That would depend on which game you're talking about.

You can't, you have to catch a tsnomon first then digivolve it.
By digvolving WereGarurumon (Blue), that is the ultimate form of Gabumon.
You can start the game with either Agumon or Gabumon, depending on how you do answer Jijimon's questions in the beginning of the game. The second question is the one that determines your partner, choose the first option if you want an Agumon or the second one if you wish a Gabumon.
It depends on how you look at it. Gabumon's attack is fairly simple, but it can be strong at times. Also, Patamon's attacks are also fairly simple. But look at Garrurumon. He's PRETTY STRONG. And Angemon is also really strong. But when comparing their attacks, I thnk Angemon would win in a battle. But Howling Blaster is really powerful. But, Angemon has more attacks than Garrurumon. I just realized that I got in a debate with myself if Patamon was stronger than Gabumon. But to tell you honestly, I think Gabumon is stronger than Patamon. But Angemon would be stronger than Garrurumon. But just by a little bit. Angemon must have a miracle of some sort to defeat Garrurumon. I remember hearing on the Digimon show that Garrurumon's fur is legendary and made of steel. So, that's how I look at it.

He helps Drimogemon in the treasure hunt cave. Recruiting him to the city will boost the chances of getting better items.
Normally, you can catch the In-Training form of your starter at the Data Forest. So, if you chose Agumon in the beginning of the game, you can get scan data from a Koromon there and evolve it into another one. If you didn't, there's another way. Enter the password 20000630 near Mr. Gure to get scan data from DotAgumon, then degenerate and evolve it into an Agumon.
Agumon and Gabumon were not the only Digimon to warp digivolve; however, they are among the most iconic examples from the original series. The portrayal of warp digivolution was likely influenced by budget considerations, but also by storytelling needs to showcase the characters' growth. The limited number of warp digivolutions in the early series helped maintain a sense of rarity and significance for those transformations. Overall, it was a combination of creative choices and production constraints that shaped their role in the story.
You get Gabumon once tsunomon digivolves. I would try to get a garurumon or were garurumon before advansing any further. WHOH! WHOH! did you answer the wrong question or something? COME ON! Oh, sorry. It's ninja wars, not HOS. They are from different time periods. never meet.
To obtain Seadramon in Digimon World Dusk, you need to digivolve a suitable Digimon that meets the requirements. Typically, you can digivolve a level 20 or higher Aquan-type Digimon, such as Gabumon or Gatomon, into Seadramon. Make sure to fulfill the necessary stats and conditions required for the digivolution. After successfully digivolving, you can train and battle with Seadramon to enhance its abilities.
The attacks were Pepper Breath for Tai's Agumon, Blue Blaster for Gabumon, Marching Fishes for Gomamon, Super Shocker for Tentomon, Spiral Twister for Biyomon, Poison Ivy for Palmon, Boom Bubble for Patamon and the last ones are Putty Howling and Petty Punch which were attacks for Salamon, the Rookie-level form of Gatomon, Kari's Digimon partner.
