1. The DCEU Wonder Woman
"I've killed things from other worlds before," said Wonder Woman during her first major appearance in Batman v Superman: Dawn of Justice right before she went into battle with none other than freakin' Doomsday.
The DC Extended Universe version of Wonder Woman is the perfect blend between the classic warm and heartfelt character and the more modern, hardened warrior she has become. That much has been clear from Gal Gadot's journey as the character throughout the various DCEU movies she has appeared in - all of which have showcased her strength in some form or another. And what a showcase it has been.
Diana had the most success of the DC trinty when she, Batman, and Superman squared off against Doomsday, injuring him with her sword and subsequently holding him in place with her lasso. She then held her own against a super-charged Superman in Justice League before playing an important role in taking down Steppenwolf. Her greatest success, however, was in 2017's Wonder Woman when she single-handedly defeated her brother Ares, the God of War.
The DCEU iteration of Wonder Woman is literally a god and that makes her power-levels infinite. She's strong, fast, durable, and efficient just like all of her predecessors, but the sheer force she creates whenever she clashes her gauntlets together is unlike anything in any DC lore ever. She's so incredibly powerful, capable of stopping all kinds of threats and one of the most unstoppable entities to ever grace the big screen. Oh yeah, and she learned to fly, too.
This is an all-powerful God whose story was only just beginning when the DCEU came to an end. Here's hoping she's allowed to continue that story in the DC Universe.
