Anelle was introduced in 1965 as the daughter of ruler Dorrek VII, who debuted two years earlier.
Titannus was introduced in 2005 as a Skrull who lacked his species’ natural shapeshifting ability, but gains super strength and enhanced healing after taking part in the Super Skrull experiments.
As for Titannus, no doubt he would serve as the main Skrull “muscle.”
Given that Mar-Vell will reportedly be a major player in the Captain Marvel movie, perhaps we could see a similar scenario unfold in the MCU.
