Every titan model will win, because a plasma railgun would one-shot every monster,the 40mm would need no more than 7 rounds(maybe 14 for behemoth) the Arc cannon would probably fry every monster in 3 shots(it’s what?10 times bigger than Markovs and isn’t a redesigned mining tool?), the chaingun would rip each monster to shreds before it got to the titan and the triple threat…9 balls from it would cover an entire S3 Goliath.
So I say- Titans win every time.
At close combat- the monsters would have a chance of scraping the titans(you know,since titans FALL from great distances=they can withstand a massive impact like “rock throw”,especially considering they have ENERGY SHIELDS)
a monster could maybe damage a strider titan, but I still doubt it(energy shield and still being able to sustain damage from titan weapons)
In short: technology wins!
EDIT: for all Kraken sympathizers- yeah,he could fry the systems for a while(maybe) and (maybe) overload the shields, but then what’s he gonna do? Attack them with his weak tentacles only to be grabbed by the neck and shredded apart?
don’t kid yourself guys, the titans can’t lose because they have defenses that just cannot be touched by any of the monsters.
