Given their personal strengths and personalities, who would make the strongest Green Lantern and whose powers in combo with the ring would make them strongest.

1. Kal-el, of course. We've seen him as a candidate and one in the far future as Superman Prime living in the sun.

2. Goku, right after the Tournament of Power.

3. Jiren, same time

4. Adult Naruto, with the Nine Tails

5. Current Ichigo

6. Cartoon Invincible

7. MCU Captain America


One might do the same with villains as yellow Lanterns if you want.
