6. Finn
Like General Hux, how you feel about Finn's powers probably depends on who you think he is. If he's Lando Calrissian's son (
something a rogue Amazon listing has suggested) he's probably not Force sensitive (unless it's revealed Lando had an affair with a Jedi), but if he's Mace Windu's son (who wasn't forcefully celibate), then he could be. Of course, there's the possibility that he belongs to an entirely different family, but the shrouding of his surname suggests it's one we've seen before. There's also the question of the lightsaber. Traditionally - though not exclusively - lightsaber use is limited solely to Force sensitive characters (Han Solo was the notable exception, but it's usually the exception that proves the rule). Though Finn is clearly not particularly skilled with his blade (he looks noticably terrified to be in combat with Kylo Ren), the very fact that he's using one is indication of something. Because of that, at the minute it's most appealing to suggest he's a second generation Jedi (or that he was manipulated genetically to gain powers - he does mention being born for a singular reason), which puts him firmly up the power scale. Unless he's a morality tale, and he's destined to be cut down for daring to think he could break the rules...
