Consider that they could be easily implemented into the TL during the Onslaught/ Heroes Reborn or Infinity Gauntlet , House of M or newuniversal events as replacements that snuck in with the idea that some nigh godlike power (e.g. Franklin Richards, Wanda Maximoff, Rachel Summers) placed them into the TL, as a means to supplement or help the major heroes. Consider X-O Manowar was supposed to be the replacement for Iron Man. Bloodshot can be seen as the replacement for Captain America. Eternal Warrior can be seen as a replacement for Thor. Ninja at one point was a child merged with a video game character, so he can easily be linked to Spiderman..Anyone have any suggestions on how to incorporate the following characters into the Marvel Universe: Harbinger, X-O Manowar, Shadowman, Archer and Armstrong, Eternal Warrior, Bloodshot, Ninjak, and Rai?
