"Gary Jr." src

Marchosias is a powerful hellhound who masqueraded as a common dog and was adopted by Gary Green after his trip to Hell. He began manipulating him until he was stopped by Sara Lance.

Marchosias was born in Hell at some point in ancient times, being known as the Canine of Chaos. In the 70s, he was the one who manipulated the Son of Sam into becoming a serial killer.

In 2020, Gary Green escorted Constantine to Hell where he saw Marchosias who was masquerading as a Terrier dog. Believing him to be an innocent dog, he took him for himself, renamed him as Gary Jr. and returned to the Waverider.

However, Marchosias put in action his evil plan, manipulating the Legends to do his own comands, also preventing them to remember what they did: Clotho hid the Loom of Fate's pieces while Nate Heywood sabotaged the timeship.

Sara Lance began to suspect Gary Jr. after seeing into the future, Marchosias tried to corrupt her but she was not subject to his will. Constantine made the hellhound reveal his true form and almost defeated him, forcing the evil beast to escape and try to attack Mick Rory and his daughter, Lita. As Sara made him run again, Astra Logue provided Gary Jr.'s real name so that Constantine used it to cast a spell to banish him again to Hell.[1]
