Tai's Digimon

  Koromon - Bubble Blow
Koromon is Agumon's former form. They have the same personality 'cept he talks and eats more. He pretty much sucks when he tries to fight since he can just blow stupid bubbles. 

  Agumon - Pepper Breath
This is Tai's usual Digimon, Agumon. He seems to be the leader of the DigiDestined's Digimon like Tai. He gets some of Tai's characteristics like being brave but also a little stupid sometimes too. He is the first at most things like Digivolving into 3rd and 4th levels. He looks like a T-Rex with a whiny voice. 

  Greymon - Nova Blast
Agumon's next form is Greymon. Greymon loses that weird voice of Agumon and goes "..Digivolved to GGGRRRRREEYMONN" instead. His Dinosaur body turns orange, NOT GRAY, and his head gets stuck in a helmet or something. He saves the day more than the other Digimon since he is used more, you know Tai is a show-off. 

  Metalgreymon - Giga Blaster, Mega Claw
This was the first ultimate Digivolution in the series. Like all other ultimates, it kicks ass (oh I cussed, whoopdee doo). It looks like a huge Greymon and a motorcycle had a baby and Metalgreymon was born. I think he can fly since he grows wings too. 

Matt's Digimon

  Tsunomon - Bubble Blow
Matt ::hears cheers:: first got this Digimon. Tsunomon is pretty weak just like the other de-Digivolutions. He looks like brown-orange ball with a black horn sticking out of its head. He is loyal to Matt. 

  Gabumon - Blue Blaster
Matt's main Digimon is Gabumon. It's sort of a multi-colored dog-like thing with a horn on its head. He is something like Matt's mentor. His attack, Blue Blaster, is used by him shooting out blue ice beams from his mouth. 

  Garurumon - Howling Blaster
Gabumon's next form is Garurumon. He now walks on all 4 legs so he can run pretty fast. Garurumon loses the pink and yellow stripes and spots and is now white with blue stripes. He looks like a half-wolf half-zebra. Like Greymon, their teeth grow huge. 

  Weregarurumon - Wolf Claw
On a full moon, Garurumon howls and Digivolves to..Weregarurumon! Okay so he doesn't. Gabumon stands on 2 legs, Garurumon walks on 4, but now Weregarurumon stands back on 2. He looks like a Garurumon on steroids and wears torn jeans. He looks like Rambo and can jump, kick, and pretty much whoop your ass. 

Sora's Digimon

  Yokomon - Bubble Blow
Sora's first Digimon form was Yokomon. Other Yokomon live together at a hot spring near a mountain guarded by Meramon. Yokomon sucks in fighting as much as the other pre-Digimon. It has very weird hair or whatever.
 
  Biyomon - Sprial Twister
A Chocobo in Digimon? No, it's just Biyomon. And no, it doesn't have any B.O. Biyomon is Sora's Digimon most of the time. She is a pink Chocobo-ish bird. She cares for Sora as much as she does for her. Her attack, Spiral Twister, is used when it flaps its wings making twisting green streams. 

  Birdramon - Meteor Wing
Biyomon's Digivolution is Birdramon. Its voice sounds so very bad. When you think Greymon has big teeth, well, look at hers. It looks a lot like Moltres from ::shudder:: Pokemon. It has very wide wings that got caught in fire. She is used as the group's jet. 

  Garudamon - Wing Blade
The ultimate Digivolution for Birdramon is Garudamon. And if you thought Birdramon sounded bad..ughhh, it's like a sick old lady. Like Weregarurmon, it walks on two legs and takes a human-ish shape. It grows muscles and strange drawings all over its body. To me it looks like Angemon on fire. It's very strong and rivals a 747.

Izzy's Digimon

  Motimon - Bubble Blow
This blob of jello was assigned to Izzy. It is weak and like the rest, needs to Digivolve to fight. It looks like a glob of pink stuff with arms. I thought it was a pink Puyomon with arms. He is pretty smart like Tentomon also. 

  Tentomon - Super Shocker
Izzy's Digimon usually is Tentomon. Tentomon is probably the smartest Digimon in the group. He looks like a robotic fly alien with buzzing wings. When Izzy gets too into his computer hacking stuff Tentomon tells him to try and have some adventure. His attack Super Shocker is used by zapping his enemy with his antennas.

  Kabuterimon - Electro Shocker
When Tentomon Digivolves it turns into Kabuterimon. It first Digivolved by "cheating". Izzy needed to hack the Digivice through his laptop and it Digivolved. Like Greymon, it too gets its head jammed in a mask. It has huge wings and big teeth too. It turns blue and it's legs grow longer. 

  Megakabuterimon - Horn Buster
Megkabuterimon's first appeared when Kabuterimon digivolved into his ultimate form in "No Questions Please". This is one huge bug. It's like Kabuterimon except it is enourmous and grows shell on its back. His horn grows bigger and can blow up things. 

Mimi's Digimon

  Tanemon - Bubble Blow
Mimi got Tanemon, the form before Palmon. It is weak too, as if any of the other pre-Digivolutions are. It looks like a green Tsunomon with a leaf on its head. 

  Palmon - Poison Ivy
Mimi's usual Digimon is Palmon. She has a green complexion with wrinkly leafs as hands and a flower growing out of her head. Palmon usually tries to talk some sense into Mimi when Mimi acts like a brat, actually she always does. Her Poison Ivy attack shoots out vines that wrap and whip stuff and can be climbed on.

  Togemon - Needle Spray
Palmon's next Digivolution is Togemon. It's a walking talking cactus like from Super Mario Bros. It has a lot of very sharp needles around her. Togemon has boxing gloves and can punch very hard. Her eyes and mouth are holes and her hair is fuzzy orange stuff. 

  Lillymon - Flower Cannon
Lillymon is Togemon/Palmon's ultimate form. She's pretty tiny for an ultimate (as she IS Togemon's former itty-bitty flower), but she does, however, still manages to beat up huge ugly strong other Digimon. Her Flower Cannon takes out strong Digimon like Dark Tyrannomon. She also seems have an attitude like Mimi's. 

Joe's Digimon

  Bukamon - Bubble Blow
Joe was first given Bukamon. It looks like some kind of tiny brown-gray seal with a broken nose and a mohawk. It can't do much really and needs to Digivolve to beat up others. 

  Gomamon - Marching Fishes
Gomamon is Joe's main Digimon. It is the total opposite of Joe. He always tries to get Joe to be have more fun [yeah right]. Gomamon prefers to be in the water more than land. He looks like a white seal with purple marks and a red mohawk. His attack is the weirdest one yet, Marching Fishes, and summons a rainbow of fishes to fly out. 

  Ikkakumon - Harpoon Torpedo
Gomamon's Digivolved form is Ikkakumon. He looks like a walrus with long shaggy fur, tusks, and a horn on his head. His attack, Harpoon Torpedo, is way cooler than Gomamon's Marching Fishes. It fires a rocket out of his horn and it shines it up real nice, turns it sideways, and blasts it straight up--oh um...Riiiight. 

  Zudomon - Hammer Spark
Ah! It' a turtle-dog with a hammer, run for your lives! Oh wait, it's just Ikkakumon's ultimate form, Zudomon. He hasn't appeared in the (English) series yet, so there's not much info on him. He carries around a hammer, which he uses for his Hammer Spark attack, whacking other Digimon on their noggan. Ya gotta love violence. 

T.K.'s Digimon

  Tokomon - Bubble Blow
This Digimon was assigned to T.K. It pretty much can't do anything really. It can however look tougher by showing off its sharp Birdramon-like teeth. It is weak like the other basic types. 

  Patamon - Boom Bubble
T.K.'s main Digimon is the very very very cute ::makes vomit noises:: Patamon. Patamon is the Pikachu of Digimon. He is the smallest and weakest Digimon like T.K. is the little guy. He looks like a hamster with bat-like wings. Patamon's attack, Boom Bubble, sucks since all it does shoot out air. 

  Angemon - Hand of Fate
Angemon is Patamon's Digivolution. Angemon was the one who defeated Devimon, then he went back to a DigiEgg. He looks like an angel [duh] with blond hair and a helmet to cover up his face. He also holds a golden staff [between his legs..o_O]. He is one of the most powerful Digimon and is used very (I mean very) rarely.

  Holy Angemon - ???
Holy Angemon is what you get when Angemon steals Wizardmon's hat and goes prancing around with it. ...Or it's Angemon's ultimate form when TK uses his Crest of Hope, near the end of the first season. Holy Angemon hasn't appeared in either Japanese or English series yet, so there's not much info on it. He's pretty strong, but that's just an assumption.
