The following contains spoilers for Shadow War: Omega, now on sale from DC Comics
The reveal that Geo-Force was the Deathstroke imposter who set off the events of Shadow War by killing Ra's al Ghul means the story's final battle was always going to be everyone versus the DC earthbender. But while he uses the chance to show off how powerful he can really be, Geo-Force also can't stop himself from giving up a surprisingly easy victory.
Shadow War: Omega (by Joshua Williamson, Stephen Segovia, Mike Henderson, Howard Porter, Hi-Fi, and Troy Peteri) revealed Geo-Force's ultimate move. He created a titanic body of stone to pilot around like a rocky mech. However, it turns out this move has a lot of drawbacks that suggest it's really a waste of an attack.
Geo-Force's powers quietly make him potentially one of DC's most dangerous forces, with multiple other sources over the years highlighting how powerful someone like him is. In the past, he and his sister Terra have been shown to cause severe damage to others and the surrounding Earth with their Geokinesis. In shows like Young Justice, Geo-Force proved how lethal his control over the Earth really makes him. In one of the realities from Tales of the Dark Multiverse, his sister Terra (who shares very similar powers to him) was amplified to his level and ended up with enough power to kill Superman and ruin the world. His sheer destructive potential makes his apparent ultimate form very dangerous.
While trying to kill Batman, Talia, and the rest of their allies in the Shadow War's conclusion, Geo-Force initially seemed to be on a similar path to his sister. The former hero unleashed waves of molten lava and massive stone to fling at his enemies and former allies alike. When that failed to cause any permanent damage to his enemies, he instead built himself a truly titanic body out of pure rock, making himself absolutely massive and potentially unstoppable. But despite the strength and durability, such a form should grant him, it turned out this ultimate move is actually something of a waste of potential.
The Titanic form may work against waves of League of Shadows ninjas, but it proved too slow to hit a far smaller target with agility. Despite nominally having been mortal with no enhanced strength or speed, the assembled heroes are able to stay ahead of Geo-Force's titanic attacks. Likewise, his newfound height made it harder for him to strike at an enemy who's far smaller and more nimble.
The massive stone body initially appears as if it would be able to withstand some punishment or protect Geo-Force from his opponents. But Robin was able to goad Geo-Force into revealing himself, allowing the young anti-hero to scale the titan, make his way to the former Outside, and knock him out in one good hit defeating the titan even though such a threat should have honestly been a Justice League-level threat.
It's kind of shocking that Geo-Force's ultimate move ultimately does very little for him in battle. If he'd remained on the ground and kept fighting Batman directly, his advanced training as a veteran of the Outsiders could have come in handy. Geo-Force could have had a better shot at catching a lucky hit against any of his targets. Instead, Geo-Force went for broke and removed his own flexibility, speed, and skill. His ultimate move might have been less dangerous than Geo-Force just normally using his powers. This speaks to both his untapped dangerous potential and the kind of short-sighted mistakes that can change the tide of a battle.
