You could use the villains that I know are shown in the comics, not all of them are great villains but there is mention of some that you can use from time to time to fill in, there are also the spin off comics of invincible that can help further expand the universe of this same , or use drama, the rex and eve thing can be used to complete a mini arc and make it a good arc
Have thought about adding more love interest for Mark. Amber wasn’t the only woman interested in mark both in show and comics. There’s also Eve, Anissa and possibly Duplikate. Also if Robot tries to create himself a new body, why not let mark use his viltrumite DNA to help him. This could help ensure robot’s loyalty.
Thanks for the update can’t wait for the next update I wonder how mark is going to stop the Viltrumite empire and grow stronger along the way I mean it’s always puzzled me why didn’t mark or Nolan get any equipment or armour for themselves to fight other Viltrumites I mean yes their Viltrumites themselves but the stronger like conquest and thragg are different all together a different breed.
