Summary
He lied about being a superhero. You lied about not having freaky ass mind powers. You broke up- bitterly. End of story. No shot Invincible and some superpowered grunt for Machine Head would ever work out in any reality. Except. When he comes in droves, hoards of himself, brokenhearted and wanting, wrecking cities for a chance to get one last glance at you.

Summary
Nolan Grayson does not want his son's first interaction with True Viltrumite Culture to be when he wipes all governments off the Globe - so instead, he calls his mother - the mighty Thula Greis of Clan Uun, Krolulvek-Kraanvek (the World Breaker) and asks for her advice. The plan? Take Mark on a more kosher conquest of an Evil Empire, so he feels more ingratiated to the Viltrumites.
Thula sees an opportunity to ensure her line doesn't end, and calls her protege (and Nolan's Niece) to come help - the Djanchi Anissa Vokar of Clan Tazareth

Summary
Viltrum puede ser muchas cosas a ojos y oídos externos, Mark lo sabe de primera mano. Un mal augurio. El fin del mundo. Desde que se enteró de la verdad en unos de los momentos más dolorosos de su vida tras enfrentarse no solo a su padre sino a otros de su misma especie, algo dentro de él se fortaleció. Una promesa, inamovible, repetida en voz alta más veces de las que querría. No será un guerrero más. No será un conquistador al servicio del Imperio. La Tierra, su hogar, es la prioridad. Sus habitantes y la esperanza de un mañana mejor, lo que ilumina su convicción de seguir adelante hasta el final. O eso creía hasta que la persona que menos esperó, que usaba ESE uniforme blanco, le presentaba una perspectiva diferente. No quiere aceptar pero el Imperio, el universo y el futuro no espera a nadie.
(AU viltrumita William Clockwell x Mark Grayson)

Summary
There was no sign of mom at the house. Which was either a very good sign or a very, very bad one. He couldn't focus on that though. He needed to find her and take her back to his dimension. That would set everything right, and he could make up for his mistakes. He just need to find her...
Is that a purple skinned child? It couldn't be who he was thinking of... could it?

Summary
Viltrumites had believed in strength for so long that the few scientists among them were respected just for that. When one such scientific Viltrumite lands on Earth, Vigil is there for more than just its scientific studies, but the reason as to why events took such a turn. Why Nolan had departed so suddenly after a thousand years of service, the contradictions of Mark Grayson and why Earth was proving to be so anomalous to all other planets in the Viltrum Empire.
He was there to study it before Thragg undoubtedly ordered someone to burn it all away. Yet, in his observation of Mark Grayson, he was no longer sure it would be Thragg first.
Or, in general, my take on the rise of Sinister Mark.
