GP02A-Like AoE Blaster

The Gundam 4th is very much like a Generic version of the Gundam GP02A in the sense that most of their damage will come from their massive AoE EX Skill blast, and will suffer from self-inflicted debuffs after they're able to use it.

This MS' EX Skill deals two instances of damage, one 487% and one 365%, which adds up to a total of 852%. This benefits from two 48% EX damage buffs, though one of them is locked behind Transcendent Lv. 5. Just like the GP02A, this unit does not have any EX Gauge restoration or recovery buffs, so it'll take a while to activate this AoE skill. Using this EX Skill also reduces its EX gauge recovery by 36% for 20 seconds, so its 2nd cast will take even longer than the first.

The Gundam 4th benefits from a 200,000 max damage buff from its Skill 2, so it's well capable of reaching extremely high amounts of damage with its EX Skill.

While the Gundam 4th's 852% may seem small in comparison to the GP02A's 2008% ATK multiplier, the GP02A's ATK is only at 3,626 at max Lv. 150 investment while the Gundam 4th has 7,973, which is more than double the GP02A's. Moreover, the Gundam 4th has two 48% EX Damage buffs while the GP02A only benefits from one of those, and a stacking damage buff that maxes out at 20%, which it may or may not fully be able to stack.

Finally, as for their signature pilots, the GP02A's Anavel Gato does not have any skills that increase his mobile suit's EX Skill damage, while Luth Kassel grants 26% more EX Skill damage.

Becomes a Vegetable After EX Skill

Unlike the GP02A, the Gundam 4th is a rather well-rounded mobile suit outside of its EX Skill, as it benefits from 99% more beam damage, 48% accuracy, and 48% evasion. However, once it uses its EX Skill, it loses all three buffs.

Once these buffs are gone, it benefits only from its Transcendent Skills (which don't amount to much) and EX damage buffs (which it won't be able to cast quickly considering its EX gauge recovery self-debuff).

Needs Potential Unleashed and Transcendence To Be Effective

When fully Transcended, the Gundam 4th benefits from a 25% accuracy buff, a 36% beam damage buff, and the 48% EX damage buff we've already discussed. Fully Transcending this unit not only makes it a stronger AoE threat, but a better anti-evasion unit too considering that it benefits from 73% accuracy.

Potential Unleashed is also extremely important on this unit considering that doing so improves the EX Skill's damage numbers, and this unit is extremely reliant on its EX Skill. Sadly, not a lot of players have this unit at Potential Lv. 5 since it does not have a dedicated gacha banner with higher pull rates.

Overall, the Gundam 4th is potentially an extremely powerful unit. However, it needs high Potential Levels to perform at a high level, and it's extremely unlikely for players to have it at these high Potential Levels. It also has plenty of risks associated with it, as this unit can most definitely die before it gets to use its EX Skill. It's a Gundam-Type unit, which means that Char's Z'Gok can draw aggro towards it while making it take increased damage. It's also a Red-type, which means it has a type disadvantage against the strongest DPS unit in the game: the Zeong. Both these units pose a huge threat against the Gundam 4th, and both units are also very popular in the PvP meta.

It's a good unit for PvP if you somehow have it at high Potential Levels, though you're probably better off using Ez8-enhanced meta DPS units. It's also decent in PvE, though it might struggle with the game modes with longer matches considering that it loses its buffs after EX Skill usage, and subsequent EX activations will take longer than the first.

Best Pilot

Pilot Rarity

Series
Mobile Suit Gundam Side Story: Space, To the End of a Flash

Luth Kassel is the Gundam 4th's best pilot thanks to the 26% EX damage buff he grants, which greatly improves the Gundam 4th's already deadly EX Skill. He grants 76% ranged sense and another 77% ranged sense for the first 30 seconds of combat, improving its regular weapons. His 30-second 20% buffs to both accuracy and evasion improve its anti-evasion capabilities and its survivability. With Luth piloting this MS, the duo benefits from a maximum of 93% accuracy and 68% evasion.

The Unit Enhancement setup above is a multi-purpose setup meant to excel across different game modes. However, depending on the content, there may be situations where it is better to invest more points into accuracy.

You can try adjusting your Unit Enhancement setup if you can't win against certain stages. However, this will not guarantee you a win, so you should also factor in all the other elements in play and adjust accordingly.
