Digimon Frontier (デジモンフロンティア, Dejimon Furontia), known outside Japan as the fourth season of Digimon: Digital Monsters, is the fourth television anime series produced by Toei Animation based on the Digimon franchise. The series is noticeably different from other seasons as the main characters, the Digidestined, don't train Digimon to fight for them but instead merge with ancient spirits (known as 'Legendary Warriors') to become Digimon themselves.
The series aired in Japan between April 7, 2002 and March 30, 2003, with an English-language version, produced by Sensation Animation, airing in North America between September 9, 2002 to July 14, 2003. It was the last season to use the Digital Monsters title as subsequent series, beginning with Digimon Data Squad, began using unique localized titles.
Long ago, a group of ten Digimon sacrificed themselves to defeat an ultimate evil that threatened the Digital World. These Ancient Warriors created artifacts from their data, the twenty "Spirits" (ten Beast spirits and ten Human spirits, one of each for each element), before leaving the Digital World in the care of the three Celestial Digimon. However, one of the three, Cherubimon begins a reign of terror. To counter this, the Celestial Digimon Ophanimon summons six children (Takuya, Koji, Zoe, Tommy, J.P. and Koichi) from the human world into the Digital World via the train-like Trailmon.
We gathered with the lawyer for the reading of the will
Mama sat there quietly between all of us kids
Then he opened up the papers and my father's words were read
You could have heard a pin drop when we heard the things he said
"To all my loving family I leave this old house
Just split up all the money and pass it all around
But now that that's all settled and it's all said and done
Here's a few things that I'll leave with each and everyone"
"To the boys I leave the family name, the honesty and the pride
To both my precious girls, I leave a million lullabies
Sing them to your children and let them know you care
And take what strength I gave to you and be patient, kind and fair"
"To all I leave undying love, let no one shed a tear
'Cause I was the luckiest man on earth in the time that I was here
And finally to mother who's love was ever true
The greatest gift a man can give, I leave my heart to you"
We all just kind of sat there, not knowing what to say
Then Mama looked at all of us and said, "I?d like to pray"
So right there in that office in words so soft and still
