ABC will spin off series from three franchises next season — “Grey’s Anatomy,” “The Bachelor” and “Dancing With the Stars” — and add yet another Marvel-based drama, the network announced Tuesday.

The “Grey’s” spinoff will be set in a Seattle firehouse, with characters introduced on the flagship series next season. In addition, “The Bachelor Winter Games” will cast past contestants in a series with “winter-themed athletic challenges — including the toughest sport of all, love.”

Then this: “Dancing With the Stars Junior” will “pair celebrity kids and kids of celebrities with professional junior ballroom dancers.” No airdates set, but the reality series will premiere next year.

ABC executives also said the network will air a live comedy special produced by Jimmy Kimmel and Justin Theroux featuring comics reading scripts from classic sitcoms.

Here’s the fall lineup:

Monday: “Dancing With the Stars” (8); “The Good Doctor” (10), with Freddie Highmore as a surgeon with autism and savant syndrome.
