In gacha games, what players pay the most attention to is how certain characters perform and which ones are worth developing. This is also true for the new mecha strategy game based on the Gundam IP, "Gundam Steel Poem." Below, we will provide recommendations for character development in Gundam Steel Poem, telling you which units are worth cultivating. If you draw these units early in the game and develop them as core members, it will make the early stages more efficient.

Freedom Gundam:
An active group attack type Gundam, a major damage dealer. The active skill “All Cannons Fire” deals 120% (240%) attack damage to 2 random enemy targets. If a successful takedown (endurance reduced to 0) occurs, it can restore 100 energy points, with the effect triggering up to 2 times (4 times). A key point is that at Elite 1, it unlocks an additional 200% (240%) damage to burning enemies, significantly increasing its power.

Skill 2 increases endurance, crit, and speed. Skill 3 has a 15% (35%) chance to stun a random enemy for 3 seconds when an ally uses their ultimate. At level 81, it can unlock a bond, summoning the Justice Gundam to deal group damage when its HP first drops below 60%, while also gaining 20 seconds of damage reduction. As one of the most popular units in the series, its strength is undeniable, but to fully utilize its potential, it must be upgraded to Elite 1 and paired with units that can "ignite," which will be discussed later.

Justice Gundam:
The skill “Simultaneous Attack” deals 80% (160%) attack damage to all enemies, with a 40% (80%) chance to inflict a burning state (dealing 20% attack damage per second for 4 seconds). If the target is a melee unit, the burn damage is doubled. In terms of attributes, it increases endurance, armor, and attack.
The skill “Fate” is also crucial, dealing 50% (100%) attack damage to the current target, reducing 12% (25%) armor, and inflicting a burning state (dealing 20% damage per second for 15 seconds). The skill “Practicing Justice” increases skill damage and attack by 1% (2%) each time it is attacked by a target with lower armor, stacking up to 10 times.
It’s clear that the Justice Gundam's role is to apply burns and reduce defense, and it also has some offensive capabilities, making it an essential unit for the burn playstyle.

Archangel Gundam:
The skill “High-Speed Raid” attacks the nearest 2 enemies, dealing 110% attack damage to each, with a 60% chance to paralyze the enemies for 6 seconds, while also restoring 15% of its maximum endurance. The skill “Brain Quantum Wave Reaction” is an attribute buff, increasing endurance by 40%, armor by 50%, and block by 40%, and providing immunity to paralysis.
The skill “Shield & Thermal Saber” has a 20% chance to paralyze the attacker for 4 seconds when hit by a non-melee target. When hit by a melee target, there is a 35% chance to paralyze the attacker for 4 seconds. The skill “Super Soldier”: when its endurance first drops below 50%, the next attack deals 120% damage and gains 40% damage reduction for 10 seconds, recovering 6% of its maximum endurance per second.
The key is the “paralysis” effect, making it a necessary unit for the paralysis playstyle, using its strong control effects to create favorable conditions for teammates. It is usually used in combination with Z Gundam, X-1999, Unicorn, and ZZ Gundam.

Z Gundam:
The skill “Super Mega Particle Cannon” can be enhanced with the unit's star rating, increasing damage, and dealing extra damage to paralyzed enemies. If paired with units like the Archangel or X-1999, which have paralysis effects, it can further increase its damage output. The “Bio Sensor” unlocked at level 81 allows it to enter a self-sustaining combat mode, significantly improving its sustainability when facing multiple enemies, making the Z Gundam stronger in prolonged battles.

Astro Gundam:
The skill can cut through space, causing enemies to malfunction briefly, while also restoring a percentage of its attack as endurance to the team. It also has a self-rescue skill that restores its own endurance and increases healing. When its HP first drops below 60%, the next attack can remove debuffs, fully restore its endurance, and attack all enemies. This unit can be used in a malfunction playstyle, with other options including Seraphim, Albatross, Strike Rouge, and Dominion.
The units mentioned above are all worth prioritizing in the Gundam Steel Poem character development list. Freedom Gundam is the main damage dealer for the burn playstyle, while Justice Gundam is an excellent “igniter.” Then, the Archangel and Z Gundam can form a paralysis lineup, and Astro can pair with Seraphim for a malfunction team, offering a wide range of pairing strategies.
