But having inherent super strength must be a bonus, surely.

If you have a Lantern ring you can make yourself as strong as you want.

It's a wonder why assclowns like Kyle Rayner and Guy Gardner get rings while the goddamn Batman doesn't. Superman almost got one but it realized he wasn't native to the Milky Way, which is reasonable, but it should have made a beeline straight to the Dark Knight immediately after.
