The underwater world has become more colorful as Disney Films has introduced new characters for their upcoming film "Finding Dory."

On June 17, Ellen DeGeneres's very forgetful but well-loved character Dory will return to the big screen for the sequel of the hit 2003 film "Finding Nemo." But she will not return on her own, since Nemo the clownfish (voiced by Hayden Rolence) and his father Marlin (voiced by Albert Brooks) will join her in her own adventure.

In the upcoming film, the usually alone Dory will find a family in Nemo and Marlin. But she will start having a persistent feeling that someone out there is still looking for her.

While looking for those to whom she was connected in the past, the blue tang fish will encounter several creatures when she finds herself inside the Marine Life Institute. Some of them are the octopus named Hank (voiced by Ed O'Neill)  and Destiny the blue whale (voiced by Kaitlin Olson), who happens to be an old friend of Dory's.

She will also meet the overly dramatic beluga named Bailey, voiced by Ty Burrell, as well as the lazy sea lions named Rudder and Fluke, voiced by Dominic West and Idris Elba.

Back in the big ocean, Dory will encounter Nemo's teacher Mr. Ray (voiced by Bob Peterson), who will let her become his teaching assistant. They will also reconnect with the migrating turtles Squirt (voiced by Bennett Dammann) and his father Crush (voiced by Andrew Stanton). They will also meet the loon named Becky (voiced by Torbin Bullock), who will take a liking to Marlin, as well as a group of cute and cuddly otters.

But Dory's ultimate goal is to be reunited with her parents Charlie (voiced by Eugene Levy) and Jenny (voiced by Diane Keaton). Based on the description from Disney, "Jenny may appear cheerful and a little flighty—but she's a protective mother and a smart role model. Charlie likes to joke around, but nothing is more important to him than teaching his memory-challenged daughter how to survive."

"Finding Dory" is slated to premiere in theaters on June 17.
