SD Gundam G Generation ETERNAL Tier List & Reroll Guide – Best Units to Pick

SD Gundam G Generation ETERNAL is a strategic turn-based mobile game where choosing the right units makes all the difference. Each character plays a unique role, and selecting the top-tier units early on can give you a major advantage. In this guide, we’ll walk you through the best units to focus on, break down the full SD Gundam G Generation ETERNAL tier list, and show you how to reroll efficiently, especially with tools like OSLink to speed things up.

SD Gundam G Generation ETERNAL – S Rank

S rank in this tier list are the Gundam ETERNAL best units. They have the most versatile skills and strength levels than others and will be ideal in every situation. These units don’t show any weakness in any stage at all.

SD Gundam G Generation ETERNAL – A Rank 

When you have no S rank units in your hands, you have the A ranks to rely on. These are also considered as the very best units and they show utilities for any of the situations you are in.

SD Gundam G Generation ETERNAL – B Rank

B rank holds the good units, but they aren’t versatile. Sometimes, they show a certain lack of performance in several situations, so these are just perfect fits for beginners.

SD Gundam G Generation ETERNAL – C Rank

C-rank units are the worst. They have the lowest power than the others and will only show effectiveness in certain scenarios.

SD Gundam G Generation ETERNAL Recommended Units for Reroll

Even after the April 30 SD Gundam G Generation ETERNAL update, these are the top units to reroll for. S-rank units stand out with unmatched power and versatility, making them essential for tackling any challenge.

Here are the best ones we recommend starting with.

• Freedom Gundam (EX): Freedom Gundam (EX) is a flexible attacker with strong beam damage and great mobility. With Kira Yamato as its pilot, it lowers enemy ATK by 25% and works well on all terrains except the Sea. It’s one of the best units to reroll for if you want solid performance in both PvE and PvP.

• Gundam Exia (EX): Gundam Exia (EX) is a super fast melee unit with high critical damage. Its Trans-Am mode boosts damage by 30%, and Setsuna’s +1 Chance Step allows it to chain attacks, making it great for taking out groups or bosses in any stage of PvE or PvP.

• Phoenix Gundam (Power Unleashed): Phoenix Gundam (Power Unleashed) is a top-tier support unit that lowers enemy defence by 20% and heals allies. Amuro Ray’s buffs and 10% HP recovery each turn help keep the team alive, making it a key unit for surviving tough fights in PvE and PvP.

• Sazabi (EX): Sazabi (EX) is a top long-range attacker known for its 5-range Funnels (3,200 power, 21 EN) and Mega Particle Cannon EX (4,800 power, 43 EN), both of which ignore enemy defences. With Char’s +1 Chance Step and +1 Range, it can safely deal big damage from afar. Its power increases when HP is low, making it a top reroll choice for strong sniping in PvE and PvP.

• Gundam Aerial (EX): Gundam Aerial (EX) is an excellent support unit that applies DEF Down (15–25%) and increases Beam Damage Taken (25%) using a 5-range EX attack (4,800 power, 43 EN). Suletta’s +1 Range and EN recovery help it keep debuffing consistently. It’s great for both PvE and PvP and a smart reroll pick for strong team support and clearing hard missions.

Conclusion

So these are all the units in the SD Gundam G Generation ETERNAL tier list you can go for. Once you’ve picked your targets, reroll smart, use tools like OSLink to mirror your progress across multiple accounts and speed things up. Less grind, more chances, and a quicker path to victory.
