Raditz could fight Kurome from Akame ga Kill? Being the weaker and evil siblings of Akame and Goku.

Alternatively, he could take on Raven Branwen from RWBY. Again evil siblings, this time with the added connection of choosing to combat what their brother wanted to help (Earth for Goku and Huntsmen and Huntresses for Qrow).

For the simple 'sibling' connection, Luigi fits.

Sorry if none of them seem like a good idea.
