Tyreese is always willing to pitch in and help his friends, and unlike pain the ass Carl Grimes or basic bitch Beth Greene, he does a lot more than eat pudding or sit around singing "Kumbaya" like there isn't a zombie apocalypse happening.
You know how most millennial men supposedly can't change a tire or a lightbulb or fix a leaky faucet and other simple tasks around the house? Tyreese can do all of those things, then bash a walker's brains it with the same tool. It's almost like he was born in a Home Depot parking lot or something, but minus the potential complications and defects that are associated with giving birth in a wheelbarrow.
You know the lame stereotype that men never ask for directions? Tyreese never asks for directions because he is a master navigator and can even find his way around an unmarked forest. You'll never be late to your sister's wedding or niece's graduation if you have him at the helm.
