Worst Characters to Keep in Invincible: Guarding the Globe

In Invincible: Guarding the Globe, the worst Elite characters to invest in and keep long-term are Martian Man, Flaxan Leader, Kursk, and Magmanite. These heroes suffer from low defensive stats, slow animations, or weak ability scaling that prevent them from performing well in high-difficulty campaign stages and Cecil's Nightmares.

Instead of holding onto surplus copies of these underperforming units, use them as promotion fodder within their respective factions to raise the rank caps of core carries such as Invincible, Titan, and Allen the Alien.

Faction Fodder Targets and Replacements

Ranking heroes from Elite+ into Exceptional, Epic, and higher tiers requires sacrificing duplicate Elite heroes from the same faction. Storing weak heroes slows account growth because progression in the campaign and GDA Ops directly dictates your idle resource generation rates.

Hero	Faction	Primary Flaw	Feed Toward
Martian Man	Worlds Beyond	Fragile base stats; displacement abilities pull danger toward your backline	Allen the Alien
Flaxan Leader	Criminals	Minimal support buffs, weak personal damage, and no defensive sustain	Titan or Doc Seismic
Kursk	Criminals	Sluggish cast animations that leave him vulnerable to interruptions	Doc Seismic
Magmanite	Criminals	Poor damage output combined with insufficient tank passives	Titan
War Woman	Earth's Defenders	Falls off in late-game scaling without offering defensive utility or sustain	Invincible or Omni-Man
Darkwing	Earth's Defenders	Low impact compared to higher-scaling damage dealers in a crowded faction	Invincible or Robot

Worlds Beyond: Martian Man

Martian Man functions as a disruptor, but he lacks the defensive stats needed to survive incoming damage when he engages the enemy frontline. His stretching abilities frequently draw hostile aggro directly toward your backline or leave him isolated without defensive buffs. Because Worlds Beyond food is valuable, feeding extra copies of Martian Man into Allen the Alien provides an immediate upgrade in frontline survivability and crowd control.

Criminals: Flaxan Leader, Kursk, and Magmanite

The Criminal faction contains multiple units that underperform in competitive team slots:

Flaxan Leader offers minor stat increases that do not compensate for his lack of survivability or offensive pressure in five-person teams.
Kursk possesses slow ability animations, making his electrical attacks prone to disruption before delivering meaningful burst damage.
Magmanite lacks both the damage mitigation to serve as a reliable solo tank and the burst potential to work as an off-tank bruiser.

Feeding these units directly into Titan provides your team with reliable invulnerability mechanics, while feeding Doc Seismic accelerates your access to wide-area stun chains.

Earth's Defenders: War Woman and Darkwing

Earth's Defenders is the most competitive faction on the roster. While War Woman offers early-game burst damage, her abilities lack team sustain and utility as enemy stats scale upward. Darkwing faces similar competition against the faction's primary damage dealers. Sacrificing extra copies of these units allows you to uncap high-priority anchors like Invincible, Robot, and Omni-Man.

Rules for Safely Consuming Duplicate Heroes

To avoid setting back your account, follow these guidelines before using any Elite unit as promotion material:

Keep one base copy for GDA Ops: Maintain at least one copy of lower-tier heroes if your roster cannot fully staff all concurrent background GDA Ops teams. Once your background farming slots are populated, treat subsequent duplicates strictly as promotion material.
Never sacrifice premier anchors: Do not use natural core carries or dedicated supports as fodder. Heroes such as Invincible, Robot, Omni-Man, Atom Eve, Monster Girl, Titan, and Allen the Alien should always receive food rather than be consumed.
Promote only within matching factions: Rank-up milestones require sacrifices from the same faction, so plan your fodder usage around whichever faction carry is closest to their next major level cap.
