Mighty Avengers #19

This cover is a Skrullised version of Avengers #89 featuring the original Captain Marvel. The Skrulls in the window should be Rick Jones, Scarlet Witch, Quicksilver and Vision.

The story is inked by Danny Miki and Allen Martinez, and coloured by Dean White and Paul Mounts.

This story is not a flashback but happens within Secret Invasion itself.

Marvel Boy's war against Earth was described in his own mini-series, at the end of which he was imprisoned in the Cube. The Illuminati visited him in jail in their #4 and suggested he follow the example of Captain Marvel (Kree Mar-Vell) and become an Earth hero. In the Civil War: Young Avengers & Runaways mini-series the Warden brainwashed him to go after the Runaways, but he turned on him and took over the prison. In a tale in the SI: Who Do You Trust? 1-shot we saw him keeping the place peaceful until the Skrull tech-virus messed with *his* tech.

For Noh-Varr this issue overlaps his apps in SI:WDYT and SI itself. The opening section matches up with the WDYT story and his 1 page in SI#1, but here it doesn't mention the Skrulls or their Invasion. In WDYT we learned about him using his Plex AI and an Omniwave broadcast to control the prison. And that it was a Skrull that uploaded the virus. (Probably the virus that attacks Stark-tech everywhere else.) They all end with him leaving the Cube.

Captain Marvel (Khn'nr) was found in the Negative Zone by Sentry (in Civil War: The Return 1-shot) and was put in charge of the NZ prison. He made a brief public appearance in CW#7 and then renewed his superhero life in his own mini-series, at then end of which he discovered that he was a deep cover Skrull with false memories. He was conflicted but he joined the Skrull invasion force (in *his* tale in SI:WDYT) but chose to attack Norman Osborn's Thunderbolts as false heroes. That attack played out in SI#1&3 and TBolts #122, and ended at the start of SI#5 and TBolts #123 with Osborn trying to persuade him to help Earth. They both end with him flying away from Thunderbolts Mountain ...

.... which is where his action in this issue begins. This is the only place that records his fight with 2 Super-Skrulls. His attack on the fleet is also briefly seen in SI#5, but not his defeat. Marvel Boy finding him dying is also shown at the start of SI#6, which goes on to show Khn'nr telling Noh-Varr that Earth is worth protecting before he dies. And MB joins in the mass battle in SI#7 (albeit very near the end).

Noh-Varr will then briefly join Osborn's Dark Avengers as Captain Marvel before quitting, changing his id to Protector and later joining the post-Dark Reign Avengers.
