On a surface level, at first glance, every Gears character looks like a stereotype. Very simple.
And as fans love to point out in regards to their favorite characters… Gears characters are not as simple as they appear. They express hopes, fears, dreams, regrets, and even doubt.
They’re actually archetypes, which is why Gears characters are so beloved, while most of their competitors from 2006-2012 are forgotten. Most memorable characters are defined archetypically, and appear to fulfill a stereotype (or create one, such as Gandalf creating the stereotypical wizard). But through their dialogue and actions, good characters reveal themselves to be deeper and more complex.
You forget that Gears 3 had the Thrashball flashback, which is a love-it-or-hate-it thing. I loved it, even though it was cheesy, because it showed what happens when Cole reaches the end of his rope. He blazes bright, and goes for the win even at personal risk. When he succeeded, he was reinvigorated.
In Gears 5, the motorcycle kill was Cole fulfilling his role. He makes the big plays that would get anyone else killed, lands his shot, and triumphs.
Then he tried to stop the Kraken with his mega-mech. And it didn’t work. He was too slow to eject from his mech (age catching up with him, and he was too confident). So he suffered a broken leg, internal injuries, and perhaps even a concussion. Not cheesy at all. It was a great use of the mega-mech, with a believable result.
And more importantly, it showed that mega-mechs aren’t powerful enough to win the war.
(if you think he couldn’t possibly survive, allow me to tell you about my great-great-uncle; his truck was hit by a train, he was ejected fifty feet in the air, and he survived unhurt)
