No, I’ll be down for that even more. But wouldn’t Char win still lol?
Im pretty sure Lelouche is better at commanding an army while char is just a more one on one type person or two v one person?
Lelouch is more of a military strategist and political leader than he is a fighter. Honestly, outside of hax, he sucks a lot in a 1v1 scenario. I think he has never won a 1v1 without some prep or backup. Most of his fights in the anime are him outwitting his foes through indirect means (prep time and manipulation), like Light Yagami (hence why he and Light get compared to a lot) or being a Jojo character with how well he uses his powers (Bs like erasing his own memories to beat a mind reader and predicting an entire conversation to make a fake video to fool someone.)
That's the reason why I want this to be an army fight, since it being a 1v1 is a huge waste of a character who is known for being smart. That way, Lelouch could showcase his leadership skills and create complex strategies to deal with Char's tech and Newtype BS. This also shows the more tactical aspect of Gundam.
As for who wins, Idk. Char likely has the larger army, but a lot of his best ships can't function on Earth. Char has newtypes like himself, Kamille, Quess, and Lalah, but Lelouch has troops like C.C., Jeremiah, Suzaku, and possibly himself (if you give him the code from the movie), who all can counter a Newtype's precog and telepathy. Jeremiah's Geass canceller would hard counter Char's connection to the psycho-frame, likely making his best mechs useless. Lelouch also has Kallen, whose mech is basically The Hand or Killer Queen from Jojo, with its right hand having busted durability negation, or Rolo, who can "time stop". As for superweapons, the Axis and colony drops are 100% non-standard for Char, and while the Damocles is more standard for Lelouch. Both also have tech hax like the Geftun disruptors and minovsky particles which cancel out.
Simply put, in an army fight, Lelouch gets access to hax that helps him a lot against Char, and his being a better tactician would benefit him greatly in an army fight. Char's only win is the Sazabi being far above any mechs Lelouch has, but Jeremiah gets to disrupt Char's connection to it and the Damocles one-shots if the nuke hits (given its AOE, it will). As for stats, I think both are city block-town level, but Char's Sazabi is city-island, while Lelouch's Damocles is Island level (with dura neg).
