagers on the run, who cannot count on help from their parents (in Runaways because their parents are the bad guys and in Young Avengers because the Big Bad can easily mind control adults to kill them) and both series explore relationships between kids in their late teens. Also, in both groups one of the kids is secretly evil.
It also draws some of its tone, and a couple characters, from Joe Casey's Vengeance.
Tintin: Its style was widely imitated in the European comic strips scene. Especially the work of Edgar P. Jacobs (Blake and Mortimer) and Bob De Moor show this. Not surprisingly, both artists worked as assistants to Hergé.
A lot of comic strip authors for the Belgian comics magazine "Spirou" had a very similar looking style, inspired by André Franquin. They were even nicknamed "The School of Marcinelle".
Nero: In terms of drawing style, black comedy and surrealistic stories in a Flemish setting Urbanus is the spiritual successor.
Bryan Lee O'Malley's Seconds is one for his previous book, Scott Pilgrim, with the emphasis on zany humor/characters, heavy amounts of characterization, an aesop based around personal responsibility and a very Animesque art style.
Peter David's Fallen Angel is one for his Supergirl run, so much so that the heroine was initially hinted to be Linda Danvers (Supergirl's civilian identity) under an assumed name. This connection was abandoned when the series changed publishers.
Warren Publishing's 1960s horror comics such as Creepy Magazine, Eerie Magazine, and Vampirella were spiritual successors to the horror comics produced by EC Comics in the late '40s and early '50s like Tales From the Crypt and The Haunt of Fear. The EC comics had vanished in 1954 due to The Comics Code banning all violent imagery and macabre themes from comic books; Warren exploited a loophole by publishing its comics in magazine size (10.5" x 8.5", as opposed to 10.25" x 7" like a regular comic) in order to feature mature content while the Code was still in effect.
Champions (2016) is considered to be this to Young Avengers, due to the fact that both are teams of young heroes including a member related to Vision (Wiccan and Speed in Young Avengers and Viv in Champions) and following a major Bendis penned event in Civil War 2 vs Avengers Disassembled.
Every decade, Marvel attempts to create a new hero to serve as this for Spider-Man with varying degrees of success. In the 1970s they tried this with Nova. In the 1980s they tried it with Speedball. In the 1990s they tried it with Darkhawk. In the 2000s they tried it with Amadeus Cho (who even debuted in Amazing Fantasy V2 #15 to drive the parallels home even farther), and in the 2010 they tried this with the second Nova and the second Ms. Marvel.
Batman: Creature of the Night is a followup to Superman: Secret Identity, a Kurt Busiek-written series set in the "real world", following the life of someone who shares a name with as a DC hero, only to find the similarities don't end there.
Teen Titans: Earth One is a reimagining of the Teen Titans as a group of only-child runaways who develop superpowers, discover that their parents are evil, and run away to form a found family. AV Club pointed out that it was "heavily reminiscent" of Runaways
Since the heroes (with the exception of Raven) all have a connecting origin story as science experiments, one could also draw comparisons to All-New Ultimates.
