Frog is a character from the Super Nintendo Entertainment System and Nintendo DS role-playing game Chrono Trigger. He is also known as Glenn, a soldier for the Kingdom of Guardia in 600 A.D. Magus and his minions cast a spell on Glenn to turn him into a frog.


The Queen is Gone

While Crono and Lucca visit the Cathedral in search of Queen Leene, they find Frog, who joins their party. After battling some of the monsters, they finally find the real Queen Leene. As it turns out, Yakra has been masquerading as the Chancellor. Yakra was the one behind the Queen's kidnapping.

Crono, Lucca, and Frog defeat Yakra and bring both the Queen and the real Chancellor back to Guardia Castle where they find Marle has suddenly reappeared. Knowing the Queen is finally safe, Frog decides to head back out on his own, leaving the others behind.

Tata and the Frog


Frog's hideout.

After acquiring the broken blade of the Masamune and getting the Hero's Medal from Tata, Crono and his party head into the Cursed Woods and find Frog's hideout. Frog, ashamed of himself for not being able to protect Queen Leene, gives Crono the hilt to the Masamune. They notice that Melchior's name is engraved on it. Wondering why, they decide to go ask Melchior himself back in 1000 A.D.

The Masamune!

Later, Crono and his party arrive back at Frog's hideout. This time they present the repaired Masamune to him. Crono convinces him to join his party and help defeat Magus. Together, they travel back to The End of Time so Spekkio can grant Frog the power to wield magic.

Jumping back to 600 A.D., the party heads for the Magic Cave. Using the power of the Masamune, Frog opens the rock entrance to the Cave. They journey through the underground tunnels battling strange monsters and emerge on the central continent, where the only thing that stands is Magus' castle.

Note: This chapter of the game has two flashback sequences in which the player gets a glimpse of Frog's past. Frog was a long-time friend of Cyrus. After Cyrus became a Knight fighting for the Kingdom of Guardia, Frog (then a human named Glenn) journeyed with him on many adventures. During an encounter with Magus, Cyrus is killed and Glenn was transformed into a frog by Magus' power.

Magus' Castle

Crono and his friends enter Magus' Lair only to find that they have to battle over 100 monsters. Along the way, they confront Magus' henchmen Slash, Flea and Ozzie.

After a seemingly long journey through the castle, they finally find Magus, who is chanting in an unknown language to summon Lavos. Even though Frog is wielding the Masamune, Magus is confident he can win the battle.

Throughout the fight, where all the fighters use magic, the Masamune's power weakens Magus enough that he drops to his knees, ending the battle. Reality suddenly seems to warp around them. Lavos' power creates a Time Gate. Magus and Crono's party members are all sucked into the Gate.

Forward to the Past

Crono and his friends awaken to find themselves in Ioka Village in 65,000,000 B.C. Ayla explains that she found them laying in the Mystic Mountains hurt. So the Time Gate in Magus' Lair ended up transporting them back to the Prehistoric era. But Magus was nowhere to be found.

Note: At this point, the player has more party members than spots in his party. Crono will remain the leader of the party, and the other two members can rotate out at any time. The characters not in the party will wait at the End of Time until the player needs them.
Frog's involvement in the following chapters depends on whether or not the player has him in their party.
