Krillin is a recurring playable character across the Dragon Ball Z Budokai and Budokai Tenkaichi fighting game franchises. In these titles, he utilizes his signature techniques such as the Destructo Disc (Kienzan) and Solar Flare. His character campaign and movesets reflect his role as a key ally and martial artist throughout the adapted Dragon Ball Z storylines.
In the 2.5D fighting system of
Dragon Ball Z Budokai (2002), Krillin's gameplay emphasizes quick hand-to-hand combos and capsule customization, allowing players to equip various physical and energy skills. By
Dragon Ball Z Budokai 2 (2003), his role expanded within the board-game-style Dragon World mode, where he can fuse with Yamcha to form the hypothetical character "Gokule" under specific conditions. This customization deepened in
Dragon Ball Z Budokai 3 (2004) and its
Dragon Ball Z Budokai 3 - Édition Collector (2005) through the Dragon Universe RPG mode, which tracks his progression from the Saiyan saga to the Majin Buu era.
With the transition to behind-the-back 3D arena combat in
Dragon Ball Z Budokai Tenkaichi (2005), Krillin's mobility and aerial combat options were redesigned to fit larger environments. In
Dragon Ball Z Budokai Tenkaichi 2 (2006) and
Dragon Ball Z Budokai Tenkaichi 3 (2007), developers expanded his roster presence by including distinct playable variations, such as his early childhood form, alongside his traditional appearance. These iterations feature tailored stat balances, reflecting his scaling power levels relative to larger, more powerful opponents.
