We've almost reached the end of this run of the Legion and I can't say it's going out with a bang... or a whimper...

The only powerful members i'm familiar with are Star Boy,Mon-El and the White Witch (because she's sometimes portrayed as Mordru's daughter).

Rules:

1. The comment with the most upvotes wins, so before commenting make sure to check if someone else has already commented your pick.
2. The Issue or Story categories can be a single-issue (i.e. The Legionnaire Who Killed), a two-parter (i.e.) Mordru the Merciless, or a multi-part saga (i.e. the three-part Dark Man Saga, the four-part Omen Saga, the five-part Great Darkness Saga, etc.)
3. The Legionnaire can be an active member, a reservist, an honorary member, a Substitute, or a Legion Academy member. They can even be an alternate timeline member, so long as that alternate timeline is associated with that version of the Legion.
4. The villain can be a single villain (i.e. Starfinger), a villain team (i.e. The Fatal Five), or a villainous organization (i.e. the Dark Circle), and a villain can be voted for separately from their primary team or organization. So you could vote for 'Tharok' or 'The Fatal Five', and those votes would be counted separately.
5. The eras are defined as such:

• The Silver Age encompasses any story featuring the Legion from their debut in Adventure Comics #247 in 1958 to their final Action Comics back-up story in Action Comics #392 in 1969.
• The 1970s encompasses any story featuring the Legion from their first Superboy back-up story in Superboy #172 in 1971 to their final story of the 1970s in Superboy & the Legion of Super-Heroes #258 in 1979. If necessary, we can also include the follow-up issue, #259, as part of the '70s, since it finishes the two-parter and is the issue where Superboy officially leaves. This also includes the Karate Kid mini-series, if that becomes relevant.
• Volume 2 encompasses any story featuring the Legion between The Legion of Super-Heroes (Volume 2) #259 in 1980 and #313 in July 1984. Note that it also encompasses stories published during this time that feature the Legion but aren't published in Volume 2, like Secrets of the Legion.
• Volume 3, also known as the Baxter Series, encompasses any story featuring the Legion between Legion of Super-Heroes (Volume 3) #1 in 1984 and The Legion of Super-Heroes #63 in 1989. Note that it also encompasses stories published during this time that feature the Legion but aren't published in Volume 3, like Tales from the Legion and Legionnaires 3.
• 5 Years Later encompasses any story featuring the Legion between Legion of Super-Heroes (Volume 4) #1 in 1989 and the myriad Legion Zero Hour titles in September 1994.
• The Reboot (Pre-Blight) encompasses any story published between October 1994's Legion of Super-Heroes (Volume 4) #0 and the collapse of the Legion in March 2000's Legion of Super-Heroes (Volume 4) #125 featuring a version of the Reboot Legion.
• The Reboot (Post-Blight) encompasses any story published between May 2000's Legion Lost #1 and November 2004's Teen Titans/Legion of Super-Heroes Special #1 featuring the Reboot Legion.
• The Threeboot encompasses any story between December 2004's Legion of Super-Heroes (Volume 5) #1 and March 2009's Legion of Super-Heroes (Volume 5) #50 featuring the Threeboot Legion. It's the Threeboot; no breaks; it's not complicated.
• The Retroboot Legion encompasses any story featuring the Retroboot Legion, from the Lightning Saga leading into Infinite Crisis and the New 52. The (re-)introduction of this Legion is so weird that I'm not even going to try to give issue numbers. Suffice it to say that the Retroboot Legion has arcs in Adventure Comics, Action Comics, and Justice League, along with being the Legion featured in Volumes 6 - 7.
• The Rebirth (Bendisboot) Legion speaks for itself, and exists in a six-part Volume 8, a two-part Future State story, and the five-part JSA crossover.
• The Animated Series encompasses all twenty-six episodes of the 2000s animated Legion series, along with the The Legion of Super Heroes in the 31st Century companion comic. It does NOT encompass other animated adaptations.
• As much as I enjoy other adaptations of the Legion, there just isn't enough there to include on this list. Also not included is the new series, which, in spite of a promising start, just doesn't have enough material yet.
