The original Dragon Ball had various ki attacks and special moves like the Kamehameha, but the battles were still relatively grounded compared to what was to come. Dragon Ball Z changed everything with the introduction of transformation for the characters, with Goku getting the first in the series known as Kaioken. This transformation can be very useful, but also has a cost and this guide will tell you how to activate it.
How to transform into a Kaioken
Kaioken is not available to Goku at the start of the game, but is instead part of the main story. After returning from King Kai, Goku will face Nappa and have to beat him. This fight is relatively easy, but Goku definitely needs some help taking down his new rival Vegeta.
The game introduces you to the Kaioken right at the start of the Vegeta fight, instantly putting the move into your transformation bar. This is similar to the super attack palette you need to set, you can adjust it later.
To transform in battle, simultaneously hold L2 and R2 on PS4 and select the corresponding button for Kaioken. Once Goku transforms into a Kaioken, Goku receives a boost that gives him an edge in the fight against Vegeta. However, you need to be careful how you use him, as his health and ki-meters will also start to deplete in Kaioken.
This is one of those risk versus reward scenarios, so see if you need it against Vegeta and be careful not to overwork yourself and run out of health without even noticing how weak you are.
