Cabba first learnt about his potential to transform into a Super Saiyan when he met Vegata and Goku from Universe 7. On his own planet, no one had ever achieved the form.

Vegata decides to mentor Cabba in battle in an attempt to unleash the transformation. He provokes Cabba by insulting him, but gets nowhere. It is only when he starts threatening Cabba's planet that his tactics pay off and Cabba finally transforms into his planet's first Super Saiyan.

After his encounter with Vegata, Cabba finds a way to use his newfound abilities for good. Back on his home planet, he recruits other Saiyans in the fight to protect their universe by teaching them the form.
