I think that "Tiny Toon Adventures" & "Animaniacs" are the 1990's descendants of Looney Tunes,
because their humor, their characters' personalities, & their comedic dialogue have always reminded us
of the pre-1965 classic era of the "Looney Tunes" & "Merrie Melodies" cartoons.
& according to these details, their forms & personalities/behaviors shows that they have
an official relationship (not blood relationship) with the original cast of Looney Tunes.

Fact: The Tiny Toons counterpart of Looney Tunes' Speedy Gonzales is named Lightning Rodriguez,
& originally he was going to be the recurring character of "Tiny Toon Adventures", but his recurring role
was cancelled during production due to the cartoon staff's reasons, but he did have small appearances in
the 2 episodes "You Asked for It" & "The Acme Bowl".
& Another Fact:
Although "Tiny Toon Adventures" was the 1990's version of "Looney Tunes",
there are new original characters created for this show:
Shirley "the Loon" McLoon (a Tiny Toons version of the new age believer, Shirley MacLaine).
(note: Shirley MacLaine was Shirley the Loon's idol)
Arnold the Pit Bull (based on Arnold Schwarzenegger, like Jorgen Von Strangle from "The Fairly OddParents").
The evil rats named Roderick & Rhubella.
Mary Melody (her name is based on the name of WB's other theatrical cartoon series "Merrie Melodies").
Byron Basset.
Mr. Skullhead.
"Animaniacs"
Yakko, Wakko & Dot are based on the characters of the black & white Looney Tunes & Merrie Melodies cartoons of the early 1930's
(Bosko & Honey, Foxy & Roxy, Goopy Geer, & Piggy & Fluffy).
Slappy Squirrel was an old retired cartoon character who once had fame & glory as the star of the "Looney Tunes" & "Merrie Melodies" cartoons,
But although she is octogenarian and is on retirement, she can still outwit the enemies & fight back at them with cartoon violence.
Pinky & the Brain are beloved cartoon villains that are scheming diabolical deeds but are always foiled, humiliated & damaged in the end,
like Looney Tunes' Yosemite Sam, Sylvester (when he's against Tweety & Speedy), Wile E. Coyote (& Ralph Wolf) & Marvin the Martian.
& Brain's genius plans always backfires on him and Pinky, like Wile E. Coyote.
