It’s Lor-Zod taking on the roll of Vegeta, as he appears in my own video series “What if Kal-El was Goku.” You can find part 1 here: https://www.youtube.com/watch?v=bbJf7wikpjY&t=906s
And Zod himself appears here: https://www.youtube.com/watch?v=Q0GzABattkE

I based his design on the son of Zod Superman from Gods and Monsters.
