Best Starter Digimon in Cyber Sleuth
At the start of Cyber Sleuth you pick one of three partners — Palmon (Data), Terriermon (Vaccine) or Hagurumon (Virus). It matters far less than in most games: you can freely digivolve and de-digivolve, so any Digimon can eventually become almost any other. Pick what you like — here's how they compare. Data from grindosaur.

Palmon Data
Palmon's line leads to Rosemon and Rosemon Burst Mode, one of the strongest and most popular end-game Digimon. A great Data-type caster and the community favourite first pick.

Terriermon Vaccine
Terriermon is a Vaccine-type with the beloved Gargomon/MegaGargomon line and access to Rapidmon. A solid, well-rounded starter that beats the Virus-heavy early enemies.

Hagurumon Virus
Hagurumon is a Virus-type Machine Digimon that climbs to Machinedramon and other heavy hitters. Great if you like the machine aesthetic and hard-hitting attackers.
Which should you pick?
- Palmon is the classic pick for its Rosemon Burst Mode endgame, but honestly all three are fine.
- Because de-digivolution lets you rebuild any Digimon, your starter is really just your first project — you'll have a full team of anything you want soon enough.
- Aim your first partner at a Champion using the Digivolution Guide, and scan wild Digimon to grow your roster.
