SD Gundam G Generation ETERNAL Reroll Guide and Best Units

When rerolling in SD Gundam G Generation ETERNAL, prioritize high-mobility, long-range mobile suits with balanced damage profiles and strong Space and Ground adaptability over single-target melee fighters. Your stopping point is landing at least one premier long-range carry—specifically Nu Gundam or Sazabi—paired with either a secondary high-grade unit or a matching signature pilot.

Step-by-Step Reroll Procedure

Resetting a guest account after the tutorial summons lets you secure key units before committing time and upgrade resources. Follow this sequence:

Launch the game using a guest account, declining third-party account link prompts to allow clean local resets.
Complete the initial combat tutorial and skip dialogue sequences to save time.
Open the operational inbox to claim pre-registration gifts and launch campaign currencies.
Spend all available pull currency on the primary launch banners.
If the pulls fail to yield a top-tier carry, open the system settings menu to reset account data, or clear the application cache in your device settings, then repeat from step 1.

Once you obtain a top-tier ranged unit alongside a matching pilot or second high-rarity unit, stop rerolling. Chasing three or more top targets is unnecessary, as standard progression includes farmable unit development paths.

Best Reroll Targets and Unit Rankings

Units that rely on short-range melee attacks must waste movement points crossing the grid and frequently suffer counterattacks. Premier units feature multi-target skills, all-range funnels, or broad coverage weapons that strike without exposing your squad to immediate danger.

Unit	Damage Profile	Primary Strength	Priority
Nu Gundam	Mixed (Beam / Special)	Long-range Fin Funnels, high survivability	Must-Have (Tier 0)
Sazabi	Beam & Funnels	High burst damage, broad area-of-effect strikes	Must-Have (Tier 0)
Freedom Gundam	Beam / Physical	Multi-lock EX skills, superior flight mobility	Tier 1
Wing Gundam Zero	Heavy Beam	Wide line AoE via Buster Rifle	Tier 1
Gundam Barbatos	Pure Physical	High single-target melee burst; limited reach	Tier 2 (Situational)

Nu Gundam and Sazabi are the premier reroll targets. Nu Gundam uses Fin Funnels to hit targets across long distances while ignoring standard line-of-sight barriers. Sazabi provides wide-area funnel attacks and sturdy defensive stats to anchor your squad line. Freedom Gundam is an alternate carry, using high mobility and multi-lock EX skills to clear groups of grunt units.

Pure close-range units like Gundam Barbatos and Gundam Exia deal high single-target physical damage, but their lack of reach forces them into hazardous counterattack ranges. Use them as secondary brawlers rather than your initial account anchor.

Account Evaluation Criteria

Before keeping an account, check that your roster meets three core tactical requirements:

Terrain Adaptability

Terrain ratings range across Space, Ground, Water, and Sky. Forcing a mobile suit into an environment where it holds a B rating or lower causes severe penalties to hit rate, evasion, and movement tiles. Flagship Universal Century suits like Nu Gundam and Sazabi hold natural S or A ratings in both Space and Ground, allowing you to clear early story operations without needing external flight support or terrain parts.

Balanced Damage Types

Enemies in early progression feature defensive traits that completely mitigate specific damage categories:

Phase Shift (PS) Armor: Substantially reduces incoming physical ballistic and blade damage.
I-Field Barriers and Anti-Beam Coatings: Absorb standard beam weaponry.

Relying entirely on one damage type creates severe progression bottlenecks against specific boss types. Nu Gundam and Freedom Gundam prevent this issue by carrying hybrid loadouts that feature both beam attacks and physical or funnel options.

Pilot Matching and Warship Synergy

A top-tier mobile suit requires a compatible pilot to reach full combat potential. Pilots provide passive stat bonuses, awakening values, and character skills that trigger when paired with their signature machine or affiliated series:

Nu Gundam: Pair with Amuro Ray
Sazabi: Pair with Char Aznable
Freedom Gundam: Pair with Kira Yamato

Finally, check that your roster fits within the squad capacity and deployment boundaries of your initial flagship, such as the White Base or Archangel. Warships provide repair support, deployment radii, and leader area stat bonuses that keep your squad functioning across extended missions.
